I have a 3018CNC that when I go to cut, moves left and triggers the limit switch.
It used to work right, but I haven’t touched it in about a year and I think I may have messed up the settings possibly. I’ve attached the readout for $$ and $# to get as much info up front as possible.
Any help would be appreciated.

Back in the day when I was running a 3018 Pro, I had a similar problem and it turned out to be an offset (don’t know how it got there) but I think this may be your problem:
$#
[G54:-290.000,-180.000,-43.460]
After doing some research I found this from Oz (his response in quotes) and it may, I stress may, be the solution to your problem. I’m no expert at this, but it worked for me. I hope this helps.
Most of the 3018’s I see don’t have homing switches, so they’re usually manually homed, and power cycling resets the machine origin to the current location of the head.
In your case the problem is that you have a workspace offset configured, which is common when working with CNC software.
Type this command in the console to see your workspace offset values (and press enter):
$#
You should see a few lines, with the first (G54) having values other than zero. If you type this line in the console and press enter, it will clear the offset:
G10 L2 P1 X0 Y0
That assigns an offset of X0 Y0 to the primary workspace coordinate (G54). Using the $# command again should show it zeroed out, and the ‘Get Positions’ button should report correctly after that."
My machine works in a negative workspace which I thought I had corrected by running G10 L2 X-290 Y-180. By running G10 L2 P1 X0 Y0 that I believe I have reverted it to a negative workspace.
[G54:0.000,0.000,0.000]
You’re welcome, I started out with a 3018 Pro and it can be a challenge, as it is a CNC machine at heart. I don’t know if you’ve read this portion of the Lightburn documentation, but it might provide some insight into what’s going on. Common GRBL/GCode Setups - LightBurn Software Documentation
