Last rapid movment plows through the material

I know that if the cnc doesn’t do what I want, it’s not the machine that’s stupid, but now I haven’t been able to figure out what I messed up.

During the last rapid movement, when the cnc returns to the starting point, it does not raise itself to the set original safety height. Of course, this will plow through the material or break the bit.

I tried many things:

  • firmware update
  • adding a new machine
  • z probe calibration
  • checking belts
  • checking bearings
  • higher origin safety height setting

But it didn’t solve the problem.

Any ideas?


For me having run the router into a steel hold down on my very first try, eventually I tried EDIT MACHINE
then Set origin height to 2 inches, been working fine ever since. But I suspect you already tried that.

I didn’t have this problem before, with the original safety height. When I set it to this, I didn’t raise it that high, but then I’ll give it a try.
