I did the software update without installing the COM driver.
Start LightBurn:
Waiting for connection…
OK
[VER:1.1f.20180715: ����������������������������������������� ���������������������]
[OPT:VMZ,35,254]
Target buffer size found
OK
Test cut / print was OK!
I used these settings…
GRBL_M3.lbset (5.4 KB)
sorry cannot upload any *.lbdev…
GRBL_M3.lbdev.txt (2.8 KB)
remove “.txt”
The name of the file threw me off. I get that it has M3 based on the “Mr Carve M3” but there’s a device type called GRBL-M3 that’s meant for legacy GRBL devices so did a double take. For the record it’s indeed standard GRBL, not GRBL-M3 device type defined in the file.
“Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, lbrn, txt, lbset, lbrn2, csv, svg, dxf, markcfg7, markcfg0, lbcm).”
NO .lbdev
Add .txt as an extension and you’ll overcome this. Drawback is that people will need to rename.
