[BUG] SKR MINI e3 v3 Controller Fan always on
Description
I have 3 machines with the SKR mini E3 v3.0 and the exact same firmware. After powering on the machines the controller fan of two of the machines stay silent unless a strepper gets activated. On one machine, the controller fan runs permanently and doesn't respond to any command.
Firmware is the actual Marlin 2.0.9.3 bugfix branch from the 31st January 2022
Steps to reproduce
- Switch on the printer
- Check if the controller fan runs 2.1 try to control the speed in the menu (if configured)
Expected behavior Should not run/spin like the other two machines
Actual behavior Runs permanently unlike the other two machines
Additional Information
Probably a damaged mosfet that spins a fan. A frequent defect ....

Same issue here, I can't control FAN_1 and FAN_2 using the gcode from Marlin. How can I address the configuration to have them set as P1 and P2? @radek8
@mfaccin What board do you use? Which fans do you want to control on connectors FAN1 and FAN2? What do you mean P1 and P2? Submit your configuration.
@radek8 I'm using the SKR E3 mini V3.0
I intend to use two 5010 in FAN1 and FAN2 and an axial fan in FAN0.
According to the https://marlinfw.org/docs/gcode/M106.html I can select the speed of the FAN0 using M106 P0 S_, but it doesn't work with the other two.
Do you use all 3 fans to cool the printed part? I'm not asking about the fan model, but about what part of the printer it's supposed to cool.
@mfaccin Send me your configuration files (Configuration.h and Configuration_adv.h) from which you compiled fw.
@mfaccin If you want to control multiple fans with command M106 with index P0 to P2, you must define the number of fans. #define NUM_M106_FANS 3
My SKR mini e3 v3 Fan 0 is always on. It has a bad Mosfet. How do I get it fixed or replaced??? This is my seccond board. The first one had issues as well. The 5v Regulator is bad on it and not able to use. What is the deal with Bigtreetech and there quality control. I don't think I will buy another one of there products!!!
