M106 P0 S0 I0 F4 H-1 L0.3 ; Filter fan. Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off, Minimum fan value 0.3, Speed 100%
M106 P1 S0 I0 F4 H-1 L0.3 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned off, Minimum fan value 0.3, Speed 100%
M106 P2 S0 I0 F4 H-1 L0.3 ; Nozzle fan. Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned off, Minimum fan value 0.3, Speed 100%It's likely the F4 that is setting the PWM frequency to 4hz. Default is 500. Test with some different values. Under 10 can be problematic. Each fan is a bit different. Values from 10 to 30000 are valid.

Specifically which number do I change on there? M106 P0 S0 I0 F4 H-1 L0.3. Thank you !

Default is 500.

Ohhh okay... The 4 in the F4 is 4hz. I'll change it to F500 ( 500hz)
I thought F4 was the actual command...
Thank you !
-
I changed the F4 to F500 then to F1000 and still nothing... It's only spins slowly if I have them turn on to 50%. I know they were as they are new fans and again spin but just at a slow speed... Any other thoughts?
Thanks !

Duet 3d Maestro FW: 2.05 (2019-12-13b1)
Update. This printer has duel extrusion capabilities however I removed the original left T0 nozzle. I have the nozzle on the T1 right side port and that fan is the fan that is blowing slow. On the left I removed my original nozzle T0 and that fan is going 100 % blowing a now removed nozzle ( I tried two nozzles and that was a mess so I took the original left one out ) Can you see in the config where I have them mixed up?

I can easly just swap the fan to the other side, but was trying to figure out why this happend and how to fix it. Thank you !

You can change which fan is assigned to which tool in your tools definition. Your config posted above doesn't include your tools definitions (it's in another macro), so I'm not sure what to change.

Question: Is this the latest firmware version for 2.xx
2.05 (2019-12-13b1)
I guess our printers don't like version 3.xx just yet. M3D Promega
Thanks !
