hi, I had a computer die a few months ago. I am trying to get back up and running on a new computer. I have linuxcnc 2.6.3 installed, but having some limit switch issues. when I start up in axis, I turn on and immediately there is a joint 0 and joint 2 limit switch error. The display shows the limit switch symbols lit up on the DRO for those 2 axes. pushing the limit switch causes the symbol to go away and if I keep the switch depressed I can turn on with no alerts until I release the switch.
Here is my hal file: pastebin.com/2FAFhwx3
Thanks, Paul

Sounds like the limit switch polarity changed (how, I dont know...)
so you may have to change:
so you may have to change:
net both-home-x <= parport.0.pin-12-in
net max-home-z <= parport.0.pin-15-in
to
net both-home-x <= parport.0.pin-12-in-not
net max-home-z <= parport.0.pin-15-in-notPlease Log in or Create an account to join the conversation.

Fixed it, had a few things going on - pins inverted and also had one switch wired to the wrong pin!
Thanks.
Thanks.
