Vertical ripples/horizontal lines/Z-banding
Hi everyone. I'm currently reprinting some parts of my VC4 using eSUN PA6-CF with a SiC nozzle.
I have some strange horizontal lines (vertical ripples). See picture. The peak distance is around 1mm. The lines are going around the complete part, so it's not an X or Y layer shift.
For me it looks like the flow for the outer perimeter is changing with height. (which cannot be IMHO)
I have redone PID for hotend, flow and PA is calibrated.
A calibration cube does not show those lines.
Any ideas what else to check or where the problem can be found?
