Printed some nice drawers for my screws and nuts. Z-leveling is a pain as the two z-axes always get out of sync. I found a fix for the Tronxy X5SA https://www.thingiverse.com/thing:4297432 and adapted it for my setup: https://www.thingiverse.com/thing:4305634
The problems with octoprint may be fixed with a new plugin: https://plugins.octoprint.org/plugins/fixcbdfirmware/
The build plate is worn out, the coating peels off. I now print with a cooler heat bed and wait until it is cold, before I take the prints off. Hopefully the z-axis fix does bring a further relief.
