We are running some parts in production, two sided machining, trying to figure out how to have wincnc run the second side immediately after the first automatically (two separate files) or at least have WinCNC call up the other file and just be able to hit enter to run it. Trying to speed up and not have to go to the PC and load each file manually. The WinCNC manual for M98 and M98.1 dont shed much light but Im pretty slow on the uptake with a lot of this stuff. (and cautious).
