G-Code Motion target exceeds machine travel But Does not

LightBurn Software Questions

Running Windows 10 from a Microsoft Surface Pro using freshly downloaded LightBurn 1.7.06 software in a trial. Drawings imported as DXF.

We just purchased a Ortur LaserMaster 3 with an extension kit giving it a 15.5 x 31" cutting area. I cut a couple of tests yesterday and decided to move on to a real file. We drew a rectangle inside the bounds of our machine and had the file “burn” that border first before cutting the parts in the file to be sure all of our parts were inside the boundary of the machine. I also ran the “Frame” feature for the same reason. Each time I run the file, the perimeter rectangle runs fine, but then the machine stops in the same place only about 1/4 of the way through the file (See TestGore.lbrn2 attached).

After trying to run the file 4 times, I decided to try to only run the middle pieces shown in the drawing (see Test Gores2 attached). That file stops after only cutting the perimeter and 2 lines in the drawing.

After searching the internet, I installed the latest firmware from Ortur but that did not help at all with exact same result.

Maybe a clue…As mentioned, the Laser cuts the 15" x 30 " perimeter, but on the 2nd file, it seems to stop very near the center of the Y direction on the machine, possibly as though it thinks the machine only has a 15x15 limit though obviously it does not by virtue of cutting the perimeter rectangle.

Each Time I run the file, LightBurn gives me some sort of error and the machine just stops with no way to start it back up again other than starting over.

Any ideas would be greatly appreciated.

I can’t run your file (but I did look at it), but is it possible the Kerf Offset is just enough to get you out of bounds?

Mike,

Thank you, I like your way of thinking but, no, my kerf compensation is set to 0.01 and the parts are about .25 from the bounding box.

Did you make the size changes in the firmware? Type $$ in the console an press enter. Copy & paste the output here. Also, post a screenshot of the Settings Window (Gears icon) with the Units and Grids tab visible and post a screenshot of the Device Settings Window (Wrench and Screwdriver icon).

Tim et al,

Problem solved! Your suggestion ended up being the problem, I had not changed the setting in the Machine. It does seem odd that the machine would travel to cut the perimeter beyond its bounds but not the other parts. We had previously looked at the machine settings and could not find the X and Y size to change it. For those looking, there is a small arrow on the left of the Machine Settings to “Expand” the “Outputs Setup” and other settings and that is where you can set the size of your machine.

Thanks to all,

Hal
