Hello Experts,
hope that somebody can help me.
Based on *.svg files exported from Incscape, I created gcodes with Luban 3.14 in the laser section to cut from 1.6 -1.8 mm plywood.
Meanwhile I wasted a lot of this expensive material.
While the toolpath preview in luban seems to be ok, the representation in ncviewer looks a bit strange , because the model is not in the plane with the workarea.
The cutting results on the A350 however are totally weird. The scale is mixed up, parts of the model seem to be lost and the 3 passes are not congruent but shifted.
Pictures are screenshots from Luban and nc viewer and photos of the lasered plywood
I also made numerous test cuts to calibrate focus length, and found it at 24,3mm.
And yes you are right, it looks like the work piece has moved, but it didn’t.
The pics are showing you, that the preview of toolpath is ok, but obviously Luban mixes up something when generating gcode, or the A350 cannot execute the gcode.
I’m pretty sure, that this did not happen with the luban 3.12, but I will check again.
please find attached the corresponding *.snaplzr file.
The gcode from seem to be ok, every pass starts at the same Point.
But the the linear modules x and especially y look as if they are Jumping some steps…….
This is why I additional checked the work origin of the A350 with a circle that I draw in the middle of the Luban work area.
After homing the A350 moved in this Location as work origin. (s. Photos)
Do you think that is right from your point of view , because it is not the middle of the laser work platform and does not correspond to the coordinates shown on the display.

I am not sure what you want to show with your pictures and i am also not sure if the laser bed behaves like the cnc- or printbed, but they are not useable all over the space.- Just inside the grid.
I would suggest to watch the process and see if there is any mechanical barrier or faulty linear modules or rocking off workpiece.
Are there any sounds which are not normal, like bumps?
Do you use the silikone plugs to secure your workpiece?
I only wanted to say, if you @xchrisd or someone else, you could speak to more people in one post, - no problem…
Next step would be to share your log files.
I would suggest to create a gcode with many fast travels so you could check if the steppers skip steps.

Since I got my A350 I engraved and cutted more than 50 modells. So I know what I am doing.
To check the boundaries is mandatory to position the pattern in the right place on the material. These are basics.
But this check doesn’t tell you, if all passes will be executed congruent.
In my special case pass 1 was right and the 2 following passes were shifted relatively to the 1st pass, although in the gcode all 3 passes started at the same position. If the editor shows me a correct gcode, than the problem must be with the A350
