I am running an Ethernet smooth stepper with mach3, and from the smooth stepper to a Leadshine mx3660 driver ( drives all 3 of my motors). My question is, when assigning pins in mach3, does the driver have anything to do with that? The db25 ribbon goes from the Ethernet smooth stepper, to my mx3660. The smooth stepper has its own outputs for each pin, how do I know that it matches the mx3660. In other words, say I set up an e-stop using pin 9 for example off of the smooth stepper. From the smooth stepper pin 9 it would obviously connect to the drivers input pin 9. What if the input pin 9 corresponds to something else on the driver. Not sure if this makes sense, I'm definitely new at this and trying to figure it out. If anyone has any input that would be awesome. I attached a picture of my setup. It's temporary until I get it on the machine.
