Re: [CAD_CAM_EDM_DRO] Basic G-Code Question

Daniel:

The code should be fine. The redundant use of the codes for axis already
in position should not matter, but many implementations vary in slight ways.
You might want to report this to the author of the program as a bug report.
He will probably thank you for the input and make up a repair on the next
version.

Good luck,
