3D Printer over USB

finally I had time to rewrite my software for the stepper motor controller card, so now I can use it over my USB IO board/expansion board. Now all that is left to do, is the additional stepper controller (my circuit), but I guess I forgot to buy some parts for it, so it will take a while... and then yeah, build the damn mechanics!

Expansion Board IO

Here a demo of using my Expansion Board for IO

Expansion Board

yay, finished my expansion shield for my IO board, so now I have access to data0-7 and strobe on parallelport! this way I can do usually LPT bitbanging or in my case control a stepper motor card!

And done! added the other 12 pinouts, some hotglue to the usb port and made some "feet" out of the hotglue... works 1A!

USB 4 All

finally all parts arrived, and I could solder the first time this year :D this is my all-in-one-IO circuit, after sprut's USB4All circuit and firmware (source) also wrote a little testprogram to flip a LED on/off
