I'm just learning about EMC2 so please forgive me if this question has already been addressed elsewhere. I could not find any mention of it in the user manuals or email archives. I am converting to EMC2 from Mach3 software to control my 3 axis mill. Mach3 has a feature that prevents it from starting a new motion (forces it to pause) if one of the parallel port input pins is in a particular state. In my current system, I use a signal called "at speed" from my spindle controller (VFD) to drive that pin. It gives me a measure of confidence that the system will not try to start a cut if the spindle has not ramped up to speed or if it has encountered some error and stopped or slowed down. I would appreciate any guidance you could give me on how I could implement a similar feature using EMC2.
