Hi

Many thanks for coming back.


I have 1629.84 set and the object seems to print the correct height. It doesn't bind anywhere up the z axis or wobble.
I spent some time upgrading to the latest Marlin Bugfix 2.0 yesterday to no effect. I even changed PSU to a spare 24v 360W.

Tried printing in 0.3 and 0.2mm, the 0.2mm has ridges at around 3mm spacing except for the top.

For Reference I am using Mattercontrol, PLA

I am next going to try printing from another app and slicer and try and see if it is the firmware.
