Hi, I am new here and a pretty beginner with CNC and I have a problem with my board Mach3 USB Motion Card (BSMCEO4U-PP) setting up the home limits switch with error ( This is only for the printer port modes ) when I want to activate the limits switch on Automated Setup of Inputs. I believe I have made some settings that don't allow me to make any change. Please help if is possible. Thanks

The ports and pins settings for inputs are for machines using a parallel port. They are not used with that USB control card. That is why you get that error message.

Here is a schematic of how to wire that card. The limits switch connections are shown on the lower left of the drawing. Limits use IN2 and homing uses IN3. IN1 is for the E-Stop and IN4 is for a touch plate.

Maybe the Admins could transfer this query to the CNC section?
