Hi

My 2 heads printer is driving by a rumba card.

How i can manage a fan on pin 8 for cooling my card with the pin chamber sensor 12 (exp: if temp > 50 then fan one speed 255)

I don't find this possibility in repetier.

Actualy I use manualy or in GCode M42 P8 S255

Thanks before

Simplest solution currently would be either

#define FAN_BOARD_PIN  pinnumber

#define SHARED_COOLER_BOARD_EXT 1

With 0.92.3 it will enable fan if heaters go on or are hotter then EXTRUDER_FAN_COOL_TEMP

Thank for your reply.

I'll test this solution.

I just found that with the #define FAN_BOARD_PIN of 0.92.3, the fan is on when the bed is heating, but also when stepper motors are active. This near what I want for protect my card, even if the ventilation is not related to the temperature.

Thank you for the good job done by the Repetier team.
