Hi.I have two new extruder boards. My friend has assembled them, and on the BOM it says that it should be a Mega 328p so he fitted those. The PCB's are the official layout. I replaced the Mega 328 from one of the boards to be an Mega 168 and flashed bootloader, and ReplicatorG flashed the firmware on it perfectly, and it works perfectly.
Now, i want to be able to re-compile the firmware from sources so i can run it on the Mega 328 too, but before doing that, i wanted to make sure that my compiler environment is working 100 % as it should.
I am running Mac OS X (Snow Leopard)
I looked at http://wiki.makerbot.com/v2-firmware and followed the instructions 100 % regarding the usage on Mac OS X.
I need to compile firmware for the Extruder Controller, and i see that the sources i got from Git is v2.9 - i found out how to get the same software as ReplicatorG ships with (v2.8) so i am working with the same source.
Running this command "scons -f SConstruct.extruder" generates this output:

All looks OK!
Then i flash with: "scons -f SConstruct.extruder port=/dev/NAME_OF_YOUR_SERIAL_DEVICE upload"
avrdude: error reading system wide configuration file "/usr/local/etc/avrdude.conf"
OK, i can handle that, i copy the avrdude.conf from "/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/etc/" to "/usr/local/etc/"
I had to make the etc library by doing a "sudo mkdir etc" because it didn´t even existed.
Then running "scons -f SConstruct.extruder port=/dev/NAME_OF_YOUR_SERIAL_DEVICE upload" gives me this:

It flashes perfectly, but the Extruder controller does not work at all!
Flashing the EC from within ReplicatorG works perfectly, flashing from terminal results in a dead EC and i get the dreaded Toolhead 0: Not found upon connection from ReplicatorG.
Can someone point me in the right direction, what am I doing wrong ?
Regards, Per.
