Solutions to ugly layer lines

Sovol SV06 Fully Open Source 3D Printer

Hey everyone, I thought I’d share my solutions/causes to the ugly layer lines on my Sovol SV06 Plus as I have read in many places people have some similar issues.

The biggest and easiest way to improve the quality for me is to ensure the printer is under good maintenance by making sure:

  1. There is sufficient machine lube (big improvement on my end as I forgot to apply fresh lube after buying the printer lol).
  2. Ensure the bed screws are tightened (they might have come loose, minor improvement).
  3. Ensure the Z-Axis frame is secure and all screws are very tight but don’t destroy the threads! (big improvement as some of my screws were a bit loose).
  4. I have also noticed dampening the overall vibration onto the frame has improved my quality by reinforcing the frame and again tightening the screws.

Finally If you are using the filament sensor I noticed some filaments have a bit of resistance going through it which resulted in a line appearing around every 5-10 layers.
My solution is to increase the diameter of the sensor hole and that way my filament gets pulled through with minimal resistance. I tested this after with 3 samples and the lines were gone.

Now my printer works very well and every print I do is in 0.2mm height with PLA+ filament.
Anyways best of luck! :slight_smile:

Yeh, the SV06 plus uses a Vocano hot end. They don’t call it a Vocano for nothing. In order to print correctly the Vocano needs to print very fast. In order to print correctly, you will need to run through a lot of calibration and tuning steps. A few notes to keep in mind: * The retraction setting can never be more than 0.5mm I would recomend 0.4mm to be safe. * The printer will probably end up printing way faster than any recomended settings. * Two recommened mods: Increase the size of the extruder cooling fan https://www.youtube.com/watch?v=qRBOeyudl58&list=PLV3fxzgNDX7z7odBQnNVRtzJxAlOKHUN5&index=1, and the y axis stepper motor. I don’t know of any video on how to upgrade the y axis motor, but it just requires removing the old one and bolting in the new one. I would recomend a 40mm thick motor. I think the stock one is 34mm thick.
