Thanks, that’s perfect!

Hey guys.

I've got a problem with my fans. Everything works except for fans 0 and 1, leading me to believe it could be a problem with the mosfet drivers.

Anyone have troubleshooting ideas or know what kind of mosfets they are and where they are located on the board to be replaced?

Thanks a ton!

Thanks for the help. So does that mean that the bridging fan speed override affects all fans and the fan speed also affects all fans? If so, when I set my Hotend fan to thermostatic control, will the S3D fan settings not affect that?

Wow, thanks. I have a question though... Where would I put those in in the Duet Configuration and would things like bridging fan speed override still work for the nozzles?

I have the duet 2 ethernet and would like to use the 3 Pwm fan outputs for different things. I would like to have fan 0 be a thermostatic controlled fan for my Hotend so that it turns on when its over a certain temperature. The problem comes with the part cooling fans. I would like to have two of them, one for each nozzle. I don't know how to set this up properly as simplify 3d doesn't seem to give many options for cooling fans.

I have found the below lines of gcode that might relate to the topic, but Im unsure what to do with them and how to control them.

{TOOL0REPLACE "M106 S0" "M106 S0 T0"} ; tool 0 uses fan 0
{TOOL1REPLACE "M106 S0" "M106 S0 T2"} ; tool 1 uses fan 2

I was thinking that it might be possible to simply put something in the layer change script that sets each fan through gcode on every layer change to accommodate a lower speed on lower layers, but I would also like the bridging fan speed override to work with both nozzles.

Anything anybody knows on this would be invaluable to me!

Thanks, Ethan

Is it possible to connect a ramps basic display to the duet board via the CONN_LCD output connector? I want to see if anybody else has had this work before I attempt it just in case it hurts my board.

Thanks for the help, Ethan

Thank you, that worked!

I have also tried these, however none of them have any effect on my connected fan

@eth7an If it helps, I'm using a DUET 2 Ethernet on the latest firmware version. I have the fan connected to the Fan header 2 as well, even though I have tried all of them.

I have been reading up on the GCode necessary to convert one of my Pwm fan headers into a dimmable LED control. To do this I have disabled the fan using M106 P2 I-1 and then tried to use the M42 Command to activate that pin. I still have the header connected to a fan while I try to get it working, but the command does nothing to the fan and returns an error:

If anybody knows what Ive done wrong, that would be a ton of help!

Thanks for the help, Ethan
