I’m experiencing poor print quality using PLA. I’ve made all the adjustments with Orca Slicer, but the results aren’t optimal. What do you do in these cases? What do you suggest?
Best regards

I think I’m experiencing the same thing with my max and pla: printer and filament calibrated, but one side (always the side facing the Z1 rail) has this type of mechanical looking effect. I’ve checked the belts with a pro belt tensioner, and I’ve gone over the entire mechanical assembly to ensure everything is perfectly level and all screws tightened. Any advice? Bad stepper motor on the Z1? It’s definitely not the model or slicer, it occurs always facing the Z1, regardless of seam being turned or put on random, etc. Thank you for your help, driving me crazy!
Good morning,
yesterday I received an SV08 Max
,
Unfortunately, I am experiencing serious printing issues with PLA: even the Benchy file included in the machine’s memory prints very poorly.
Compared to the videos and reviews I have seen online, the print quality is nowhere near what I expected. The quality I am getting is simply not acceptable.
I am using OrcaSlicer with your official print profiles. I also tried reducing the print speeds, but this only led to a slight improvement, which is still far from sufficient.
I have already carried out the following checks and attempts:
-
checked and tightened all screws;
-
adjusted the belt tension following your tutorial;
-
replaced the nozzle;
-
updated the software.
Despite all these steps, the problem has not been resolved. The machine does print, but the quality is extremely poor.
I would like to know who I can contact for technical support.
Thank you in advance.
Kind regards,
Ravetta Davide

Hi, okay, thanks.
I’ve just tried disconnecting the filament from the external feeder, and it seems to work much better. Basically, when the filament goes directly from the spool to the print head, the situation improves noticeably.
Has anyone else already experienced this behavior?
Sorry, I can’t help you, I don’t own such a printer.
I tensioned it very accurately as you suggested (I got reliable with the tuner app), both sides, and I tried to make sure it’s not rubbing flanges of the idler as it moves around the bed. But I’m still getting this artifact. I keep checking the belt pathways and don’t see any places the belt is grinding or bumping into things it isn’t supposed to. This 45 degree cube shows it only occurs on that one orientation, the other faces are fine (not great z banding but it’s okay). Driving me up the wall, because I can’t print anything reliably.
I don’t own one either but if you’ll check older posts in this forum you’ll find many complaints and a couple solutions for buffer (feeder/pusher) issues. I don’t recall any surface finish issues.
Did you rerun input shaper tune after tensioning the belts? I run it at Z=25, Z=75, and Z=150. Large variance with increased gantry height indicates a structural issue.
Long shot but implement the PLR patch (PLR and ‘mcu’ shutdown: Move queue overflow). The existing PLR performs a file system write inside the motion planner. It is possible (but very unlikely) that is causing micro jitter on following the Z move.
Then try using “paint on seams” in the slicer. Paint them right down the middle of the bad side. This forces the printer to Stop in the middle and may give insight to resonance issues. Corner to corner could be informative too.
Lastly manage your expectations. Positional error is motor steps PLUS deflection. Deflection is calculated as a percentage of the length of the build axis. All things being equal a bigger printer can never match the precision of a smaller one.
Partial solution to the above is print slower… and even slower. Once you eliminate resonance effects and get baseline THEN start working on resonance prevention.
I checked the motion of the carriages and pulleys: the gantry seems to move smoothly and without any binding.
I also verified all fastenings, realigned and tensioned the belts multiple times following the official procedure, and even tried slightly lower and higher tension values, but without any improvement.
After each adjustment, I reran the input shaper. I also tried extending the frequency range beyond the rather restrictive values set by Sovol in the configuration file: I’m currently running it from 15 to 100 Hz, but the result does not change.
So I’m unable to understand where the issue might be coming from. I’m quite experienced with 3D printers and have been working with them for many years, but in this case I can’t identify the cause.
I decided to purchase this printer after watching numerous reviews online. None of them showed issues like the ones I am experiencing; on the contrary, the print quality in the videos looked very good.
I fully understand that we cannot expect the same quality as a 300×300 printer, but in this case the problems are evident and go beyond normal tolerance.
From what I’ve been reading, it seems that similar issues are mainly appearing on the latest machines delivered. This leads me to think there may be an underlying problem affecting recent production batches.
Personally, I believe it is more likely an electronic or configuration-related issue rather than a purely mechanical one.
Hello,
I recommend that you contact Sovol at info@sovol3d.com
Please include your order number and describe the problem.
They will respond within a week.

I contacted them yesterday, thanks. I’m waiting for their response.
Did you implement the PLR patch? As delivered it performs a file system write and waits for conformation from INSIDE the kinematic event scheduler which is KNOWN to cause timing problems.
The question remains - can you cause the defect to move to a different side by forcing the seam location. That would allow you to focus on Z moves and Z axis resinonce.
Are you using Z hop on retract? My gut feeling is the “flying gantry” is oscillating up and down following Z moves.
No, one of the first things I ruled out: it has nothing to do with seam placement or position on the bed - it occurs only in a specific orientation (the front and left of the bed), so it hints at purely mechanical and belt issue. But all three of us could all be talking about different issues?The layer lines are also not great, seams a lot of minor sources of vibration. But my main issue is the giant artifact that exists even after even and correct belt tensioning, I think maybe coming from a loose idler.
Yes, quadruple checked every single one of these screws and have taken it apart several times to make sure absolutely nothing missed.
Yes, brand new, and this is more or less the type of quality I’m seeing after all the calibrations and lots of hours.
