I was working with my Ortur LM2 trying to engrave metal, failing each time. But I was able to engrave wood, and plastic. I unplugged my laptop for the night, plugged it back in today and now I get alarm 9 homing failure. I didnt touch settings and the wiring is the way I left it last night. Any suggestions? I tried resetting, power cycling changing USB ports, trying lasrgrbl then back to lightburn, it will not home. I am new at this so I am probably doing something stupid, however I am baffled that it was working fine and now it is not. I get the code below. Any help is appreciated. Thank you in advance.

UPDATE
Problem solved. Surge guard was turned off by someone. Even when off the power button will light up and the device will connect. I am guessing this is from USB power?
