Its been many years since you posted this, but I'm wondering from you and others, how has this performed with milling PCBs? Thanks and nice design!

Too cool! Love the printed brackets.

What kind of results have you gotten with this attachment? I am just wondering if this would be a viable solution for etching pcb's.

if it is simular to my developmnents, the quality for etching pcb's will be determined to how stiff your build base is. If the build base can twist, as the copper runs through the cutting blade it will push slightly, therefore making 'curved' straight edges. see http://wiki.makerbot.com/roboteernat-s-mill-documentation-pagehttp://wiki.makerbot.com/robot... for a few images - to be updated with further results too)
Cloth bot - id love to see how well urs comes out, being a true makerbot(parts may be stiffer as more accuratly cut)

I added your construction to

I really like your makerbeam-mounts.

Skimbal: Skeinforge can create gcode for milling 3d-objects and visolate can generate very efficient gcode for milling PCBs

What a fascinating and useful addition to the Makerbot tool set. What software do you used to drive the mini cnc? Do you have any examples of things you have made using the system?

I am imagining integrating your design into a combined extruder/cnc toolhead. First it would additively build the object with deposited plastic, and then clean up the details with the subtractive Dremel. It would be a great way to solve the problem of accurately sized holes and parts that need to slot together.

With a dual-toolhead you have serious issues with the extruder touching parts of the object while milling.

Maybe it would be worth pursuing the design of a double-wide Makerbot to allow clearance between the two tools.
