I can but g91 relates to absolute position. Rather than just going to the set 0 on z it’s trying to go to absolute 0 which is past the Homing switch. When that is triggered it kills the code as it’s a hard limit.
I was using the generic post processor but still had this issue. Do you have a g code file you can upload so I can take a look? I’m using one I installed a while back, I’ve only ran one test but very different g code.
I’m with you on replicating the CM functions, I’m slowly working on it. I just keep on reading up on g code to understand all the commands.
I updated to the latest UGCS platform this evening.
