I think I partially cracked it after going a bit crazy on it myself.
(Updated to Luban 4 today)
Essentially I see troubles with the workflow, which could be improved.
I started with creating my Laser project (added picture, text, etc…).
Then I took an camera capture to see the board and properly sizing whatever I put.
From this point onwards the Work Origin is locked.
Forget about the correctness of the values, adjust based on positioning, that it looks centered or where ever is has to be.
Remove the Camera Capture and then change the Work Origin to Centered.
Create your G-Code, load and run a boundary to see if you need to Offset, for me it’s about 10,10 where I am usually off.
If someone would have an easy solution to be able to center pieces, I am very open to ideas.
The dot thingies are unpractical and difficult to use, so for now I tape the boards as best possible.
Maybe this could be fixed along a boundary run ? Checking it the laser hits the board or not anymore ?
If that could give feedback to reanalyze the gcode and adapt to it automatically ? (aiming at propper rectangular/square shapes)
MAJOR Issue : The Lasering can’t be stopped !! No Pause or STOP button work on the Touchscreen.
Only Turning off the PSU works.
Hope this helps a few of you.
