Pic based electronics. by volunteerlabrat Mar 30, 2012

Description

I have designed my own reprap electronics based on a PIC18F2620 micro controller and A3982 stepper drivers.

It has been designed to be as cheap as possible. If you can etch the board yourself it should cost no more than 40 euro (55 usd) to build.

It all fits onto a 160x100 eurocard sized PCB and is currently running on two repraps.

I am happy to share the firmware source and the PCB layout. As for now however I'd like to run more tests with it before I release it.

Why not share it now? Take just a week before posting this. I was forced to solder some capacitors to the rear side of the PCB to remove EMF. I have yet to add those to the schematic.

Hi, id love to get the pic firmware and basic schematic, not important to have all the documentation as i can decipher it myself :) was going to do this myself, but why reinvent the wheel? :)

Hi there!

Don't miss out on the "Race to the Bottom"-electronics competition over at the RepRap-wiki: http://reprap.org/wiki/Race_to...

Have a great day! :)

I've been working on it just yesterday.

Hunting EMF noise. Increased the size of most pads so that people without insane soldering skills has a chance to solder the board.

I have also begun to document the firmware source. The latter is quite a boring task but I guess it has to be done before I release anything. *DONT_KNOW*

All the b
est!

this looks great! can't wait to see the final design!
