Error stopping machine during Lightburn Material test

LightBurn Software Questions

Hello. I’ve been working with my new 10W Diode machine for a few weeks now, and this is the first software issue I’ve had. I have run material tests, cut tests, engraved, cut out shapes with no problem until today (12/22/2024). Today, I successfully ran a material test, but when I tried to run a 2nd one, and I ran the Frame function, the gantry moved towards the working area, but then stopped and I observed the following error code: E (26) efuse: Range of data does not match the coding scheme
I’ve power cycled the machine and restarted my windows PC several times, but the error is persistent. I can run a prior engraving file, no issue, but the Lightburn Material test function fails with the same error message. It fails whether I run the Frame function, or run the Material test.
The error recurs with my Acer notebook running Windows 10 and my HP Notebook running Windows 11.
Machine: Lasertree LT-K1 MINI, 10W Diode
Controller: GRBL, but not sure how to obtain the firmware version. I found this article, but I don’t see the firmware version? Machine Settings - LightBurn Documentation
Lightburn version: 1.7.04, recently upgraded from 1.7.03. Paid license.
I even uninstalled 1.7.04 and reinstalled 1.7.03, but the error persists.
Thanks for any advice.

Not sure if this is a GRBL Error 26 or not. Assuming it is, it is saying a GCode command was issued with no X, Y, or Z info. That is pretty strange

This implies there is something wrong in the code generated for the Material Test. A Windows update might have messes with one of the Lightburn files.

Download a fresh copy of the Lightburn installer file. Reboot the machine, and reinstall Lightburn.

If that does not work, do a Save GCode to a .NC file in the Material Test using the same settings you have when it fails. Upload that file here so others might inspect it.

Thank you Mike! Much appreciated.

What I did:

  1. Removed Lightburn
  2. Downloaded fresh copy of Lightburn
  3. Restarted PC
  4. Installed Lightburn (1.7.04)
  5. loaded prior engraving file to confirm it still worked, but when clicked frame, it failed. Attaching file “2024-12-23_01 kickit prior file fail code.gc”
  6. Opened Material Test, default engraving test for diode laser, clicked frame, failed. Attaching file “2024-12-23_02 kickit matl test fail.gc”

If this is going to be hard, I’m still within the Amazon holiday return window.

Update: Oh, when I say ‘failed’, the gantry moves about 3 to 4 inches, then freezes.

Thanks again and Happy Holidays.

If we cannot figure out what that error message is really telling us, it can be.

You uploaded 2 failed GCode files. I was hoping for one bad and one good so we can compare the GCode instructions. I reviewed one of the files and say nothing wonky.

Try this…
1 Enter $# in the console window. Look at the G54 line. It should be all zeroes.
2. if it is not, enter $RST=# in the Console window and retest. This will erase the G54-G59 and G20/G30 workspace offsets.
3. If it is all zeroes, Amazon is your best friend.

I can make a suggestion on a replacement, but I so not know your needs and budget.
