Hello. I have a 3018 china. I recently bought a new controll card for it Indid by the same as was on it upgraded it to GRBL 1.1h but now it does not matter what power I am setting it seems to use the same power all the time. But when I press fire button and change to different power there is difference. I contacted the seller and he recomend me to use LaserGBRL but same result
I don not know what to do please help
What firmware was on it before? If it was GRBL 0.8 or earlier, the pin connection to the laser might not be compatible with newer releases of GRBL.
It is exactly the same card
And exactly the same pins
