Small mosfets always on

I purchased a smoothieboard for my Delta build, and have just about everything running nicely, except for my fans…I am not able to control the P2.6 or P2.4 mosfets, they just stay on. P1.22 works just fine.

Additionally, P2.6 (the one which is set as default fan control in the config) seems to be under powered, while 2.6 and 1.22 are at 12v, 2.4 is at 3.3v.

Any idea what could be happening?

Hey.

Mosfets always ON are probably a problem with the board.

I recommend you contact whomever sold it to you ( which could be me :slight_smile: ) so they can help you figure out what’s up.

Cheers.
