I used the absolute coordinate system as a reference in the Lightburn (see screenshot).You can naturally choose your own starting point, different to this one.

The left bottom corner of this square is positioned at x 200mm and y 200mm coordinates (see screenshot). made a file in Lightburn (that is the SW I use for laser projects) with simple square frame of a size 300mm x 300mm (you can make different size).zeroed the Z at such height to be able to laser directly on my wasteboard.after having installed the Onefinity 1.0.9 firmware upgrade it is possible to home the machine and laser afterwards (I had problems with that before).It really bothered me especially during the testing of speeds and power on different materials, so I decided to use absolute coordinates instead of user origin. Maybe somebody already posted similar thing, anyway… If I may, one tip from my experience to AVOID REPEATED FIRING OF LASER WITH MDI and setting xy starting position. I have used/saved multiple toolpaths at different powers and run as one file, just like you can do with multiple tools.

I noticed that i start getting marks in the 20% power mark(equivalent of M3 S200, well above the S20 mentioned above), but it is very very faint in Pine. In Vectric, I have my default tool set as 80% power and when I build the individual toolpaths I set the specific percentage of power based on my needs. Once that is done, turn off the laser and then use the included 1/8' spacer to set the Z zero to get it to the focus point. When done maneuvering it to the XY zero, use M5 and hit play to turn it off. You can either use this method to set the XY zero on either a corner or center of the workpiece. Use controller or joystick to move to XY Zero. This should not burn anything at this power (Make sure you are wearing your laser protected eyewear) Once you find this number, it should be consistent for your laser. To test fire you can use the MDI section and manually type M3 S25 and press play to fire at 2.5% power, increase the S setting by +5 until it fires, if it does not light up initially. I have my laser about 2-3' above the workpiece, in general area of XY zero This is the way I do it, not necessarily the only or best way, but a way.
