Limit Switches working backwards
« on: April 13, 2007, 10:54:29 AM »
Limit switches are wired for NC all wired together. My problem is that I must push on the limit switch to get anything to work. I have changed the active high and low in the homing/limits and estop with no change. I have also tried the debouncing, no change.
My DRO's will show movement if I push any button but the table does not move.
I am willing to try anything.
Thanks,

OK, Loui

Under Config, Ports & Pins, Motor outputs, Have you assigned a Port # 1 to all Axises, Step/Dir Ports. Right side of window and Apply.

Same window, Changed the Dir/Step Low Active to different State.

Same window, Inputs Tab, Set up port Pins for your axises, changed the Active Low State.

Diagnostics Page should show switch activity when Pressed.

Take a Look, Chip
