Help needed to remap fan1
I had a wire break on my hot end fan and the wires shorted and fan1 port is no longer working. Can I use fan2 for the hot end and how?
Duet2 maestro and firmware v3
In advance thank you

There should be a line in your config.g looking something like:
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
you can change "fan1" to "fan2" and it will use that connector instead.
@bondus thank you I will try that.
@bondus That did not work, did i miss somthing?
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan2" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
M563 P0 D0 H1 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0
That did not work, did i miss somthing?
Did you also move the fan port for the hotend fan to Fan2 port?
Yes i did, mabye it is blow to
Have you checked the fan fuse?
Does the fan work when connected to the always on fan port?
@Phaedrux yes it does, that what i've done to keep the printer running. where would i find the fan fuse?
sorry for alle the questions.
Sorry, I see now that you're using a Duet Maestro, so no replaceable fan fuse.
Since this is the hotend fan, you could still use the always on fan port. If fan port 1 and 2 are no longer working.
Actually. the fan 2 block has it's own voltage select jumper, how is it set? Perhaps it's not set properly and that's why your Fan2 port isn't working as expected.
