Hi, yes, there are a number of ways to monitor any Hal pin. Hal meter, Hal scope, and configuration all in the machine menu. Or the Status display should show that as well. I find Hal scope probably the handiest because once it's set up, it remembers what you were looking at before rebooting EMC2. I hope that's what you were asking. Otherwise are the switches all on the same pin? Are all axis homing at the same time? The configuration files look all the same?
