I am unable to set origin on the machine. The only way I can get a print done is to start from current coordinates. No matter where I set the origin LighBurn tries to go to an origin that is off the work area cashing my machine to crash into the rails. I have an xcarve with x controller. I have uninstalled LightBurn and re flashed GRBL on my machine. It works fine with any other software. What could I be doing wrong?

Start by having a look here:

# Common Grbl setups
If you have a GCode-based system, like a Shapeoko, Eleksmaker, X-Carve, or Acro system, you might need to make some simple changes to get the most from LightBurn.
#### Short version:
- You might need to adjust your spindle max RPM value ($30) to match the LightBurn default (1000) or vice versa. The value in LightBurn is called "S-Value Max", in the [Device Settings](DeviceSettings.md#s-value-max).
- You might need to enable "Laser Mode" if you have GRBL 1.1f or later (\$32=1).
- If your machine uses negative workspace coordinates you'll need to apply a workspace offset (G10 L2 P1 xx yy) and set your machine status reporting to be relative to the workspace origin, not the machine origin (\$10=0).
#### Grbl Flavors
Grbl firmware was originally designed for CNC machines and 3D printers, with laser support added more recently. It is highly configurable, and this is both a blessing and a curse. The "standard" way a CNC machine is configured is somewhat different than the way laser machines often are. Luckily this is easy to change, and easy to switch from one to the other.

I should have included I have been using the software for about 2 months without any issue. This is a recent occurrence. Before it worked perfectly.

Ok, I would still recommend verifying that you have the options set as described in that article.
