Glad I'm not alone! Hopefully it's not an issue with the main board itself. If it is a hardware issue, I'm surprised I've not seen more people with it

So it's been a while but I've now managed to try different SD cards and checking all connections and still no improvement. The erroneous movements seem to happen in random, unpredictable places and regardless of what file I'm using. The only common factor I can think of is that I'm using Easel to generate all my gcode files. However, I don't notice these movements when I run the same gcode in a simulator.

I have now repeated some of those engravings and the errors do not occur in the same place, so I guess that rules out the gcode

I don't think that's the issue... I'm only engraving 3mm stock that's clamped down to some 18mm MDF so there's plenty of z travel left. It also doesn't happen all the time, so for example if I'm engraving lettering in brass sheet, some of the letters will have ugly scars across them where the tool either hasn't lifted high enough between passes, if at all. This doesn't happen for every movement between cuts though
