I’ve no evidence to blame Lightburn, but I’m running out of ideas as to what is causing my engraving problems. I have a Creality Falcon2 22W. It engraves fine if I use the TF card with a gcode file for printing. It has the latest firmware - 3.05.5.
When I drive it from Lightburn, however, I get a very repeatable error. I get a shift in the X axis (and occasionally the Y axis) of about 20mm. It always occurs in exactly the same place. I am running the latest Lightburn 1.5.05.
The result of the $i command is below in case it is useful.

I am running a laptop with Windows 10 64-bit, and Windows is selecting the standard USB serial driver. I have heard talk that the CH340 driver is required, but I’m not so sure that’s true. I have loaded the CH340 driver, but Windows doesn’t select it.
In the console window I have noticed I’m getting “error:24 Two G-code commands that both require the use of the XYZ axis words were detected in the block.” a few times.
In case it is Electronmagnetic Interference (EMI) I have placed a large clipon ferrite at either end of the USB cable. The USB cable is very stiff so I assume it has aluminium foil shielding anyway. The ferrites make no difference.
Smells like some sort of buffer overflow to me, but I have no idea really.
Anybody have any theories as to why this might be happening? New to laser engraving and so far this has ruined the experience entirely
