I'm having trouble with the robot arm on our DT20. The arm works fine, but when I hit reset the machine releases air and then it won't work the next time I try it. I have to manually extend and retract then extend before it will work again. As long as I don't hit reset it will continue to work. The problem is when you get to the end of the program the machine resets and then it won't work on the next part. We don't have a robot loading the first side so I can't continue otherwise that would work. Any help or input would be nice. Thanks in advance.
