I’m trying to figure out a strange print defect on my Sovol SV08 and would really appreciate any ideas.
What I’m seeing:
On one side of a calibration cube, there is a very clear repeating vertical banding pattern
The spacing between bands is about ~1 mm
It looks like layers alternate: one slightly shifted inward, the next outward (sometimes 1 in / 2 out pattern)
The pattern is very consistent and runs strictly vertical
Other sides of the cube look much better or almost unaffected
Current Klipper settings:
microsteps: 16
interpolate: True
run_current: 1.5
stealthchop_threshold: 0 (so using spreadCycle)
What I’m wondering:
Could interpolate: True cause this kind of pattern?
Is this a known issue on the SV08?
What else should I check — either in Klipper or slicer settings
My first thoughts were something like mechanical periodic error (belt, pulley, motor), but the pattern is so clean and consistent that I’m not 100% sure.
Any suggestions or similar experiences would be really helpful
The front side is smooth and the opposite side is parallel to the X-axis, while the side parallel to the Y-axis has a defect on both sides. As a result, the front and back sides of the model are smooth, while the right and left sides have a defect. The perimeter was printed in one pass.
I also noticed that when I manually move the y-beam, the carriage moves a small distance along the x-axis. Is this the root of the problem, and if so, what are some solutions or areas to explore?
Is it possible that a cooling defect could cause such a specific time interval? It can be seen that the defect appears along one axis, and in the photo, the Y-axis side with the defect is on the right, while the X-axis side on the left is parallel to the X-axis and appears to be in better condition.
