I have read is a couple of posts on the web that this company’s wiring has been reversed.
The posts state that the PWM and GND wires are reversed.
I hesitate to swap them as I don’t know what it would do to the Woodpecker board or laser.
ok moi aussi j’ai un problème avec le traçage installer sur windows 10 et imac et ca fonctionnait tres bien mais la les 2 ordi font le meme bug et avec le programe GRBL tout fonctionne bien assez bizzar non…que faire…
I have a K40, that came with the M2 Nano board. I replaced it with the MiniGrbl.
After the installation of the MiniGrbl was complete, I decided to tinker a little bit with the wiring. I installed a 3 way switch, so I can have the laser activated by the Grbl using the PWM wire (for cutting jobs), or have it fired using the original K40 wiring (to be able to use the TEST button, for mirror alingment, for example).
However, if I send a design from LightBurn when the switch is set to the original wiring, the laser will be always on, even on blank spaces.
Hope this contributes to shed a light on the problem.
