I was making some changes in my lighburn settings. When I tried to move the laser on the X axis, it mad a sudden jump and the I couldn’t get bit to move at all. After a couple of tries, the laser stopped moving on the Y axis. The Engineer with Universal Engravers said this is a homing problem and to push the $22 button (whatever that is?). All three stepper motors appear to be locked.
The $22 variable in grbl tells the controller if it needs to do a home operation on startup and that its a legal operation…
This can be enabled or disabled via the console or Edit → Machine setting. If you use the Machine settings, suggested, you can save the current copy of the configuration. Don’t forget to write the changes back to the controller.
In the console simply entering $22=1 enables homing, $22=0 to disable homing.
In simple terms it enables/disabled the homing operation.
Does it normally home on power up?
If so, is it moving towards the home switch locations?
After it powers up, can you talk to the machine?
