GRBL Alarm 8 Code - Homing Fail

CNC Machines
1

Just received my machine 2 weeks ago. I would not run so Carbide sent me a new controller and I was able to run 2 test jobs last weekend - everything was great until…

Tonight I go out to the shop as I need to get some wedding projects done this weekend and I get a GRBL Alarm 8 all of a sudden…what do I do. I am new to a CNC however since I have had this machine for 2 weeks I am continually having problems.

I would appreciate any help you can direct my way

There is a list of error codes at:

and for Error 8:

GRBL Alarm Code 8 - Homing fail

Pull off travel failed to clear limit switch. Carbide Motion does several checks to avoid this error so it is very rare in a Shapeoko or Nomad CNC machine.

and it has a link to:

https://my.carbide3d.com/docs/troubleshooting-homing/

for this.

I am not sure what you want me to do. This is pretty frustrating having all these problems in the only 2 weeks I have had the machine. Hopefully things get better.

I’m new to cnc as well. Just got started with my machine a few weeks ago. I sometimes get an error when I hit my limit switch, I am able to move back off the switch, causing a second alarm but it moves fine after resetting the second alarm.
In the beginning I had issues with hard and or soft limits causing issues, I turned them off and all is well so far.
I know there probably correct ways to fix this, but this is how I work around. I dont get an error when I home.
