We just purchased a MacTurn 50 from an auction and I am having trouble figuring out how to work the ATC. If I go in the parameters and activate the manual mode, I can run through the entire tool change process but when I try to do a tool change in a program it stops at the M06 and eventually throws a time out alarm. I tried running programs that were in the machine from the previous owners of the machine and I also tried writing sample programs using examples from the book but with no luck. Any help would be greatly appreciated.
