Do we have to create an always-on fan with M950?
do we need to create an always-on fan with M950 in RRF3? The code in config.g is below.
M950 F4 Q500 ; Fan 4 is an always on fan
M106 P4 S1.0 ; Set fan 4 value, PWM signal inversion and frequency.
With this code I always get an error report: "Fan 4 does not exist". But the fan works normally despite of this error. How can I remove this error report? I don't know, which pin name I have to use for the parameter P in M950.
I look forward to your help. Thanks a lot!
do you mean the always on header on the duet2?
that is always on and can not be configured in the config.
The always on Fan header is not controllable. So its a 12/24V Output
