Not sure if you're still looking for help on this one.
On your last line on your Mazatrol program there should be an option to continue or not. Can't remember the exact wording now. Will have to look when I get back to work on monday.
Not sure if the T1 had that or not. Never ran a T1. The T32 and newer has it. Was this robot a Mazak gantry or an aftermarket one??
Could have been that the robot was starting it. We have an Okuma with a robot on it. Robot waits for the M02 and then does it's thing. Shuts the door, waits for the signal and cycle starts it.
