Input 4 error

Hey guys, I was doing an engraving cut with my PRT STD, I hit the space bar to stop the file and the machine acted funny, like it was thinking about the command, then it poops up with the Limit switch on input 4 is on, check and retry. Then it tells me the stop switch is on. I've rebooted the machine (control box) and restarted the computer to no avail. continue getting the same type of errors and the machine won't move.

I've had the happen before, but can't, for the life of me, remember what I did to fix it. Could it be my wireless keyboard?

Any ideas?????

Possibly a corrupted software setting, try resetting it with UR and follow the prompts.

Thanks Sxott, I'll give it a try.

Yea, no love there. and I looked back to the last time this happened, and tried the solution, still no love.

Any other suggestions?
