General Mach Discussion / Newbee limit switch false trigger problem
« on: October 08, 2013, 10:21:56 PM »
I am having false triggers with the limit switches.
I have 6 switches, 2 on each axis wired in series. They are wired normally closed. So they are grounded when they are inactive.
Each of the switch functions normally when tested manually on the diagnostic page.
As soon as i enable the limit switches, the Mach3 flashes error "Limit switch triggered" and wont jog.
The diagnostic page has none of the limits lit.
The inputs are normally grounded, the motors are not running, the debounce is set to 1000x40us, i dont think there can be any noise.
What am i doing wrong ? i have attached the xml.
Please help i am stuck.
