SO i decided to start using the shapeoko 3 i bought years ago… and it started to not listen… when i was adjusting the z position it just started walking down the Y Axis… so is this a me thing, a shapeoko thing, a controller issue? it also then said something about serial port not found?
Probably EMI. (Could be a loose USB cable, might be a bad controller)
