My apologies for posting a SS related question in the general forum but I was afraid with the limited traffic in the SS forum my post there might get overlooked and I need to turn a bunch of parts tommorow.
I installed a smooth stepper board yesterday and have almost everything up and working nicely, but since the instal Mach will no longer communicate wuth the PLC that operates my tool changer . What do I need to look at or change to get Mach to communicate with the PLC?
