hello, I have a problem with air assist, when I turn on the laser, the air pump runs and cannot be turned off. even if I turn it off in the program during engraving, air assist still works, it does not respond to my commands at all, I have it set to M8 in light burn Thanks for help
Open the cover. There are more LEDs on that board, so it’s hard to judge which one is on. I think there is only one blue LED, but I don’t know for sure.
If you pull IO1 low during a power up it will jump into the bootloader …you can then flash a new version of firmware. This is pretty common on esp32 controllers.
