Machine: K40 with M2 Nano (Replacing)
Board: Replaced with 3D Cohesion board
Firmware: I have a new board and I’m using whatever it came with
Problem/ Question: Installed new 3D Cohesion board and downloaded/installed LightBurn. I can move the head assembly but the LASER will not fire. The light in the cabinet will not come on (it used to), and the power output display does not come on either (not sure if this is something built into the new board). In any event, new board installed per instructions and it will not fire.
