mini_CNC

AVR code for ATMega32u2 based mini CNC drill press. For a detailed description of this project, see https://acidbourbon.wordpress.com/2015/02/01/semi-automated-drill-press-table-for-pcb-manufacture/

• Prerequisites (name of Ubuntu/Debian packages): avr-libc gcc-avr dfu-programmer

on a debian based Linux machine you can just

sudo apt-get install avr-libc gcc-avr dfu-programmer

• compilation instructions (Linux shell):

get the code (if you downloaded and unpacked the .zip file, you can obviously ignore skip this step)

cd /some/empty/directory/
git clone https://github.com/acidbourbon/mini_CNC

get the LUFA source code, and put it in ./LUFA/LUFA-130303/ finally compile and program the microcontroller code

mkdir LUFA
cd LUFA
wget http://www.github.com/abcminiuser/lufa/archive/LUFA-130303.zip
unzip LUFA-130303.zip
mv lufa-LUFA-130303 LUFA-130303
cd ..
cd mini_CNC/
make
make program

Pull the ATMega32u2 into reset and wait 2-3 seconds before programming. If dfu-programmer is not allowed to access the ATMega32u2 chip, try

sudo make program

You probably should be able to port this software to ATMega32u4, if you change the TARGET parameter in the makefile.
