Apologies if this isn't the right forum. I sometimes have to stop a job in progress for whatever reason (broken bit, driver overheated, I need to go grab more beer, etc. ) I know EstlCAM will let you resume a job from where it left off, even if you have to reload the file. I haven't seen any way to do this in UGS. Earlier today, my X axis missed a few steps. I really just needed to rehome the machine, then have it go back to where it was and resume. Instead, I had to open up Fusion, modify the stock to take into the account the 1/2" of material that had already been removed, re-export the CAM and start over. (The alternative was watching it run around cutting air for an hour.) That sort of thing is not entertaining. Any suggestions?
