You can still extrude, even if the nozzle is too close to the bed .... the probability of a clog is higher though. I think it only initially hits the bed on down movement. Maybe due to inertia of the mass .... it could be simply to fast ... But it would be pretty interesting to see more layers and not just the baselayers on the bed.
Impressive! Every time i hear that nozzle hit that platform I was in pain. Something about absolute zero. Something something closed loop rotary encoders! If not try to go slower next time. 40-60 speed
The length of the total way from the solid base to the nozzle tip makes this 3D printer a real challenge to do accurate modelling with usable repeatability. It will by the design be extremely sensitive to any vibration and slack in all moving joints. But it certainly is a rather interesting alternative to make you think different in design ideas
That should be easy to fix with some kind of acoustic or optical dynamic positioning system. Idk why you lot insist on relying on non-self-correcting precise part tolerances.
the practical benefit over conventional platform is in arm based platform it can do various task, just change the end-effector module/tools that suit your needs or job to be done.
im just confused when it drops the nozel on the part why isnt the part being broken in 100 pieces? u can clearly hear it smacking them layers... or was it something else making that noise?
Yes, Thats what I am looking for, also if you add infinity Z which mean the slicers do the job vertically instead of horizontal and moving based in a roller.
WOW WELL DONE, I TRANSFORMED MY PRUSA INTO A 3D ARM BUT I HAVENT FIGURED OUT THE CODE FOR IT. CAN YOU HELP OUT AND SHARE A MARLIN FILE THAT WOULD WORK ON MY GT2590 3 MOTOR SET UP.?
Nice! I've seen people throw around ideas for a printer like this, but haven't seen a working implementation until now. Is the tilt of the nozzle compensated for passively via a parallel link type arrangement of belts or is that actively driven as a fourth axis?
Interesting project. 7Did you try objects with more hight. Would be very interesting to see wall quality. Spacialy artifacts from vibrations and resonances.
Make the hotend rotate and you have a 4 axis 3D printer imagine the possibilities.... non planar printing on all sides for strange and amazing appearance
Hurts every time then nozzle hits a bed
Jokūbas Zareckas I assumed that was just the mechanisms clicking
Are you sure that is what is happening?
Looks that way to me too.
The agony .... 😬
that's the mechanics. if the nozzle was really hitting the bed that hard it would mean it's way too close to print and nothing would extrude.

@@thesebi I agree.

With several of these, parts from multiple materials could theoretically be formed. Neat.
i really like how you keep the head always vertical with only three steppers. Awesome project!

It's a mechanical trick!
Yup. It has a belt in yhe middle
Wow, this could enable non-horizontal layers.
Imagine this robot with continued carbon fiber filament. U could build literally ANYTHING with maximum strength. Making CNC obsolete.
@@INeedsMoneys well.. no
@@j.kihope Nah, the dude doesn't understand that literally every 3d printer is also a CNC.
@@INeedsMoneys 3D Printing is CNC. As long as you dont control the machine with a joystick ;D
@@j.kihope well. Ok u nazi.. it makes cnc machining obsolete.
Hey, are there plans?
Had this Idea a year ago and was thinking how to realise... You Made it, awesome. Good end for 2019 to have seen this. Good job!

I agree. But the weight of the large stepper should help dampen some if those vibrations
Felicitari.Foarte bun proiectul !!! Parca loveste putin extruderul de masa ,dar cred ca se poate remedia. Succes in continuare
Would love more detail on this project
@MichaelKingsfordGray ur 💩
@MichaelKingsfordGray Same with you, this is actually a pretty cool project, it will probably make a big difference in the future of 3d printing
Gabriel Bryson he’s just a troll on the internet
Maybe you can go in the direction of 5-axis cnc machines so it can print overhangs without support
This! 🔥🔥 + add continued carbon fiber filament.

This is awesome to look at as someone who is very into 3d printing
So is it possible to print in 360 degrees around itself? And can it print as tall as itself? Thanks
Yes, Thats what I am looking for, also if you add infinity Z which mean the slicers do the job vertically instead of horizontal and moving based in a roller.
Can you share more details about this project
Will you publish the source design? It's really cool.
Amazing build
This is your daily dose of Recommendation
Robotic arm the 3d printer
Amazing! Is the system open loop or closed one? If it is open how do you do homing for the arm ?
@@Synonym_MS no , what do you mean by microswitches?
@@karimmobarak2031 it homes at the beginning using limit switches. It's open loop
Super tare! Bravo!

Now for the next challenge use the robot arm to print another robot arm.
Doctor Ford aproves this. Like Bernard.
How did you modify the marlin firmware for this type of arm movement.
Nice! I've seen people throw around ideas for a printer like this, but haven't seen a working implementation until now. Is the tilt of the nozzle compensated for passively via a parallel link type arrangement of belts or is that actively driven as a fourth axis?
M-ar interesa și pe mine sa fac o imprimanta așa. Este super reușită felicitări. Sunteți dispus sa dați planurile de construcție? Mulțumesc
Отличная идея!
Great job! Marlin modified for IK on his own, or found in the public domain?
Nice arm robot design
Can you send me the research paper for this project?
How did you get the firmware for this thing to work? The kinematics are hard to think about
How did you modify Marlin for IK?
Can you provide more details about it if you cant so why you have uploaded it
Impressive work
Where is the difference from a usual Delta?
How did you mod your Ramps 1.4 for 3.3v?
Interesting project.
7Did you try objects with more hight. Would be very interesting to see wall quality. Spacialy artifacts from vibrations and resonances.
@MichaelKingsfordGray how do you? There are printers on robotarms out there. Of course industrial, but this one doesn't look to woobly
@MichaelKingsfordGray you re getting personal already... Ok cool.. That helps!
👏👏👏👏👏
This is the future of 3d printing. Support material will be a thing of the past.
How? Even this thing can't start printing in mid-air
Make the hotend rotate and you have a 4 axis 3D printer imagine the possibilities.... non planar printing on all sides for strange and amazing appearance
How do you program the arduino? can you share?
Mechanical vibrations are crazy in that thing
Sir, can you share the algorithm ?
More information, please
wow...that is one hell of a gear ratio at once step...why didnt u consider breaking down into multiple steps to make it smaller
Backlash might be quite large perhaps?
Fewer parts, less backlash, simpler design.
Amazing!!!
Super!
great, can you share the firware and connections
I think you should not attach extruder on arm
And what is this sound when head touches ground
But really great work i loved it
The inertia. It is the compromise for high speed.
Круть!
Layer height might be terrible though
Hanzhen harmonic drive gear , strain wave reducer, robot joint , over 30 years experience
Most excellent.
What that extruder do to you?
Sounds like it's just mashing the extruder on the level
You need a counter weight
Bravo, sunt mândru că ești român!!!
How about this resolution?
Bisaan, eta make firmware naon mang? Marlin lain? Scara?
Kumaha setup na?
Let me ask, what application are you using?
Marlin.
How to make te arm for 3D printed?
Bravo.
Did you marlin firmware
¡Excelente! :)
Crazy shit!
What are the max accelerations for this?
Nathaniel Iten really really low
What are using to make head always horizontal
Math
Same principle as in a desktop lamp - instead of rods, it is a belt.
Firmware files pls man you will help a lot of people
So much backlash and shaking. But ditto for the effort
Olá gostaria de ajuda tenho um projeto parecido
How much would it cost to buy one of these? If it gets sub $1000 im all for it!
$500 and im stacking these bitches
It is amazing
6 axis?
3
@@alfiolocatelli5093 it's 4 axis. Base, shoulder, elbow, wrist. 5 if you count E
@@tjuggernaut29 Oh strange, you can easily do the same thing with 3 steppers🧐
tjuggernaut29 i think its only 3steppers + extruder, i think the wrist is mechanical becasue its Always in the same orientation.
@@lilypower Yes, you're right
hi Ionel , why did you use arduino due? for the 32 bits?
why not a mks base?
Yes. Inverse kinematics needs a lot of calculations.
