Hello :)
After soldering a bit, I managed to plug a Panelolu 2 screen on a RAMPS 1.4. It works nicely but I'd like to add a (controled) fan. Apparently, the transistor 1 of the adaptator allows this since it is linked to the pin 45 which is controlled by PWM.
I tried to activate this pin 45 in Marlin by changing the pins.h (maybe wrongly) but my fan still don't work.
Also the 12v output of the adapter is not working.
Is there something special to do ?
Sorry for these noob questions :)
Thanks,
Arnaud.
