Xtool D1 Pro GCODE wrong

LightBurn Software Questions
1

Hello together,
I have a problem with my new xTool D1 pro, burning a grid.
The grid in LightBurn looks good - but when I burn it, there is a crash moving the x-axis to -16 (minus 16). This is also shown in a gcode viewer (ncviewer.com)
LightBurn view:

image667×905 80.6 KB

But when I create a gcode file, than it shows some movements to the minus X axis!

move1
move11296×1069 302 KB

later in the gcode file - there are moves to x-16
move2
move2894×993 177 KB

and this is the first X-axis crash.

This are the first lines of the GCODE:
; LightBurn 1.2.01
; GRBL device profile, absolute coords
; Bounds: X-0 Y0 to X420 Y400

What can I do, that the GCODE is exported as shown in the LightBurn software?
Thanks

That’s odd. Can you upload the .lbrn file for review?

Hello,
because of copy rights, I reduced the content, but the failure still exists!
GridLBurn.lbrn2 (153.6 KB)
and this is the GCODE:
GridLBurn.gc.txt (113.6 KB)

I hope some one is able to support.
Thx

I think what’s happening is the negative X coordinates are there due to pointer offset configured for the D1. So in order to accommodate the -16 mm offset configured for the X axis the g-code has to go negative.

@berainlb - Thanks, but where can I change this offset?

This is defined in Edit->Device Settings.

It’s necessary for the functioning of your laser assuming you are using the crosshair pointer. If you do not use the crosshair then you can remove it.

The reason it’s configured is because the crosshair location is -16mm offset from the primary laser. So you frame with the crosshair but then need to shift for the actual laser operation.

@berainlb - Thanks, it works!

But when I use absolute coordinates, than this is not a good feature. Because with absolute coordinates I do not expect to have a pointer setting that is changing the coords.

8

If you don’t want to work this way then just disable the crosshairs and use the primary laser for framing.

Enable the “Enable laser fire button” and “Laser on when framing” in Edit->Device Settings. Then set the power level very low in Move window.

THANKS - but this I have done already in the past. But not changed the offset pointer.
Have a good weekend!
