Waviness over XY
Posted: Fri Dec 27, 2019 5:16 pm
Hello!
Recently acquired a Geeetech A20M printer
I tried to print PLA with plastic from the kit, more or less
Now I switched to PETG plastic, and wavy lines appeared upward on the calibration cat. On the last upper layers it is not.
The photo is hard to see, but there are such waves on all 4 side surfaces.
What could be the reason? (I assume that perhaps a high speed of 60mm/s, or the defect has a mechanical cause)
A little later I will try to print at a slightly slower speed.
In general - the quality seems to be good
P.S. sorry for my English

Hi, You can check if your z-axis fixing plate is loose and you can tighten it.
