Was sent a copy of the docs, since the URL doesn't work:
http://atomsofttech.com/downloads/AtomCNC.pdf
Received permission to upload it to the wiki, so it's linked on the AtomCNC page --- anyone who has any useful tips / information, please post it there.
After reading through it, my understanding is:
- the board can be powered by USB for purposes of the computer interfacing w/ it / it running, but not moving the motors
- there's a separate power lead to connect the 24v 5a power supply to which will provide power to the motors
- there's a pass-through connection for 110v AC which the board is able to switch on and off so as to power / control the spindle
Still not getting where to plug in a fan, but will have to re-read them.
