Weird Printing on Prusa MK3 clone
I have a Prusa I3 clone which I have recently upgraded to 24V. It is now printing strangely. Every 6mm or so in Z it performs a ridge. I have no z wobble although I did change my Z threads to 2mm lead.
Any help would be much appreciated.

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.
