Video Of A Working PICStep Controller

Again with the late nights, but not because of PICStep. I came home from a late meeting (11pm) and didn't feel ready for bed, so I took some photos and some crappy web-cam footage of the PICStep running via TurboCNC.

You can see my current setting resistors sitting high above the board in their sockets because I haven't trimmed them down to the sockets while I'm still fiddling. You just pop in a new set of 1/4W resistors to set the maximum current of the driver (resistor = 20,000 / max coil current eg. 20000/0.7A = ~27K) and the LMD's take care of the rest!

I've thought of a decent way to do a self-test and also the motor time-out current limit. I'll set to work on the new firmware shortly.
