Hmmm alarm 8 
Just installed end stop on a S9, but it won’t home, it doesn’t move just makes a quick sound and then “Alarm 8”
If I run the machine and activate the switches with my finger, the machine stop as I should.
Any suggestions?
I’ve done it on multiple other machines, but this is the first time I have seen this alarm
Show all the machine settings.
ALARM:8

If I disconnect the switches from the board and press “Home” it still gives me the same alarm
This alarm shows that the switches are recognized as pressed all the time. You might need to change the $5 value.
Go through this documentation: Limit Switches - Diode Laser Wiki
That did the trick 
Thanks for the help
