Limit switch’s ?

Ok everything was working fine ,and all of a sudden my limit switches don’t respond.
I use alt-I and the switches are green lit, but when I home the machine they don’t stop it and over travel now.
If I manually trip them ,the lights stay green.the only one working is the e-stop switch.
First time I powered on the machine in 2 weeks,and worked perfect then.
Went into the wizard and put them to NC and reboot and then the lights are showing red.

Is there any parameter setting that could change it?
Is there a away to reboot to factory settings?
I’ve checked wiring and voltages,and is good.
I’m thinking ,a software issue.
Thanks for any help

Connect a wire to "com". Touch the terminals on those inputs one at a time while monitoring their state on the live PLC monitor (alt +I). If the state of the input changes when touched, you have wiring or switch problems

I checked and there all good,so I powered down and left alone.
Now I restart and get this screen that says -Axis are cleared but. Have 9031 drive fault.
And nothing works, and cannot home the machine. Shut down and Cycled power several times.
At one point I got a screen msg saying the software was excited and hit reset.
Nothing in the wiring or hardware has changed. I have been using this on a small mill cutting aluminum
For awhile now. I have the intel NUC ,and nothing but cnc12 software on it.
I’m ready to reinstall The cnc12 software,
I need to know after I uninstall it through windows,is there any files and directories I need to manually delete?
Seems a lot of people are saying there’s some bugs in the software and there’s a new release on the way?
As for the homing switches, I have proximity switches now. But have roller contact switches being delivered today.
Thanks for any help and insight on what could be wrong.

Which input do you have assigned to DriveFault? Do an Alt-I and see your input status to see if it reveals anything.

Open up your Wizard and look at your input assignments. You have assigned DriveFault to one of your input pins. If you don't actually have a drive fault input make sure you make that as unassigned or just as INPUT-X.

Are you using limits on all 4 axes? You have a NC driveOK (NC) on input 5. You need to set you inputs that are not being used to unused. You must also set the switch states to reflect what they actually are.

All your problems are shown on your picture

This is the perfect example of why a report is requested. It should be mandatory when posting machine issues.

POST A CURRENT REPORT ALONG WITH YOUR PROBLEMS!!!

Ok , ill try and find a report to send , but tell me why it has changed ? I didnt change it since the day I set it up
So that leaves me to think after windows boots up and the software finds a corrupt file and reverts to a backup file on the operating system . Thus software is as buggy as Mach 3 was. And it al comes down to the base operating system ( windows ) . Thanks for all the help from all of you .

Doc1,
The software actually works correctly. You have something setup wrong. Trust me when you get this running you will love it. The machine does exactly what you tell it to do if you setup things correctly. Mach3 would go off and do things totally unexpectedly. I spent years using Mach3/Mach4 and it really should get credit for launching the hobby CNC industry. Before it was around you really had nothing available. It launch things like LinuxCNC and a host of others. Art was a man ahead of the times.
