JL1 (JL3) GRBL firmware avialable

@berainlb makes an interesting point here

The photo in post 6 shows the controller and the cpu was tagged as an APM32, which does exist and if @berainlb is correct, it is likely some type of commercial atm32 clone or something. Sounds like the binary will run on either… ?

Do you have a header file or something with the changes to the pins in it? Which pin is the jl1 using for pwm control ?

Any road maps of the board you have would be good, even it it’s this pin does this…

Cloned the github project… Do you have any details on what you have changed so far?

I have another controller on the way from China… It would be nice to use the existing hardware…

My st-link programmer is supposed to be here today…
