Thanks Jon - that is indeed the case, and everything is working now (with the default dip settings on that board even). > Actually, enable is not as critical in a stepper system, unless you have need > to move the machine while the stepper drives are powered. Much less likely to > have a damaging runaway with steppers. Gotcha. When I turn LinuxCNC Machine Power off the stepper stays on. Is there a pin I can connect that too to shut it off when I shut off the Machine Power?
