That’s definitely odd.
Can you do this:
File->Save gcode, save to a file with .txt extension, then upload the file here.
Also, can you test the jogging controls. Can you confirm that they work as expected? Up moves up, down moves down, left moves left, and right moves right?
ok it will do a basic rectangle.
yes all controls work normal.

This is interesting.
It says you’re using Current Position. Did you change from Absolute Coords?
If not, can you try toggling to Current Position and then back to Absolute Coords and try generating the file again?
no I didn’t, that’s what i am stumped on, it does home, toggles, frames correctly. when it comes time to start the project. it does some weird things.
Delete the device and recreate with the .lbdev file. Disable the pointer offset.
Then retry.
i did. still wanting to go to my left.
centered laser head in the middle of work piece. and center of work area. it was being told to jog to -14, -8 before it starting project after hitting start.
trying to find where it is being told to do complete that rule.
it looks like maybe a recalibration would fix it?
There’s no opportunity to do this for xTool machines.
Can you make sure you’re on Absolute Coords and then regenerate the gcode file please?
yes, will also be sending a separate video link for visual.

also to note, i do not have these issues in xcs.
video link for visual.
Update: I just turned off “optimize cut path” and the machine cut the outline cut path as ordered but did not engrave any fill lines. The head then proceeded to go way left to coordinates the send it out of bounds.

I am very sorry that I never replied, and I apologize if I miss a detail skimming through the recent replies.
In your first video, the crosshairs are still on, make sure to disable them in XCS first. These are my settings in XCS;
Having your positioning mode in “Red cross” likely causes the firmware built into the xtool to move that offset.
Second is a few discrepancies in your device settings for the XTool. Such as relative Z moves being on, there’s no Z control so there’s no reason for this to be enabled.
For reference, these are my settings;
I see you already disabled Auto Home on Start, which is good, that doesn’t work correctly and you should use $H in the console on start, or your header gcode (if you have a pro with limit switches and use absolute positioning).
Try matching similar to my settings in XCS and Lightburn (create a new device instead of overwriting your own for safety) and see if that works out better.
Also keep in mind, at least in my experience, the xtool requires you to work in metric for the final gcode. Every time I try something in inches, it doesn’t move or acts… stupid. Could be something on my end, but I digress. Easy enough to test by doing your entire project in imperial, then clicking the little button to the right of rotation to make it mm, then try.
This swaps the entire project to metric automagically. I mention this because in the last gcode you pasted, it’s trying to travel negative two trillion mm.
G0 X-2,147,483,648.Y210.177 Commas added for clarity for X movement.
EDIT: bounds are kind of ridiculous as well.
; Bounds: X164.45 Y168.28 to X-2147483648. Y-2147483648.
Makes me wonder if you have some sort of object in the vast beyond. Try clicking the dotted box in the toolbar, it should zoom out to show all the objects in the field and see if there’s something in the void.
EDIT2: Looking through a backplotter (ncviewer.com) indeed there’s something waaaaaay out there. First view shows your outline.
G0 travel lines… I had to zoom waaaaay out to get this;Is there some stray line or such in your file?
The good news is that the gcode is now reflecting the Absolute Coords. However, the values in the file are extremely far off.
This is the core of the issue.
Can you confirm that you’re using this lbdev file located on this page when creating the device:
Operate xTool D1 with LightBurn – xTool
Can you post an updated screenshot of Edit->Device Settings?
One other thing I’m beginning to suspect is that you may have a corrupt installation. Can you download and reinstall the latest version of LightBurn?
