I was recently running a job and in the middle of it UGS went in to HOLD. It happened on two different tool paths. I tried to resume but the machine cut where it should not have. Happily, and for the first time, both errors resulted in the mistakes happening in offcut areas of the project so I was able to recover.
Re-running the toolpath worked fine the second time. I wasn’t able to get a clear explanation of what would trigger a HOLD alarm on UGS. Can anyone provide any insight? Given that it ran fine a second time I’m guessing it’s a transient/static electricity or interference kind of thing typically?
