OK Gene, I was not saying the sim was totally useless but it still sucks That comment was not supposed to be a detailed technical appraisal.You did not agree with me. The simulator serves a very useful purpose.
@tigermm, thanks for the file, the four hole would have done as well but I want to see exactly what you are seeing not a verbal description. I wanted to see how you were getting z=0.
The file you provided above does not seem to have a drilling operation in it. Could you please provide a file showing the issue you are reporting , so that I can try to reproduce and debug it?
G81 and G83 get a retraction parameter R which seems to be set by Start Depth . If I add a drill op to your model , without drill cycle treatment in grbl-post, it still fails to lift to safe/clearance height between holes. It seems the clearance move happens AFTER the G0 XY move !
