Somehow the "required parts" section of this thing seems to be missing.

wait a minute....why does the plotter even need a servo at all?

It's located on the Z-stage.

Is there a centering technique? I am Imagining how the pen attaches and it seems that different size pens/markers will have slightly different centers.

Any chance we can get a part number and supplier for the linear slide?

Not sure which carraige is the one makerbot has picked - I couldn't find the dimensions of the various carraiges, but presumably it's one of these.

Finally! A printer that really works!!

This is amazing! Is a printable version in the works?
