Hello,
I have a simple program which should do 22 holes for a battery cover (see attached). Simulation (in Solidworks) looks good and also other G-code viewers show no problems. When I load the file to UCCNC v1.2111 it looks good in the toolpath view but when I execute the code, it misses the third hole (line N160) even though it is exactly the same as all the other holes. This happens reproducibly and the actual machine of course does the same. To make it more interesting, the last hole is being done two times.
If I leave holes out from the design, the behavior repeats with different holes. I have had designs with holes before but haven't had this problem. I can't figure out what's wrong
