Hello,

If i've well understood the PWM fan is the only one that can be controlled by the GT2560 board.

So i'd like to know how to set the firmware in order to switch it on/off using pronterface's command interface and indeed the slicer ( i use cura).

Thank you for any advice.

Haven't used the prronterface before, but I think you can add a start gcode such as "M106 S200" to turn it on, and M107 to turn it off, check the G-code of the reprap link here:

Thank you very much!
