I had this alarm before and was caused by magnetic interference which I resolved moving the routers cable away from the other cables and installed an EMI filter and made sure nothing but the Blackbox 32 is connected to that outlet. This error I can't clear and was after I changed the Z speed to lower speed, started with error 8 but now is stuck with the number 1, so I do messed up the GBRL code for sure and I'm surprised since I copied from my masuter pro before and was working. What I got: Masuter pro with extending bed, blackbox32 and interface. Also on $23 I have no idea if the switches should be min or max.

Load up one of our profiles as a base (CONTROL > Grbl Settings tab > Select machine from dropdown). Custom or nearest similar machine. Save and reset. Then go back in and change only relevant settings based off your old machine settings. Some default settings should not be changed
Last night I decided to go back and mess around with the machine again and I found the backup file from the gbrl and was working again, now I have a few backups just in case, also I figured out why I had problems before that made me change the gbrl - on my vcarve software for some reason I Z 3.5” above material so before starting the Z axis was going up triggering the limit switch. As usual was user error.
