CNC Magic Screen Machine

Description:

This is the update for the Magic Screen Machine

I have added the ability to control the machine via the open source EMC2 machine controller software system.

Warning: This is an advanced project that is likely to destroy things. I lost a atmega8, uln2803, and a stepper motor in the process of building it. No, really! Since it hooks up via a Parallel port to a computer, who know what damage it could do.

Schematic:

Schematic in ExpressSCH format

Source:

Source for ATMega8 running at 1mhz using internal oscillator.

Notes:

Prototype Version.

Finished Version.

To see how the frame to attach the stepper motors to the device was made see blog entry covering the building.

Inspired by etch-cnc

None of this would be possible without the tireless help of Paul Atkinson (Electronics Genius Extraordinare).

Thanks to Bob Sheldon for doing the finishing work on the final design.
