i tried this once manually ... remotely from work through octoprint. It broke the part of 2mm above the rintplate and shot it across the room. Crealty Ender 3 magnetic base has crazy adhesion.
@@demoniack81 My LK4 has a similar buildtak surface, and there's no way it would ever release something without a fight... Cura gave one of my first prints a 15mm brim for some reason... I needed a hammer and a chisel to get it off!
I tried that a few weeks back. I was thinking"only thinking" of a tool I needed,, and after a few hours.. Adds began to pop up.i was in my workshop...I wasn't talking to nobody.. but jet the add was precisely the tool I needed.. I was littely in shock. ..well also I bought it. :-)
This is so cool! I was planning on trying something almost exactly like this, even down to the scraper or plow you described at the end to aid with part removal. It's great to see how easy it can be. The one idea I had that you haven't touched on here is: shimming or mounting the printer so it's tilted towards the front slightly. That way gravity helps clear the parts off the build plate after they've been dislodged. Great video!
I always had the same idea to do this. But got limited due to less knowledge on Gcode editing. Anyways you have the most original content brother. Inspired. Keep going . All the best.
There's a long standing bug with Prusa's handling of MMU2 with TPU, where the prints are done at 35% speed, making an already long MMU print go from hours to days. So setting the speed back in filament settings with M900 K60; Filament gcode M220 S100; Abe Speed Fixing Awesome video!
Have you looked into m23 and m24? It allows you to start an SD print in the gcode, so you can just select and print the next file instead of concatenating them all into one file.
Love the idea! I do a lot of repetitive prints myself and have wanted to figure out an automated solution for clearing my bed. I was brainstorming some kind of robot arm that's beyond my engineering abilities, this is simple and only needs the tools I already have. Brilliant!
To improve on this idea you could create a robot that has a microphone to listen to the sounds the printer makes that then sends a bar across the top of the print bed after a sequence of sounds are made by the printer (the sounds could be set in G code). This also means that the part can be pushed further, and it could then land in a box.
@@jameshamstead4709 I think using a servo with an arm attachment would be a nice way to sweep prints off the bed. Although, I understand that this would be limited to open boards that expose the servo controls. Marlin supports the M280 command to set position of the servo. Do proprietary boards like the Creality ones have servo outputs?
This is great if you are building something large with multiple small pieces you can just leave it run over night and in the morning you just assembe everything together
@@cameronmalchow1837 Yup, the plough would start a few mm above the nozzle- its not meant to scoop prints off the bed like a spatula, more of pushing surface to knock parts off without having to rely on directly contacting the extruder bits, giving you a wider area to push with. Like a bumper of sorts.
This is a great idea! You can get this to work with taller prints (or prints of any size) by replacing the "Move up and back" code at 4:15 with these lines: G91 G1 Z10 G90 G1 X105 Y195 G1 Z1 F3000 The G92 means relative positioning, which means the G1 Z20 moves 20 mm from /wherever/ you are now. G90 switches back to "normal mode," so that the other commands work the same way you expect. This change means that moving the print-head up works even if your print is bigger than 50 mm (or any size), as long as you have a small gap between the top of the part and the highest z-height available.
Can you make the 3d printer wait until the bed is cooled down before pushing it off? I print on glass and prints are very hard to remove when the bed is still warm.
When i read the title, i knew exactly what you were going to do! But to be honest, i wouldn't ever have come up with the idea otherwise. Here's a variation on the detachment sequence i can think of on the spot: ; maybe move to the back of the bed here first? M106 ;set fan to full speed to facilitate cooling M140 S30 ;set bed cool enough to detach the print, start cooldown M190 R60 ;cool the nozzle low enough to not mar the print, wait for nozzle to reach temperature M180 R30 ;actually wait for the bed to get cold ; insert the movement commands to knock down the print here This is Marlin-specific, not Repetier, and not sure how far back the supported versions go, but anything semi-recent should be OK.
There's an M-command which tells the machine to rewind the program and restart it. For CNC mills and lathes it's the M31 command I believe. I don't know if it's the same for Marlin 3D printers, but maybe you should try that, it'd be much less hassle as you could just add it in the slicer and the filesizes would be much smaller for even larger production runs.
@@make.anything thats why this is called a Community we help each other while checking on the loop you should also look into additive offset which allows you to repeat it as many times as you want with a given x y z offset
M31 is the "Print Time" command, in Marlin. Sadly, I cannot find any restart, loop, jump, or conditional branch commands of any sort. The closest is M32, which allows you to run another G-Code file, which could possible be used to start the same file again, but there is a risk of stack overflow, if previous g-code is not aborted when a new file is run. Marlin either does not have all g-codes implemented, or their documentation is incomplete.
Just a few ideas while watching your cool video. You could tilt the printer 45° forward so the parts fall off better and also shouldn't you write Z commands first like z20 x200 y50 so that the head always moves up and out of the way before table moves or is that automatic?
Tilting the printer is a clever idea! As far as the order of the coordinates, the xy and z move together unless they're put as separate lines, which I did do for a few of the movements
F stands for feed, when using a CNC mill or other similar machine, the speed or S is for RPM of the tool. Edit: G code is modal, that means if you wanted to move to say X1 Y1 Z1 but you wanted to do each axis at a time you could type G01 X1 F10 Y1 Z1 Because any command or value you have entered already, stays the same until you say otherwise.
Thanks, this worked perfectly. Printing in PETG which sticks extremely well to the bed so I added; M190 R40 before "move print " So that when Bed temperature reaches 40c the print easily releases.
what kind of bed coating do you have? I'm interested in trying it with PETG, i've had this filament for a while but hasn't tried it yet, but i've heard that it is difficult to remove it from PEI and some glue should be used in between.
Alex polyenov Using a textured Prusa bed, I’ve had a few fails with the print not releasing at 40c. PLA would be better for sure. Once I get it sorted I’ll post settings.
@@nicokypreos Thank you! Much appreciated. I'll keep an eye for the update. My Prusa bed is smooth PEI, so i imagine it would be even stronger adhesion than textured. I'm specifically interested in PET/PETG for their properties. PLA wouldn't work for me for its very low melt temp/
Did I miss the warnings for larger prints and / or other materials like PLA? TPU / PETG might stick to well the 2nd or 3d time you're using the same spot. What's about bending the x axis if prints stick to well? What's about collision detection some printers have?
Oh hey, I've used this method before! I used to print a ton of keyboard keys but my area has frequent power surges (but I couldn't afford a decent UPS at the time). So rather than print a big batch of keys at once, I printed on a squeaky clean glass build plate and waited for the key to cool off. Then a printed "bumper" (attached to the extruder) would bump into the key and knock it off into a cup on my desk. It was super effective and once I get my printer printing consistently enough for well-fitting keys, I'll be going back to this.
i had this idea a long time ago and i think ive commented it on several 3d printer videos but idk when where and anything. but its great to see the idea pop into others head aswell and actually become real :D
Really good video. Am in the process of doing the same on my cr10s. I am using the secondary extruder output on the motherboard to lower a long scraper. At the end of the print the y axis moves as far forward as possible. Then I cool the bed and leave for a few minutes. At this point the e1 stepper lowers a long blade to the bed surface and the y axis moves backwards slowly. In theory this should work as my printer is tuned exceptionally well. I don’t use any printed platform additions or things like glue or tape. Also I have found that even using all of the bed providing it’s cooled right down and also the model is cooled the prints come off with no effort at all.
thanks for the video very helpful. coudnt get the beeps to work but the automate code you made worked perfectly for what i needed. I switched the G1 to G0 and didnt need to clean the extruder in between prints. next im trying a G4 code to let it cool a little bit, then ill be designing pieces to scoop them into the trap. wish me luck.
If you're using an adhesive that would release as it cools, you can use the G4 Dwell command to make the printer sit there and wait as it cools, and then when the time you specify has passed do the push procedure. This is what I did before I got PrintBite+ which doesn't need that cooldown time to release.
Ya sometimes I have to work to get the model off with a scraper on my glass bed. Sometimes I did run several of the same part and this would be nice but I don't want to intentionally decrease my adhesion. Oh well.
I'm new to printing, but I program milling machines.. where you manually entered for the wipe on the brush you shouldn't have to repeat the x value if its not changing. Great video!
😂 great job. I have bee doing this with octoprint for the last few months (removing the print from the bed), while at work. Never crossed my mind to do it via gcode, and with multiple repeat models. I have done a range of small to medium prints. With very large surface area used on the bed (some 175mm x 175mm surface area has been the largest). Now I have an easier way, now I can really print nonstop
I've heard this idea from Sanjay Mortimer in a conversation with Tom Sanladerer when they were talking about tool changing and belt drives if I remember correctly. But you are the first person I see to actually use this techniqe. Well done mate! Oh and just increase the distance between skirt and object to not drag plastic gunk into your prints. Cheers!
Considering that printer has Ultrabase, you could also wait for the bed and nozzle to cool before knocking prints off. Considering how PLA and PETG practically jump off the bed below 30C, It should be much healthier for the bed and get rid of the melting problem. It'd add about ten minutes between each print, but it'd help keep things reliable.
Thanks, some very good stuff in this video :) but this is for the PLA, for others types of fillament like PETG, need to wait for bed to cooldown first down to around 30-40°C before kicking the model out. Is that possible?
That's really cool. Always good to see people experiment outside the box like this. Unfortunately my bed adhesion would break parts off the print head instead regardless of bed temp. Oh... that brush. It might add a bit of wear/deformation to the nozzle orifice. Just saying. ☺️
Should have put the wire brush on the left hand side..it stops the stringing from ending up on the print plate..this has been done many times before. Knocking the prints off is something i havent seen before tho.
I wonder whether incorporating the brim into the model to have a say 45° lip and putting a similarly angled wedge on the print head could help reduce forces on the print head and facilitate levering the piece off the build plate like so : model-brim-lip |_/ /_ print head? Print head wedge would need to clear print nozzle end though. Second crazy idea, print out filament on plate as it's spooled back on and fed through again to mix colours along new filament length lol
Perhaps also a pause with G4 Px (x number of miliseconds) before removal to let the print bed cooldown for easier removal... Or even better: M109 Rx (x extruder temperature to wait for) M190 Rx (x bed temperature to wait for)-->this one depends on software temperature tolerance settings
When I updated Cura, It added in a sweet little piece of gcode where it makes a couple lines of the left side of the bed to make sure it's flowing filament. It's a great little feature they added in.
Donyou by any chance have a video on bed leveling. At the moment i have been thinking of buying a BLtouch. But at the same time while i look at your videos i might not have to do that. Also my next quick question is if you can have profiles? Like for example you have your default print movement settings in profile 1. But profile 2 has what you did in this video. And say you mess something up. You ciuld just go back to profile 1. Also do you have to paste stuff into the gcode script? Or is there another simple way of printing multiple things without having to mess with gcode well…..code..?
Loved the googly eyes. Now I want some for my Mk3. Would it not help to tape a rolled up plastic wedge or small diameter pvc to the paper to give your piece some tilt and let gravity slide it on down instead of waiting for the next piece to push it down.
how about a Gcode to create a claw for the print head, once it's done printing (and cooled down enough), it moves into the claw (probably with some clips that'll catch on the top of the print head), and then moves into a position where it can pick up something with the claw? or perhaps if there's a print head with 2 fans that can be controlled individually, rewire one of the fans to run a little motor (probably with a gear system attached) to grab stuff and assemble it off the bed or a see saw style lever, that the print head moves to press down (and potentially trigger a cool mechanism)
This must be the best tip for 3d printing so far. Very useful for mass production. What is the code in order for printer to wait until bed is cold then knock off the parts?
M190 R30 30 is just an arbitrarily chosen temperature by me where i feel it should release; experiment with this value. R is necessary to actually wait for cooldown, if temperature is specified with S like usual, only the warmup sequence waits. This G-code is Marlin specific. In Repetier, no dice.
I have a belt printer, but as you might know due to the 45 degree head, some thing don't print as well, and some print better. But I wanted belt printer that has the traditional xyx. So I was getting ready to convert one of my bed slingers, but I might just try this first. One thing I plan to do is on my models build in some kind of angel relief so a scraper and get under that and pull it off. I know this is an old video, but it still great. And one of my printers is an i3 Mega
There is indeed a gcode command for looping, it only works with sd card printing. M808 L[count of loops/*0* for infinite] [the gcode you want to loop...] M808
Cool idea ! deff work great with some prints and not so much with others. and for the peeps that have to chop at your print to get it off your glass, this is deff not for you. Use your judgment and dont break your printer.
Yeah, I don't fancy using my printer as a hammer, I'll just have to enable a bed cooldown (which makes my prints pop off the glass like butter) then reheat, rinse, (haha) and continue..
What makes this possible is the ultrabase surface, if you indeed do that on a buildtak or blue tape, the printer will most likely get stuck and break something. But the ultrabase somehow stick well enough that you will never have a print come off on it's own, but if you try pushing the print, it'll just remove easily. Especially if you let it cool down.
Love the vids man. I've been printing for a good couple of years and I learned a lot of tips from ya. And thanks for the Fusion tuts. Great stuff and very inspiring! I do a lot of full cosplay prints and is awesome to finish and paint. Really getting a good hold of making my own designs and learned quite a bit from watching your vids. Thanks!
At 10:20 your hotend travels off the plate to z home. It is not supposed to. It is supposed to home on the plate (5mm to the right) that way the bit of ooze will stick to the plate, and when your hotend lifts up 20mm before traveling to the print start point, it pulls the ooze off of the nozzle to clean it.
There are 3D printers that have a rolling build platform which is like a treadmill. After a piece is printed it is rolled forward out of the way to make room for a new object. As those objects round the edge of the treadmill print bed they are literally forced off of it and into whatever collection bin you have set up. Can that be adapted to any kind of 3D printer? To avoid the stringing across the print bed how about mounting the steel brush to the opposite side instead? That way each new pass starts without strings to glob up the works.
I would use a nozzle flow/purge line before each print. Just put them off to the side and each one at a different y position. That way you start each object with a good flow, as if you printed a skirt.
I did that to help preserve the adhesion of the print surface a bit longer. Printing in the same spot over and over can wear out the special coating... Or at least that's my theory :P
This works really well on a Printer that has a bed that moves up and down. I use this method on the XYZ Davinci and it works. No need for paper I only place a bin and collect the prints.
How does this not interfere with Bed Adhesion especially right after the print is done? It takes like 5-7 minues for my Printbed to cool off enough to remove the Print itself, and its the same printer.
It depends on bed leveling and the specific model.. might need a low density raft. I think it's possible, but would certainly test the adhesion strength before going full auto
Be really careful about wire brushes around the heater, usually there's a tiny gap between the cartridge and the insulation, it develops over time perhaps, it may short out and or short to your therm sensor, ( found this out the hard way), I usually avoid the wired side it's tough to keep them sealed with all the thermal cycling I guess. But just something to think about if this type of setup is unattended
Nice. You might be able to reduce the between-print pause (and resultant blobs) by removing the wait-for-temperature command at the start of the 2nd and beyond prints. Even if the printer is already at the correct temperature it will wait for a few seconds for the temperature anyway. For people comfortable using the command line, the "cat" terminal command can be used to concatenate the files. "cat AMBI-1.gcode AMBI-2.gcode AMBI-3.gcode > AMBI-auto.gcode", or, fancier, "cat AMBI-?.gcode > AMBI-auto.gcode"
Have you tried folding thicker paper into a triangle shape pattern and adding it instead of the plain paper? This could be fixed on two sides and gives a stable base for the finished parts to travel on. At least these are used on CNC’s to keep shavings off of the linear guides
I like your Idea. Maybe a little bit mechanical updates are needed but ... nice! ... But you only can do that with the glas-plate. And if you wait until the plate is cooled down than you can also remove bigger parts automaticly from the built plate.
This is exactly what I was looking for. I'd like to be able to run Octoprint on an Android phone and print off multiple objects while out of town. Them just come home and pick up and clean all the printed pieces. I've been doing a lot of mods and upgrades to my JG Aurora A5, and I've removed the "3d Printer" nameplate off of the gantry, I guess I could design and print a scraper/pusher that attaches in the same place.
If i tried this it would break my printer. My prints stick too well
Let the print cool down first! Mine stick absurdly as well, but after reaching 60°C or less, they come off just by touching it. (ABS 230C-110C)
There should be a "sleep" Gcode command. Use that in your favor...

Ps. In the End GCode add:

G1 E-2

I have an Ender 3 Pro and I was thinking the same... if I tried this I'm not sure what would break, but I'm sure _something_ would.
@@demoniack81 My LK4 has a similar buildtak surface, and there's no way it would ever release something without a fight... Cura gave one of my first prints a 15mm brim for some reason... I needed a hammer and a chisel to get it off!
I guess you need to let it cool off xD
@@marcosmoura911 yes 😇
Probably better on glass
I was literally wondering about this yesterday... Google can definitely read my thoughts.
I tried that a few weeks back.
I was thinking"only thinking" of a tool I needed,, and after a few hours..
Adds began to pop up.i was in my workshop...I wasn't talking to nobody.. but jet the add was precisely the tool I needed..
I was littely in shock. ..well also I bought it. :-)
that's doubleplusgood
I just did the same! At the beginning of the week i started to print a cable chain like that. I have now around 2,5 m long chain. Same idea!
Woah, an endless chain?
Next, do agcode that assembles and installs it into your printer too!
Please share it :)
@@aelooser I wonder if he is still printing
@@superpixelgamer7775 pretty sure
Devin, you are such an innovator. This isn't just fun and smart, but will genuinely change how some people can make their living. WOW man.
me too, this is huge for my wallet
This is so cool! I was planning on trying something almost exactly like this, even down to the scraper or plow you described at the end to aid with part removal. It's great to see how easy it can be. The one idea I had that you haven't touched on here is: shimming or mounting the printer so it's tilted towards the front slightly. That way gravity helps clear the parts off the build plate after they've been dislodged. Great video!
Who's got some g-code wisdom to share? What's your favorite command.. what else can I do??
I always had the same idea to do this. But got limited due to less knowledge on Gcode editing. Anyways you have the most original content brother. Inspired. Keep going . All the best.
Make Anything g1 should be modal, so you can just enter it once and it will be that way until you change it, just like feedrate, so be careful.
There's a long standing bug with Prusa's handling of MMU2 with TPU, where the prints are done at 35% speed, making an already long MMU print go from hours to days.
So setting the speed back in filament settings with
M900 K60; Filament gcode
M220 S100; Abe Speed Fixing
Awesome video!
Have you looked into m23 and m24? It allows you to start an SD print in the gcode, so you can just select and print the next file instead of concatenating them all into one file.
Why you don`t use g23 to repeat the cycle?
Love the idea! I do a lot of repetitive prints myself and have wanted to figure out an automated solution for clearing my bed. I was brainstorming some kind of robot arm that's beyond my engineering abilities, this is simple and only needs the tools I already have. Brilliant!
I would love to see a 3D printing challenge series based on the comments
To improve on this idea you could create a robot that has a microphone to listen to the sounds the printer makes that then sends a bar across the top of the print bed after a sequence of sounds are made by the printer (the sounds could be set in G code). This also means that the part can be pushed further, and it could then land in a box.
@@jameshamstead4709 I think using a servo with an arm attachment would be a nice way to sweep prints off the bed. Although, I understand that this would be limited to open boards that expose the servo controls. Marlin supports the M280 command to set position of the servo. Do proprietary boards like the Creality ones have servo outputs?
@@jameshamstead4709 how about a scraper option for prints with a larger atachment profile?
This man is the most influencial guy in the hole makers community!! Thank you Devin!!
I love the hole maker community, they make great holes
I use m99 loop to print production parts 24/7 with filament runout detection. make sure to home at end of program and 3x3 abl and you're rocking.
This is great if you are building something large with multiple small pieces you can just leave it run over night and in the morning you just assembe everything together
I think some kind of snowplow-like attachment on the front of your extruder might help push off smaller pieces
@@H0B0J03 without getting in the way of the print head and current print?
@@cameronmalchow1837 Yup, the plough would start a few mm above the nozzle- its not meant to scoop prints off the bed like a spatula, more of pushing surface to knock parts off without having to rely on directly contacting the extruder bits, giving you a wider area to push with. Like a bumper of sorts.
There's a plugin on octoprint for this I think. No SD Card limitation, the computer loops through the code without storing the whole thing in SD Card.
What is the plug-in called?
It's called "Continuous Print"
You are just the most creative 3D-Printing guy on RUclips!
The auto nozzle brushing is frickin brilliant. My hats off to you
This is a great idea! You can get this to work with taller prints (or prints of any size) by replacing the "Move up and back" code at 4:15 with these lines:
G91
G1 Z10
G90
G1 X105 Y195
G1 Z1 F3000
The G92 means relative positioning, which means the G1 Z20 moves 20 mm from /wherever/ you are now. G90 switches back to "normal mode," so that the other commands work the same way you expect. This change means that moving the print-head up works even if your print is bigger than 50 mm (or any size), as long as you have a small gap between the top of the part and the highest z-height available.
Can you make the 3d printer wait until the bed is cooled down before pushing it off?
I print on glass and prints are very hard to remove when the bed is still warm.
When i read the title, i knew exactly what you were going to do! But to be honest, i wouldn't ever have come up with the idea otherwise.
Here's a variation on the detachment sequence i can think of on the spot:
; maybe move to the back of the bed here first?
M106 ;set fan to full speed to facilitate cooling
M140 S30 ;set bed cool enough to detach the print, start cooldown
M190 R60 ;cool the nozzle low enough to not mar the print, wait for nozzle to reach temperature
M180 R30 ;actually wait for the bed to get cold
; insert the movement commands to knock down the print here
This is Marlin-specific, not Repetier, and not sure how far back the supported versions go, but anything semi-recent should be OK.
Great suggestions 👍
Great idea - I think you should you a softer bristle brush though as the wire one may damage the nozzle over time.
There's an M-command which tells the machine to rewind the program and restart it. For CNC mills and lathes it's the M31 command I believe. I don't know if it's the same for Marlin 3D printers, but maybe you should try that, it'd be much less hassle as you could just add it in the slicer and the filesizes would be much smaller for even larger production runs.
The real pro tips are in the comments 😉 thanks!
THIS! and add an offset to reach a clean build plate area
@@make.anything thats why this is called a Community we help each other while checking on the loop you should also look into additive offset which allows you to repeat it as many times as you want with a given x y z offset
M31 is the "Print Time" command, in Marlin. Sadly, I cannot find any restart, loop, jump, or conditional branch commands of any sort. The closest is M32, which allows you to run another G-Code file, which could possible be used to start the same file again, but there is a risk of stack overflow, if previous g-code is not aborted when a new file is run. Marlin either does not have all g-codes implemented, or their documentation is incomplete.
Just a few ideas while watching your cool video. You could tilt the printer 45° forward so the parts fall off better and also shouldn't you write Z commands first like z20 x200 y50 so that the head always moves up and out of the way before table moves or is that automatic?
Tilting the printer is a clever idea! As far as the order of the coordinates, the xy and z move together unless they're put as separate lines, which I did do for a few of the movements
I’m watching while printing on my anycubic i3 mega I bought based on your recommendation and I love it thank you for this great content 👍
That brush is actually genius. PETG always does that blobbing crap and I have to sit there and manually scrape it off at just the right time lmao
This is pure artistic genius. Love the wire brush move!
F stands for feed, when using a CNC mill or other similar machine, the speed or S is for RPM of the tool.
Edit: G code is modal, that means if you wanted to move to say X1 Y1 Z1 but you wanted to do each axis at a time you could type
G01 X1 F10
Y1
Z1
Because any command or value you have entered already, stays the same until you say otherwise.
Thanks, this worked perfectly.
Printing in PETG which sticks extremely well to the bed so I added;
M190 R40
before "move print "
So that when Bed temperature reaches 40c the print easily releases.
what kind of bed coating do you have? I'm interested in trying it with PETG, i've had this filament for a while but hasn't tried it yet, but i've heard that it is difficult to remove it from PEI and some glue should be used in between.
Alex polyenov
Using a textured Prusa bed, I’ve had a few fails with the print not releasing at 40c. PLA would be better for sure.
Once I get it sorted I’ll post settings.
@@nicokypreos Thank you! Much appreciated. I'll keep an eye for the update. My Prusa bed is smooth PEI, so i imagine it would be even stronger adhesion than textured. I'm specifically interested in PET/PETG for their properties. PLA wouldn't work for me for its very low melt temp/
@@alexp2011a ok so using PETG and Textured bed, releasing temperature is 27c, print slides off
Did I miss the warnings for larger prints and / or other materials like PLA? TPU / PETG might stick to well the 2nd or 3d time you're using the same spot. What's about bending the x axis if prints stick to well? What's about collision detection some printers have?
Oh hey, I've used this method before! I used to print a ton of keyboard keys but my area has frequent power surges (but I couldn't afford a decent UPS at the time). So rather than print a big batch of keys at once, I printed on a squeaky clean glass build plate and waited for the key to cool off. Then a printed "bumper" (attached to the extruder) would bump into the key and knock it off into a cup on my desk.
It was super effective and once I get my printer printing consistently enough for well-fitting keys, I'll be going back to this.
i had this idea a long time ago and i think ive commented it on several 3d printer videos but idk when where and anything. but its great to see the idea pop into others head aswell and actually become real :D
Really good video. Am in the process of doing the same on my cr10s. I am using the secondary extruder output on the motherboard to lower a long scraper. At the end of the print the y axis moves as far forward as possible. Then I cool the bed and leave for a few minutes. At this point the e1 stepper lowers a long blade to the bed surface and the y axis moves backwards slowly. In theory this should work as my printer is tuned exceptionally well. I don’t use any printed platform additions or things like glue or tape. Also I have found that even using all of the bed providing it’s cooled right down and also the model is cooled the prints come off with no effort at all.
you can use a piece of silicone sheet to wipe the nozzle instead of the brush as seen on most of the purge buckets on thingiverse
thanks for the video very helpful. coudnt get the beeps to work but the automate code you made worked perfectly for what i needed. I switched the G1 to G0 and didnt need to clean the extruder in between prints. next im trying a G4 code to let it cool a little bit, then ill be designing pieces to scoop them into the trap. wish me luck.
You could use M32 or M24 to load "sub programs" from SD card and create one master file then just change home offset (M206) between prints.
Piece of cardboard from a cereal box may work better than a sheet of paper. Could create a trough so they slide into a box.
Idk if mine would knock the print off or sit there and bind due to being so stuck to the glass
If you're using an adhesive that would release as it cools, you can use the G4 Dwell command to make the printer sit there and wait as it cools, and then when the time you specify has passed do the push procedure. This is what I did before I got PrintBite+ which doesn't need that cooldown time to release.
Gary Brower if it’s glass your probably fine. Try manually moving the bed in the menu when the print is done
I had the same thought. I have a hard enough time trying to pry the part off the glass.
My prints with a reasonable amount of surface are welded to my plate and need a blade to pry them off...
Ya sometimes I have to work to get the model off with a scraper on my glass bed. Sometimes I did run several of the same part and this would be nice but I don't want to intentionally decrease my adhesion. Oh well.
I'm new to printing, but I program milling machines.. where you manually entered for the wipe on the brush you shouldn't have to repeat the x value if its not changing. Great video!
😂 great job. I have bee doing this with octoprint for the last few months (removing the print from the bed), while at work. Never crossed my mind to do it via gcode, and with multiple repeat models. I have done a range of small to medium prints. With very large surface area used on the bed (some 175mm x 175mm surface area has been the largest).
Now I have an easier way, now I can really print nonstop
I've heard this idea from Sanjay Mortimer in a conversation with Tom Sanladerer when they were talking about tool changing and belt drives if I remember correctly. But you are the first person I see to actually use this techniqe. Well done mate! Oh and just increase the distance between skirt and object to not drag plastic gunk into your prints. Cheers!
I like how you’re always pushing the tech. Great build!
IT tOoK mE foREvER TO FInD tHIS vIdeO AGaIN!!! RUclips SUCKS. this is honestly the best video on 3d printing I've seen. Thank you so much.
Considering that printer has Ultrabase, you could also wait for the bed and nozzle to cool before knocking prints off. Considering how PLA and PETG practically jump off the bed below 30C, It should be much healthier for the bed and get rid of the melting problem. It'd add about ten minutes between each print, but it'd help keep things reliable.
Thanks, some very good stuff in this video :) but this is for the PLA, for others types of fillament like PETG, need to wait for bed to cooldown first down to around 30-40°C before kicking the model out. Is that possible?
Yes, you could add the gcode for that
That's really cool. Always good to see people experiment outside the box like this.
Unfortunately my bed adhesion would break parts off the print head instead regardless of bed temp.
Oh... that brush. It might add a bit of wear/deformation to the nozzle orifice. Just saying. ☺️
Haha yeah I think my printer also would break , my models stick so damn good I need quite a lot force to get it off the bed.
Does 3d printers support G00 movement? I believe it should make the motor moves faster (well...at least it does in a cnc mill)
Just a wonderful idea! You don't know you much you do my life easier with all this g-code modifications! Very cool job :)
Should have put the wire brush on the left hand side..it stops the stringing from ending up on the print plate..this has been done many times before. Knocking the prints off is something i havent seen before tho.
I wonder whether incorporating the brim into the model to have a say 45° lip and putting a similarly angled wedge on the print head could help reduce forces on the print head and facilitate levering the piece off the build plate like so : model-brim-lip |_/ /_ print head? Print head wedge would need to clear print nozzle end though. Second crazy idea, print out filament on plate as it's spooled back on and fed through again to mix colours along new filament length lol
I think that's a great idea!
Man you're a genious! Everytime you come up with original ideas! Incredible
Perhaps also a pause with G4 Px (x number of miliseconds) before removal to let the print bed cooldown for easier removal...
Or even better:
M109 Rx (x extruder temperature to wait for)
M190 Rx (x bed temperature to wait for)-->this one depends on software temperature tolerance settings
Seems good. Larger parts vs well stuck on a hot bed.
Would be interested to see a larger part coming off of a hot bed ?
I have been doing this for a while but i always had the problem of the objects falling under the print bed
your paper idea solves this
When I updated Cura, It added in a sweet little piece of gcode where it makes a couple lines of the left side of the bed to make sure it's flowing filament. It's a great little feature they added in.
Donyou by any chance have a video on bed leveling. At the moment i have been thinking of buying a BLtouch. But at the same time while i look at your videos i might not have to do that.
Also my next quick question is if you can have profiles? Like for example you have your default print movement settings in profile 1. But profile 2 has what you did in this video. And say you mess something up. You ciuld just go back to profile 1.
Also do you have to paste stuff into the gcode script? Or is there another simple way of printing multiple things without having to mess with gcode well…..code..?
Loved the googly eyes. Now I want some for my Mk3. Would it not help to tape a rolled up plastic wedge or small diameter pvc to the paper to give your piece some tilt and let gravity slide it on down instead of waiting for the next piece to push it down.
how about a Gcode to create a claw for the print head, once it's done printing (and cooled down enough), it moves into the claw (probably with some clips that'll catch on the top of the print head), and then moves into a position where it can pick up something with the claw?
or perhaps if there's a print head with 2 fans that can be controlled individually, rewire one of the fans to run a little motor (probably with a gear system attached) to grab stuff and assemble it off the bed
or a see saw style lever, that the print head moves to press down (and potentially trigger a cool mechanism)
Totally new to 3d printing, and really enjoy your videos. Very cool use of G code.
This must be the best tip for 3d printing so far. Very useful for mass production. What is the code in order for printer to wait until bed is cold then knock off the parts?
M190 R30
30 is just an arbitrarily chosen temperature by me where i feel it should release; experiment with this value.
R is necessary to actually wait for cooldown, if temperature is specified with S like usual, only the warmup sequence waits.
This G-code is Marlin specific. In Repetier, no dice.
I have a belt printer, but as you might know due to the 45 degree head, some thing don't print as well, and some print better. But I wanted belt printer that has the traditional xyx. So I was getting ready to convert one of my bed slingers, but I might just try this first. One thing I plan to do is on my models build in some kind of angel relief so a scraper and get under that and pull it off. I know this is an old video, but it still great. And one of my printers is an i3 Mega
There is indeed a gcode command for looping,
it only works with sd card printing.
M808 L[count of loops/*0* for infinite]
[the gcode you want to loop...]
M808
Done this, anycubic ultrabase helps a lot.
Sanjay from E3D did this with their original hotends fan mounts like what 7 years ago?
Props man! Fantastic! Just a little creativity and a few knowledge you showed it help a lot!
thanks for that educational video. am so glad to find ur channel ))
Is there some way to loop G-code? It would make the file creation much easier and enable infinite printing.
Cool idea !
deff work great with some prints and not so much with others.
and for the peeps that have to chop at your print to get it off your glass, this is deff not for you.
Use your judgment and dont break your printer.
Yeah, I don't fancy using my printer as a hammer, I'll just have to enable a bed cooldown (which makes my prints pop off the glass like butter) then reheat, rinse, (haha) and continue..
What makes this possible is the ultrabase surface, if you indeed do that on a buildtak or blue tape, the printer will most likely get stuck and break something. But the ultrabase somehow stick well enough that you will never have a print come off on it's own, but if you try pushing the print, it'll just remove easily. Especially if you let it cool down.
Love the vids man. I've been printing for a good couple of years and I learned a lot of tips from ya. And thanks for the Fusion tuts. Great stuff and very inspiring! I do a lot of full cosplay prints and is awesome to finish and paint. Really getting a good hold of making my own designs and learned quite a bit from watching your vids. Thanks!
At 10:20 your hotend travels off the plate to z home. It is not supposed to. It is supposed to home on the plate (5mm to the right) that way the bit of ooze will stick to the plate, and when your hotend lifts up 20mm before traveling to the print start point, it pulls the ooze off of the nozzle to clean it.
good idea, but why you don't move the brush to left side ???
There are 3D printers that have a rolling build platform which is like a treadmill. After a piece is printed it is rolled forward out of the way to make room for a new object. As those objects round the edge of the treadmill print bed they are literally forced off of it and into whatever collection bin you have set up. Can that be adapted to any kind of 3D printer?
To avoid the stringing across the print bed how about mounting the steel brush to the opposite side instead? That way each new pass starts without strings to glob up the works.
I would use a nozzle flow/purge line before each print. Just put them off to the side and each one at a different y position. That way you start each object with a good flow, as if you printed a skirt.
Now does gcode has some kind of a for loop command?
That would make it much more feasible
It does indeed
if you put a keyboard on the platform you can also add gcode do order new filament when it runs out
That's badass. The brush idea is genius.
Why were the squircles printed in different positions? Great idea!
I did that to help preserve the adhesion of the print surface a bit longer. Printing in the same spot over and over can wear out the special coating... Or at least that's my theory :P
This works really well on a Printer that has a bed that moves up and down. I use this method on the XYZ Davinci and it works. No need for paper I only place a bin and collect the prints.
Can you post the start/stop codes in the description?
How does this not interfere with Bed Adhesion especially right after the print is done? It takes like 5-7 minues for my Printbed to cool off enough to remove the Print itself, and its the same printer.
Just lower down the print bed a little bit.
I'm not interested in autoremoval, but brush on unused end of bed is absolutly brilliant idea.... going to print brush-holder with your logo... :)
Brilliant. I was hoping to add some automation to my new 3D printer. This is just the start I need, thanks.
There's definitely room for optimization, but this is a really cool, simple hack. Thanks for the video!
Do you think this would work on a glass bed hairspray setup? I think my prints stick way to well to the bed for this to work.
It depends on bed leveling and the specific model.. might need a low density raft. I think it's possible, but would certainly test the adhesion strength before going full auto
you can join all files together in command line like this:
copy AMBI-1.gcode+AMBI-2.gcode+AMBI-3.gcode AMBI-auto.gcode
;)
Good solution - I would need to let my printbed cool down though, sice I use a FilaPrint surface, which sticks like crazy to PLA over 40°C
Yea, as is it's definitely only going to be successful for certain prints and printers
@@make.anything Have you ever seen these modded printers with 'infinite' surfaces?
Be really careful about wire brushes around the heater, usually there's a tiny gap between the cartridge and the insulation, it develops over time perhaps, it may short out and or short to your therm sensor, ( found this out the hard way), I usually avoid the wired side it's tough to keep them sealed with all the thermal cycling I guess. But just something to think about if this type of setup is unattended
I didn't consider that, good call!
If you get serious with production you could print your own mods. I love this hobby.
Nice. You might be able to reduce the between-print pause (and resultant blobs) by removing the wait-for-temperature command at the start of the 2nd and beyond prints. Even if the printer is already at the correct temperature it will wait for a few seconds for the temperature anyway. For people comfortable using the command line, the "cat" terminal command can be used to concatenate the files. "cat AMBI-1.gcode AMBI-2.gcode AMBI-3.gcode > AMBI-auto.gcode", or, fancier, "cat AMBI-?.gcode > AMBI-auto.gcode"
Have you tried folding thicker paper into a triangle shape pattern and adding it instead of the plain paper? This could be fixed on two sides and gives a stable base for the finished parts to travel on. At least these are used on CNC’s to keep shavings off of the linear guides
I did this for my d&d miniatures. They print much better one at a time.
Just found this video. Thank you so much for it. I have an application for shallow parts that may need a scraper like you mentioned.
@Make Anything great video!!! Have you tried sticking a mount where the googly eyes stickers are to push the 3D parts further out on the paper?
I like your Idea. Maybe a little bit mechanical updates are needed but ... nice! ... But you only can do that with the glas-plate. And if you wait until the plate is cooled down than you can also remove bigger parts automaticly from the built plate.
My i3 Mega S arrives today! Guess I'm running out for googly eyes.
This is exactly what I was looking for. I'd like to be able to run Octoprint on an Android phone and print off multiple objects while out of town. Them just come home and pick up and clean all the printed pieces. I've been doing a lot of mods and upgrades to my JG Aurora A5, and I've removed the "3d Printer" nameplate off of the gantry, I guess I could design and print a scraper/pusher that attaches in the same place.
