General Mach Discussion / Pulling Pins High
« on: October 26, 2010, 08:35:27 AM »
Can someone explain to me why you would pull a pin high to +5v?
The reason I ask:
I'm trying to setup an auto zero for my Z-axis. I set the input to active low but when I run any script Mach never gets a signal to ground to trip the script. I'm going directly to the port, no BOB.
What's going on here?
I've seen a few setup this way but I don't know why.
