This morning as we were running the laser, my operator informed me that we have had a collision with a part that popped up, when he went to clear the error to get the laser operational again, he got a (07130050) - Position controller of axis 1 not active and a (00016904) - program control; action start program execution (program) not allowed in current state, we've had this problem before, and found out it was a line that popped off, this time around, i do not see or hear any leaks coming from the head it's self, would love some feed back on what may be causing these errors, or if any of you guys have had this error, and what you guys did to remedy the issue.
