How do I update RAMBo to enable the second extruder?
I know I have to edit Configuration.h and set
Code: Select all
#define NUM_EXTRUDER 2
Do I need an external programmer for that?

After hours and hours of searching and tinkering I got to this page: http://www.gammon.com.au/forum/?id=11635
Basically it's a sketch that has bootloaders for the ATMEGA chips using an Arduino Uno as the programmer.
You give it commands using the serial monitor.
Once flashed I hooked it up to the RAMBo board using the ICSP header for the ATMEGA2560 and on the Uno also the ICSP header besides the reset pin which was put to pin 10.
And voila I had a functioning bootloader on the RAMBo board!!
Now on with the dual extruders
