So, I had to do some routing and now trying to set Lightburn back up.
Dreaded doing this, but eventually with help I can at some point move between routing and laser without spending hours of what’s left of my life trying to reconfigure things each time.
The closest I have gotten so far is seemingly everything worked but the framing was off.
This current config. won’t let me move without out of bounds warning.
For the life of me I can’t seem to grasp the coordinate system’ and yes I have read about it numerous times.
My understanding is that CNC is 0,0 in upper right corner and if you put neg. offsets on X,Y that should make things work.
Should lower left then be 0,0?
I am also confused on what and where origin should be. Does it affect 0,0?
I home to upper left.
Any help would be greatly appreciated.
It seems to work and provide the offset as per screenshot. Only my Z axis will move without out of bounds warning. Correction, my Y back button will move laser to the front where it reports 0,0.
Couple questions:
Your origin upper left is correct?
How are your GRBL settings?
Do you have any offset?
Origin was one of my questions. What does it do/effect?

Does your machine work well in CNC mode?
And have limit switches at upper left?
CNC works well and yes limit switches are upper left.
Not sure if what your experiencing is similar to what just happened to me. I switched to using lightburn to control my cnc router and decided it was too much trouble. For some reason I could not set my origin and got error messages that a hard limit switch was tripped. Resetting this offset worked: In the console, enter G10 L2 P1 X0 Y0. This is generally only required if switching between using your machine as a laser (with an offset) and as a CNC machine in software that expects negative coordinates.
My best guess is the Macro didn’t execute the control back to the laser but this reset got everything working.
Good luck and hope this is helpful.

Your limit switches ($21) aren´t enabled in Settings.
Per Y moves you could try change your origin in Lightburn to other origin point ( ie. if set to upper left choose bottom left or reverse )
My understanding is you use this to clear offset so CNC will work, and you need offset for Lightburn. But I have been back and forth with this setting also.
I have never had hard limits enabled.
I will try moving origin around.
Moving origin only got me a change in Y movement.
Seems my get position numbers should be positive and not negative.
With CNC machine option enabled and origin change does Lightburn works ok?
I believe CNC machine is an option for Lightburn to work with machines that have a negative workspace. ( like most CNCs )
I issued G0 X0 Y0 and it went to lower left corner. I issued G0 X10 Y10 and got out of bounds suggesting I am in neg. coordinates, yet these are my offsets
$#
[G54:-1119.000,-638.000,-29.741]
[G55:0.000,0.000,0.000]
[G56:0.000,0.000,0.000]
[G57:0.000,0.000,0.000]
[G58:0.000,0.000,0.000]
[G59:0.000,0.000,0.000]
[G28:0.000,0.000,0.000]
[G30:0.000,0.000,0.000]
[G92:0.000,0.000,0.000]
[TLO:0.000]
[PRB:0.000,0.000,0.000:0]
So, I disabled CNC in device settings, cleared the offset and set manually and things are looking promising.
Next time do the offset only in Y.
Not that complicated. Nothing but adding and subtracting numbers. Look at the big picture below, and reread the explanations again.
