Hello everyone,

I just burn out the mosfet on A+/A- (and a power supply) I would like to now how to change the firmware so it use the second mosfet.

So far I found this picture: I guess I have to change pin A1 for D11 somewhere in the program.

I just found a file (pins.h) I ave atmega644 so I will try to change that line:

#define EXTRUDER_1_HEATER_PIN (byte)24


#define EXTRUDER_1_HEATER_PIN (byte)15

Please tell me if you think I'm not doing the right thing.

If you expect an answer it would be really helpful to tell us which type of Electronics you're running and which firmware (version) you've put onto it.

If you have the remix with separate extruder controller board, then you want to go into the Extruder folder and open Extruder.pde with Arduino. Edit configuration.h and near the very bottom, you'll see these:

// MOSFET drivers

#define BED_OUTPUT 15
#define FAN_OUTPUT 11
#define HEATER_OUTPUT 12

If you don't have a fan, then you can swap the Fan and the Heater (11 & 12).

If you have the single board techzone electronics, then I don't know how it's done.
