need help to program sanguinolou (4 replies)

Hi I have put together a Prusa Mendel Printer, it has a Sanguinololu board, the kit came from Amozn. All it does when it is powered is to move the x and y motor a few steps in each direction and back again. So the board must have a boot loader! and some sort of a program. I have a new Atmega chip and a Arduino uno. I have arduino 1.01 version and have added gen7 to it. I am using the Arduino with it chip in and using the MSo MSI pins The Arduino has a 1284 board listed and I was able to burn a bootloader and write blink to the new chip. I have tried to compile sprinter It reports an error Cpp:28:/pin.h:439:3 .
It will compile using 2560 mega !
Can Anyone Help ! I do not Know what I need to Do.
Thanks Alan.
