Rogue Limit Switch Error

I have LinucCNC 2.6.8 installed. I can get my setup to work without limits. When I set up the limits I am getting "Joint 0 (or 1, of both) on limit switch error" but when I check the status through the HAL functions,the limits are all FALSE.

Can this be caused by incorrect setup? Or incorrect jitter settings?

Limits X = Pin 11,Limit Y = Pin 13, Home X & Y = Pin 12, Home Z = Pin 10



Attached is a copy my .hal file.

It could very well be noise on the signals. You can probably get round this by using the "debounce" HAL component.
I have pretty much always needed to.

I had to use normally closed contacts on my limit switches to get rid of this error. Debounce didn't work for me. It seems like I am using 5v dc for the limit switches instead of 3.3v from the parallel port, it has been too long, I cant remember why, but I had to pull 5v from a usb port for something then invert some signals.

You should always use normally closed contacts for limit switches.

I am using NC switches. NO switches are just asking for a machine crash.
I will try the debounce function, sounds like that might resolve. given the inconsistent error I get.

I will also check the voltage.
