Minimalism at its best.
The printrboard cost $129, comes with the board, a microUSB plug, and the promises of a smoothly running printer. I have run tests on the X,Y and Z axis, brought the extruder well beyond 220C and have no doubts it will exceed expectation on printing.
Printrboard- wired up and running
(only the middle two pins are necessary for the extruder)
The wiring diagram.
I haven’t bothered testing out the hot bed, because there is little need for one during printing. That leaves 4-6 pins I can use for baking cookies… or whatever. There are pins for a fan which may allow a simple transition to a frostruder. (Generally frostrusion runs on two solenoids. Solenoid 1 thinks it is an Extruder and Solenoid 2 a fan). But more on that later.
That link will walk you through it. ( I would simplify it but it is still under development)
Installing Pronterface and Slic3r is a piece of cake compared to February-March 2012 No need to worry about pyglet, pyserial, pyreadline, etc. It is three clicks and you’re done standard install.
The program is choppy on Replicator 0027 but runs if you use the XML hack found here… http://www.thingiverse.com/thing:12781 and switch to the Baud rate 115200 (klimentkip/teacup) This was tested for frostrusion purposes.
