Hi,
Many years back, I bought a pre-assembled sanguinololu board from geeetech and I'm trying to get it to work now (I wasn't competent enough at the time).
After some research, I have managed to determine there is a bootloader on it, and have a setup that can install the firmware (I can talk to it in G-code now, 644P - 16MHz, Arduino IDE) but I don't know if it's BOARD_SANGUINOLOLU_11 or BOARD_SANGUINOLOLU_12.
When I send something like G0 X0, G0 X1000 (or other axes), nothing happens to the stepper motors. How do I determine if the pololu stepper drivers are still in order? (yes, they are the right way around on the board).
If I want to use the board to drive a CNC, are there any modifications I need to make?
