Ligthburn doesnt work good, wierd problems

[b_art (Bartłomiej)]

Hello
I build my own CO2 laser 50W ( only for start).
Quickly to the problem, in LaserGRBL everything is working correctly.
Directions all good, laser power all good, cutting engraving all good!

But only when i switch to LightBurn directions Y and X going wrong (opposite),
Laser power even on 100% seems like around 10%.
Also when I try to run some longer cutting and engraving ( this interval test) LightBurn is crashing!

I’m using GRBL 1.1g with Arduino UNO ( original one, not clone) Step drivers DM556
I have homing on the right top so I set OFFSET by
G10 L2 P1 XX YY my work area is 855x 805y
All work perfectly in LaserGRBL.
But I bought a license for LightBurn for GRBL and I want to use it .

My GRBL setting in attachment

It seems like everything with my machine is OK!
But Litghburn software doesn’t work correctly.

Hopefully, together we might figure it out

Can you take a screenshot of Edit->Device Settings in LightBurn?

[b_art (Bartłomiej)]

Can’t do it now. I have the laser in another place.
But I’m sure they are exactly the same, I have checked that.

@b_art

But I’m sure they are exactly the same

Same as what? Note that I’m not asking about GRBL configuration.

Sorry, I thought you asking for GRBL
Okay, then I will send a photo in a day or two.

Looking for help

Your jogging control issues are caused by a misconfigured Origin value in Edit->Device Settings. Set yours to bottom-left dot.

I don’t see any reason why your power would be reduced, however.

How are you comparing results?

It does work properly
I did some simple cutting and engraving tests and all good
Thank you for your help.
