Parts fan always on

[ortondale]

Sorry to bother you kind folks again
On testing my new install with Duet3 Mini5+ and toolboard 1LC v1.3, I find the parts cooling fan run continuously from power up. The hot end fan is ok coming on at temp 45c.

Connected fan to OUT5 on main board and it worked ok, coming on at second layer.

Have I got the wrong pins connected on the toolbord?
Should it be +VOUT and out1 pins not GND and +VOUT

Toolboard

Config.g
; Fans
M950 F0 C"121.out1" Q500
M106 P0 S0 H-1
M950 F1 C"121.out2" Q500
M106 P1 S1 H1 T45

Also in Web Controller both fans show up, but when I adjust /move one slider the other slider moves the same.
Any advice would be appreciated.

There are two sliders. One is for the currently selected tools fan and one for the fan itself. Sometimes they are the same, like if you only have one tool.

Yes. You have it wired as an always on fan right now.

@ortondale Hi Phaedrux

I don’t want it to run all the time
I require it to run say on second or third layer. Should the black negative be on pin out1 for this to happen or on out1.tach.

You had it right here. Out1 is the PWM switched ground.
