hi chaps. I am running mach 3 to a mf70 mill. the mach 3 is showing the tool runs etc, and the x,y,z lines all show movement on the screen. but there is no movement at the mill. it was working yesterday, but I have been playing around with buttons to fix the first fault, which was the program jamming on tool change. the machine control card is the TB6560-based stepper. can anyone point out what I need to do, I don't think it is the hardware at fault, just the settings. is there a way to check these out, or is their a correct group of settings for the machine. thanks. michael
