by default FAN1_PIN is using P2_04 nd default chamber fan is going to use this fan
but you have set #define HEATER_CHAMBER_PIN P2_04 /// pin for the chamber heater]]> Dust General Mon, 18 Nov 2024 08:47:29 -0500 https://reprap.org/forum/read.php?1,896134,896134#msg-896134 Where did I fail to set up heated chamber om SKR 1.3 ? https://reprap.org/forum/read.php?1,896134,896134#msg-896134
I have this in configuration.adv:

The chamber temperature sensor works - the LCD allows me to set a target chamber temperature.
but the fan never starts.

There is no voltage on HE1 output marked 2.4 : [github.com]
The fuses are ok.

I have never used HE1 before, so there is no reason to believe that the FET is defective.
