*Updated Pen Plotter Attachment
Description
*Just updated it with an extra piece that you can print and strap on with rubber bands that allows the pen/tool to travel slightly, allowing better contact with the surface. It does this while still allowing the pen to be picked up off of the surface when you need to start a new line.
Instructions
*for the extra addition print out two vsidetop's and clamp together around the top of the pen with 2 m3x30mm's. reduce the tension in the main body to allow the pen to slide up and down and attach the top with rubber bands.
I have yet to really mess around with the g-code * it to draw cool things (will definitely have to try TMR's parametric stuff sometime) but from my work with the frostruder editing the G-code shouldn't be too daunting.

Wow I'd like to have a pen on my makerbot... I'm printing one right now :)
I'm having no joy converting those STL's with skeinforge for my cupcake, any hints you can share?
hmm weird. Have you got other things to slice with skeinforge? My models are usually non-problematic because I use a solid modeler (as opposed to something like Blender that uses meshes) and I know for a fact that at least two others have got it to work. I just tested it again and it's working on my machine. What exactly is skeinforge saying when you try to slice it? Also what version of skeinforge are you using... we've found the must robust version is 005.
Neat. My only criticism is that it'd be nice if there was a way to allow the sharpie to ride up and down a bit so there's merely pressure applied, not crammination of the tip..
Awhile back I was testing a homebrew cnc router, and made a little sharpie spindle which used a rubber band to keep a constant pressure, and a strip of duct tape wound around the sharpie as a shaft collar between two bits of MDF- http://www.flickr.com/photos/v... maybe something similar would work here?
thanks for the great suggestion. I uploaded my solution and although i haven't tested it on the makerbot itself it seems to work really well.
wow nice. yeah I was thinking about something similar. I'm thinking you could use the existing parts but add a top piece that would be strapped down with a rubber band like yours. I'll try to get something uploaded tonight.
Made myself one of these , The stage mount gets a bit blobby without cooling but it works.
I'm going to have investigate drawing PCB boards.....

Uh.... where on the makerbot are there m3x30mm screws?
Got it to hold with rubber bands. Know any software that can make gcode for it?
I think they used to be on the MK3 extruders but they're probably not being used anymore.
