...and here you can see a rather neater encoder lashup.
This pic also shows you the remote 5v power board that provides regulated power for the shaft encoder and limits chips. It also shows you the situation with the PC power supply fans.
I've got a little videoclip of the GM8 operating in pseudostepper mode with a resolution of about 60 steps/revolution (~0.0175mm resolution) with a half second pause between steps. At the other end of the y-axis you can see another little videoclip of the encoder feeding pulse data back to the 16F877A control board.
