with a direct USB connection my little CNC does a fine job everything works well.
During the lasering I usually place the CNC outdoor. As not to use the PC I bought a little offline controller.
I can control the CNC and also printing the example files of the controller works fine, but printing the Lightburn file does not work.
If I start the GRBL file from Lightburn the controller shows immedeately “printed” but nothing happens.
I think there is an issue with the header of the files:
G0 X21.0087 Y10.646
G1 X20.3867 Y10.646
G02 X19.6926 Y10.7646 I-0. J2.0906
G02 X19.3633 Y11.0062 I0.2335 J0.6636
G02 X19.1824 Y11.3961 I0.8284 J0.6211
G02 X19.0932 Y12.1849 I3.4437 J0.7888
; LightBurn 0.9.11
; GRBL device profile, current position
G00 G17 G40 G21 G54
; Cut @ 400 mm/min, 100% power
I bought this controller:
Has anybody an idea?
Thanks for your help in advance.
