I have two almost identical 3018 (grbl 1.1) CNC routers
one for Laser with Lightburn Software and
one for Milling with bCNC Software.
Lightburn works well, but still I would like to see more real time information about the M and the W position of the laser.
Where “M” is the position relative to the Machine “HOME” position and “W” is the position relative to the “User Origin” position. The later falls to 0,0,Z after pressing “Set Origin” (or XY=0) or it falls to 0,0,0 after pressing XYZ=0.
Would be nice to have this information in the ‘Move’ window.

LightBurn does not use the workspace position as you think it does - when you set a user origin, no coordinate system info is changed, it just remembers where you want the job to start. What’s the reason you want to see this info?
It happens to me to often that I am taken by surprise by this Software. The laser starts at a very different point than where I expected it would start.
Again . . . when I compare Lightburn with bCNC.
In BCNC you can always see in XY-view or in ISO-view animation, as well as in Work and in Machine coordinates where your spindle (or laser) is which leads to less mistakes (or surprises).
In LightBurn, your machine coordinates are all you get. There are not “work coordinates” in the same way as there are with a CNC machine, but you do have a user origin, and you can press a button to move the machine to that location at any time.
When using LightBurn, if you are moving the workspace origin to be anywhere other than the machine origin, that is likely contributing to your troubles, because it simply does not work that way. LightBurn was written for dedicated DSP laser systems first, and then GCode support was added, so the way things work is much more like dedicated DSP software than CNC software, and that is by design. If you are trying to use it the same way you use CNC software, you will be fighting the way LightBurn wants to work.
