Makerbot (Thing-o-matic)


I want a Makerbot Cupcake or a RepRap. Now that I have a CNC mill, I think it would be easier to just add a plastic extruder to it.

Andrew Plumb suggested (a couple of months ago) that I get one of these.

I also need to work out the software chain for this stuff. Any feedback there? My mill is on Mach III at the moment. I intend to convert it to EMC2. Are there any projects that use this stuff?

Jan 21, 2011 update: I have purchased the extruder that Andrew suggested. I also got some 3mm filament to to with it.

Controller: I guess I need to get some sort of controller for this stepper so that I can connect it to a parallel pin on the controller computer.

Heater: What to get for the heater in the extruder? Does that get controlled by a controller or is there a manual setting on a typical cupcake machine? Do I need to know the temperature? Do I need something to display that?

Software: I’ve been using Sketchup and a few other tools to run the CNC mill. How to control the extruder? Is this the A axis? What does this mean when generating the g-code? What is the required chain of programs to get this done?
