Configuration of a MCU controlled fan
-
Hi there,
I have problems configuring a MCU temperature dependent fan.
Hardware: One MB3HC6, Two HC3 and a Raspi 4BThis is how the fan is configured:
; System Temperature Sensors M308 S10 Y"mcu-temp" A"MCU" ; defines sensor 10 as MCU temperature sensor ; Electronic Cooling M950 F8 C"2.out3" Q65535 ; create fan 8 on pin 2.out3 on MB3HC Board #2 and set its frequency M106 P8 C"MCU-Fan" T20 H10 ; Test MCU TEMP and FANThe MCU shows a temperature of 40-45°C, but the fan doesn't move.
If I set the fan manually:
M106 P8 C"MCU-Fan" H-1 ; set fan 8 value. Thermostatic control is turned OFFthen I can control it normally.
can it be that the fan must also be connected to the HC6 board, i.e. the board where the temperature is measured?
Second question:
I noticed something else, when I use the rrf config tool, all fans, with a connected sensor, get an H5:XX; Fans for Tool's ; Tool 0 -------------------- ; PartFan for Tool 0 M950 F0 C"out4" Q500 ; create fan 0 on pin out4 and set its frequency M106 P0 C"T0-PF" L0.35 S0 H-1 ; set fan 0 value. Thermostatic control is turned off L0.35 = MinimumSpeed 35% ; HotEnd Fan for Tool 0 M950 F1 C"out5" Q500 ; create fan 1 on pin out5 and set its frequency M106 P1 S1 H5:1 T45 ; set fan 1 value. Thermostatic control is turned on ; Tool 1 -------------------- ; PartFan for Tool 1 M950 F2 C"out6" Q500 ; create fan 2 on pin out6 and set its frequency M106 P2 C"T1-PF" L0.35 S0 H-1 ; set fan 0 value. Thermostatic control is turned off L0.35 = MinimumSpeed 35% ; HotEnd Fan for Tool 1 M950 F3 C"out7" Q500 ; create fan 3 on pin out7 and set its frequency M106 P3 S1 H5:2 T45 ; set fan 3 value. Thermostatic control is turned on ; Tool 2 -------------------- ; PartFan for Tool 2 M950 F4 C"out8" Q500 ; create fan 4 on pin out8 and set its frequency M106 P4 C"T2-PF" L0.35 S0 H-1 ; set fan 0 value. Thermostatic control is turned off L0.35 = MinimumSpeed 35% ; HotEnd Fan for Tool 2 M950 F5 C"out9" Q500 ; create fan 5 on pin out9 and set its frequency M106 P5 S1 H5:3 T45 ; set fan 5 value. Thermostatic control is turned on ; Tool 3 -------------------- ; PartFan for Tool 3 M950 F6 C"1.out3" Q500 ; create fan 6 on pin 1.out3 and set its frequency M106 P6 C"T3-PF" L0.35 S0 H-1 ; set fan 0 value. Thermostatic control is turned off L0.35 = MinimumSpeed 35% ; HotEnd Fan for Tool 3 M950 F7 C"1.out4" Q500 ; create fan 7 on pin 1.out4 and set its frequency M106 P7 S1 H5:4 T45 ; set fan 7 value. Thermostatic control is turned on ;--------------------------------------------------------------------------------The XX is then the right fan, but what does the 5 mean? Because the 5 then stands in front of the actual fan number for all fans. Everything works perfectly (with and without 5), but the 5 doesn't belong there, does it?

Can you share your full config.g and the results of m122 and M98 P"config.g" please?

@crazycreator please check that the 3HC board is also running firmware 3.4, because this combination (fan connected to an expansion board and temperature sensor connected to a different board) was a known limitation of firmware 3.3.

@dc42 thank you ...

@crazycreator I believe this is fixed in RRF 3.4.2rc2 which has been released today.

Thanks for the tip...
I've already installed the update, but haven't gotten around to testing it again yet.
