I was cutting a project and used the drill function the other day. It was a simple drill in steps and move to the next hole. The holes were spaced about 10” apart. When each hole was completed the z axis was raised and the sled began to move. However two things happened. The z move didn’t raise to clear the material completely before it began the horizontal movement cutting between a 1/10 to 1/4“ slot in the material and it continued to raise until it reached the next drill point. Four holes, four streaks.
Drilling is the only time I have seen this behavior. I’ve not had this happen when performing cuts to create separate pieces. Has anyone else had this happen? If so what was your solution? In the meantime I’m not going to perform any more drilling.

I looked at the gcode and even added a pause (G4) using P, X, and U and none of them worked. Is G4 used in GRBL? 4 wheels, 4 tests.
