SOLVOL SHOULD PUT YOU ON THEIR PAYROLL. Your Sovol videos are fantastic. I can't imagine trying to tackle my soon to arrive SV08 without your help. You are now my "go to" guy for anything Sovol.
10:25 i did my electrical engineering senior design project on this. ADAPT We created parametric design for equally dividing existing heater beds, create an aftermarket drop-in replacement. we did the ender 6 and it worked.
From what I understood from other reviewers Sovol should be using the load-cell at the back before each print to do the bed leveling (just like Voron)., and not rely the induction probe. That should be used only for gantry-leveling.
Basically the Kipper print start macro from Voron needs to be copied to the sv08 so that both the load cell and the nozzle cleaning brush get used correctly.
Yes, that should be researched. Afaik those who looked into this found the load cell to be less reliable than the inductive probe. Both can be easily replaced with higher quality ones, I think I will replace the probe first, as you could see, the M12 used in my T300 (and other 2 printers as well) produced 3× smaller range between samples: 0.0075 vs 0.0206. An M12 probe costs like $10 (but I already have a spare)
Thank you so much! These are the details of the printer I was hoping to see in other videos.
Looking forward to the probe upgrade :)
I have mine on a 24"x24" 3/4" slate stone. It fits perfectly. I have all my printers on heavy pavers of one kind or another.
That helps for input shaping
Örülök hogy egyre többen vannak magyarok is a youtube 3D nyomtatós közösségében, akik nem csak a consumer felhasználókhoz szólnak hanem azokhoz akik profi szinten szeretnék űzni ezt a hobbit.
Köszönöm, a remek videókat a nyomtatóval kapcsolatban. Remélem hamarosan megérkezik az általam rendelt masina és én is elmélyülhetek a fejlesztések végtelen lehetőségeiben.
A hosszú távú tervem, hogy egy toolchanger rendszert alakítok ki rajta. Nagyon szeretem a multi-material nyomtatásokat, a Bambulab X1-esemen sok színes modellt nyomtatok, viszont annak a rendszernek az a hátránya, hogy rengeteg hulladék keletkezik. Ennek szeretnék alternatívát adni és egy ilyen nyílt forráskódú nyomtató pont jó alap lehet.
Csak így tovább!
I'd also like to try multi-color printing, and the waste of AMS really holds me back from even adding an ERCF. I am curious about your toolchanger update, please keep us posted! (A többszínű nyomtatásba én is szívesen belekóstolnék, és valóban az AMS pazarlása tart vissza akár egy ERCF hozzáadásától is. Kíváncsi vagyok mire jutsz egy toolchanger update-el!)
@@gerGoPrint3D 'Teaching tech' channel is also making a video series about tool changer on SV08
@@winandd8649 Yes, I've watched part 1. Curious how the project will work out. He still has a long way to go...
@@gerGoPrint3D Agree, but I'm confident he'll come up with a working plan and that everything will be very nicely documented, both hardware wise as Klipper changes
@@winandd8649 Don't get me wrong, I love his content and will be following this project especially closely! I might even do it after him.
Great video! Please give us an update on the probing accuracy with the new M12 probe, as well as the sound dB with your upgraded quieter fan when they arrive. Looking forward to your future testing!
I personally done the M12 probe upgrade. Significantly better. Significantly more consistent. I am still however thinking that a mechanical probe is likely more reliable. The klicky. Anything electronic will always be prone to heat effected variance. But in all honesty, it means almost nothing for a 3D printer. A fraction of a hair diameter won't have much negative effect.
Filament shrinkage depends on the filament, so should be handled in the slicer settings for that filament.
thank you for doing what the manufacturer wont
I am a fan, that's the problem 🙃
You are amazing and this channel is the best. Thank you for your answer and all the work you are doing for the community. Your response time is out of this world!...lol.
Looking forward to seeing how much better the bigger probe will be. Also, how easy would it be to add a second Camera to the SV08, preferably a second one of the same type that came with the printer? Lastly, will you be looking into the AMS system that was Announced for the SV08?
Been loving my SV07+ so far and all your videos have helped a lot. Been getting a lot of good prints off of my Printer. I am excited to see how the SV08 develops with time.
There are two free USB ports on the side and even a third free port internally (and of course you can connect more via USB hubs). However I am not sure if the RPi would be powerful enough to drive multiple of these cameras. Also, if you want to place it too on the moving gantry, you would have to mimic the same cable route. Why do you need more than one camera? The current one is really wide angle, covers the whole print bed area.
@@gerGoPrint3D I'd love to see a "clicky" type probe. Lighter and more accurate, I suppose.
@@pizzablender Look into Nadir's mod, I show it at 5:12
Excellent, in depth and precision delivery of pertinent information!
I have a question... I noticed the connector for the inductive probe is labelled with 'BL Touch'. Do you think it would therefore be as easy as plugging a bl touch into that port on the print head and slightly reconfiguring the config file?
Anyway, I enjoyed your video and sensible approach to testing and assessing this new equipment.
Thanks for the awesome content! Keep up the great work!
I can't wait for your probe upgrade!
Great video again. Thank you so much for all the SV08 videos!
I'd like to see you upgrade the tool head. Would be nice to have an E3D revo hotend.
Thank you, looking forward for getting my SV08!
one NEVER changes ratation distance to get accurate parts as that will most deffently leave you with parts thats not accurate as insted of 100mm travel you would get 101mm or similar.
what you change is in the slicer xy compasation or in the printer firmware as its material schrinkage
Thank you for comfirming this, I had the feeling :)
You also calibrate e steps without the nozzle installed, cause you can have different melting rates for different filaments. You calibrate the flow for each filament.
Great video, thanks for your work!
Great topic, thanks 👍
excellent just excellent...thanks for all the specs!! built a very sturdy workbench she ready!!
You can cheat the width and height requirements a bit if you rearrange the spool a bit
@@gerGoPrint3D wonder if you can mount the spool on the opposite upper rail?
Burning *after midnight oil* 😊... and enjoying❤
Cheers gerGo!
If you calibrate the axis using different filaments, does that change the results of the test? One would think that shrinkage could be a factor.
Indeed, filament specific shrinkage does impact dimensional accuracy, and this isn’t something that can be offset simply by taking internal and external measurements. It seems we might need to measure the travel distances instead. However, if you consistently use the same type of filament, you could potentially calibrate your printer to achieve greater precision with that specific filament
@@gerGoPrint3D perhaps using a dial indicator and jogging the gantry a set distance might be a better method. Then you can add offsets to each filament type
I ordered and M12 probe from Sovol in anticipation of modding the SV08 to use it. It was $9.99 USD shipping incl.
That's smart!
@@gerGoPrint3D I used the super pinda from prusa on my sovol SV06 and SVO6 plus and will also do the same on the SV08, which is still accurate
Would this better M12 probe be installed from the factory in future versions? I don’t get why they use a lower quality one in SV08, than the ones used in SV06/07?
@@andersnielsen4390 Good point… I think they were optimizing for weight, but a 3x worse accuracy isn’t worth the 10-15g shed
@@gerGoPrint3D oh yes, weight saving, that would make sense. They could maybe make a “skeleton-like” printerhead casing in stead, in order to save some grams?
My SV08 finally arrived, when I ordered I thought it would arrive a week later, three months later I received the printer. I watched a video where the nozzle worked loose causing the nozzle to embed into the plate, couldn't the height of the nozzle be measured after the HOME function using the pressure sensor and moving the nozzle to the far right before testing the induction probe?
I know it looks scary, but afaik these are very isolated cases, and Sovol takes full responsibility they send you new nozzle and spring sheet asap. I have printed many many kilos of PETG between my SV08 and T300 (which uses the same type of nozzle, and I had this printer for more than half a year without any issues).
On the wiki page there is a firmware upgrade (.deb) link and an image file (.img) link. What is the difference, and do we need to use both? Are they one and same except the .img file is written directly to the EMMC instead of the .deb file which is used to flash it using the usb stick?
The DEB is for incrementally upgrade your current Klipper installation using a USB stick as shown in my video. This method retains some of your settings and your G-code files, timelapse videos. The IMG file needs an EMMC adapter, and the software BellenaEtcher to make a clean install overwriting everything on the EMMC card.
Thanks for the update on the wiki page being open now. I was able to download the content of the usb they ship with the machine and install the orca slicer profiles and read the user manual while I wait for my printer to ship. If anyone ordered a sv08 with the enclosure and/or the HDMI screen upgrade, I just received confirmation from sovol that the printer will ship first, then any upgrades as the become available.
Enjoy! Yes the upgrades will come probably weeks later. So mostly PLA and PETG printing first. But I've actually got used to using the mini screen, the printer is 100% functional without the HDMI screen.
@@gerGoPrint3D All I have on hand right now is PLA+ so it works out, lol. Looking forward to future videos, I have a feeling you are going to be a valuable source of tips and information.
How do we create the bed mesh you mention at 18:15 ?
You can use the "Calibrate" button on the "Heightmap" page of the web interface, or use the command Levelling > Bed Mesh on the device itself.
On my (old) Ender 5 plus upgraded quite a lot, I use Marling 2.1 trunk release and I switched to MPC instead of PID for hotend, it's so much more precise with nearly no overshot. Does klipper miss this?
Once tuned, I don't see much overshooting with the nozzle. The bed is trickier, but also less important to keep absolutely constant. Upon a quick search there seem to be some beginnings of an MPC option for Klipper, SV08 being open source nothing stops you from experimenting.
Hi GerGo! What is the bed thickness? Did they cheap out on it? If the bed deflection is consistent between heat cycles, you can shim it with aluminium foil.
The bed itself is pretty thin, it is only placed on a taller plastic raiser. But, as you can see in my video, it still produces very good flat mesh at 65°C, I see no reason to shim it or anything. It is plenty good out of the gate. The center 300x300 area could be well under 0.1mm range, having only the edges and corners sticking out (very minimally though)
@@gerGoPrint3D
I mean, if you see a dip in the mesh, you can place a single or folded piece of kitchen alu foil between the magnetic bed and the buildplate on that spot. It will stick to the magnetic sheet's plastic compound just enough to not slide around when removing prints, but it is easily removable if not needed.
It's not even a mod... Easily worth doing for nearly halving the 0,27mm.
Sad to hear about the thin bed. I was afraid of that.
gerGO, thanks for your wonderful videos! I have an out of place question here; my apologies! I have disturbed my print head probe position on my SV06 + printer while attempting to fix some filament oozing issues and don't know how to re-calibrate it to the bed. I have the Klipper screen installed and it is driving the nozzle into the PEI bed! Help! Thank you!
It's not that out of place. The same goes for any 3D printer. You just need to re-set z-offset. That when we establish the distance between the detected height by the probe and the tip of the nozzle. Make sure to raise the probe a little bit higher than the nozzle so it doesn't catch on things. Its bottom should be in line with the bottom of the fan shroud. Then set z-offset using the paper method. That's it!
If the probe bracket got damaged you can print a new one from the opensource STEP file on Sovol's GitHub page for the SV06+
@@gerGoPrint3D Thank you for your prompt response! I watch your channel faithfully, so keep up the good work!
That did the trick! Many thanks!🤗
Hmm. I did these calibrations but I am still off for some reason. Printed an object that has a hole for a 6mm magnet in it after the calibration and it doesnt fit. Wonder what else I need to do.
Adjust XY compensation for countour and holes on a per print (or even on a per-object) basis. Dimensional accuracy tests are more for testing and comparision to other printers rather than ways to adjust specific prints.
hello, it is possible to connect BIGTREETECH Smart Filament Sensor V2.0 ? that can also detect fillament not moving. (if motheboard can support it ? ) :)
There are a cuple of unused pins both on the extruder board and the main board, chances are you can install it either in place of the current one or directly on the extruder... But personally I don't have any experience with it yet.
Question, how are you printing the corner without support?
Oh, you mean in the cali-corner? Just proper design, 45° angles and 5mm bridging on the top. You don't need supports for these. My models almost never need supports, there are usually ways to avoid them.
Hey gerGO did you know that Linear rails for the Sovol SV07 Plus are coming out? see ( S&M Makers- RUclipsr). Will you be adding these to your SV07 plus? Dave.
No! I did not hear. I mean I've seen mods like this, but is this an official upgrade from Sovol? That would sure sound interesting
@@gerGoPrint3D YES! Sovol will be coming out with these shortly, Dave.
Hi Gergo,
I know you have tested a lot of 3D printers from Sovol. Which one would you recommend? I'm thinking of switching from my SV07 Plus.
The SV08 is a nice step ahead in terms of build volume without increasing the desk footprint (because of the stationary bed). The linear rails on all axes are also an upgrade from the v-slot wheels. Easier to enclose and is capable of even higher speeds. Cooling and noise is similar. Stock mini-screen is a step back, but it does accomplish the job, web-interface is identical and you can easily upgrade. Built in camera, especially with a non-moving bed is nice to have. Overall, it's about double the price but indeed at least double the offering. I keep using my SV07+, but the SV08 is now my first choice when printing something.
Hi gerGo, thanks for the great video. I just got my SV08 on Friday, and now I'm trying to follow your recommendations here. I could run the input shaper commands fine, but I'm running into trouble with the calibrate_shaper.py scripts.
When I enter the command as you have it posted, i.e.
~/klipper/scripts/calibrate_shaper.py /tmp/resonances_x_*.csv -o /home/sovol/printer_data/config/shaper_calibrate_x.png
the console just responds with 'Unknown command: "/" '. I feel like I'm missing something ridiculously easy here...
NEVER MIND! I somehow overlooked the 'ssh into the system' bit. *forhead slap*
@@kevanchapman5233 Thank you for posting the fix! Who would believe me, but I was going to ask you exactly this "have you logged into via SSH"? Enjoy the rest of the advanture!
Hi Gergo. Another excellent video. What I am winding is. Could 😂you offer these important improvements on a usb stick or combined with the usb coppieier. I think boy having all the upgraded files on the memory stick it would make it so much easier to install this. One other thind. I seen a ruzer and storage top available for download for the bamboo labels machines. This, I think, I think would be a super upgrade to have for the Solvol sv08.
Kindest regards.
Mike Skerritt.
PS. I have a Solvo sv08 on oeder since your first video and cant wait to start printing.
It's very easy to add these changes. It's really download, drag and drop and a single line. Maybe I will include the probe settings in my macro collection as well, then it's really a one stop affair. Having them on a server like cults3D is better, because I can keep it up-to-date. And if you ever download it, you will get automatic update emails if I make improvements in the future!
I know 3DPrintDemon is also coming out with his (even more powerful) macro collection, and who knows, I hope Christian Vick will also join in the fun with his Klipper Printer Additions. I hope he is gettin the SV08 as well. Imagine his preprint magic on the SV08!!! ruclips.net/video/R1-VU01-9Es/видео.html
Hey guys , I just received my device last week and from scratch, it showed the known z belt rattle issues but another one, that I've never heard of yet. First time I bootet up the device and the led strip and MCU fan were off and could not be started manually neither. After checking all the cables and consulting the Sovol support, I couldn't find any lose cables or so. All of a sudden, when I bootrt the machine 5 times, the led strip and fan turned on ?!?! So far so good, I did the calibration , first prints etc. The next day I tried to boot the machine again: same issue. No MCU fan , led strip shows as "on" in the screen menu and no chance to turn it on manually. I tried to do several factory resets but this didn't help. This is the current status until now; the machine works in kind of 1/10 tries. Any ideas ?
One of the beta tester's device did this sometimes. It’s actually quite dangerous as it allows the mainboard & Pi to severely overheat! He thinks it is due to a firmware issue on the board, or at least some code buried somewhere out of sight regarding the built in initial state behaviour of these pins.
Which is silly as it should be in the printer.cfg file!
It was mentioned to the engineers, hopefully they will fix it in an update soon.
There is no way to change this behaviour as a user as it needs to be done on Sovol’s end. Or the file where they hide these initial states can be found.
As far as I understand just power cycling the printer should fix it. But we haven't really been able to pinpoint what triggers this behaviour.
@@gerGoPrint3D I also receive these Moonraker update alerts , nog sure if this is also a know "issue"
Dependency: Moonraker
The current Moonraker version does not support all features of Mainsail. Update Moonraker to at least v0.8.0-306.
Never adjust X Y or Z stepping unless a progressive calibration shows it off in multiple length samples at a fixed rate of error
Thank you for comfirming what I too concluded by the end!
Thanks! Appreciate all your videos.... Cup o' tea on me ;)
Thank you so much for all your support!!!
Hey GerGo
Take a look at this video about calibration “cubes”.
ruclips.net/video/dbWAhb40kG4/видео.htmlsi=gspX9zk6vVmgmWV0
I downloaded his cauliflower and spreadsheet for a minimal cost. I used it on my SV06 and got good improvements. He also sends out updates for free. The latest was a change to the spreadsheet.
I think that this is a worthwhile step to take with any printer.
Good tip!
Just post the video, I found it in my RUclips feed as a "coming soon" and likely won't ever watch it because once it comes up in the feed once it doesn't come up again from my experience.
