Chaucer - A Vertical 3D Printer
by ronsheely, published
It is modeled after a vertical milling machine. A light and fast print bed moves on the X-Y axis via stepper motor timing belt drive trains. The print head, or extruder is heavier, and moves on the Z-axis via a lead screw drive train.

Chaucer is a derived from an earlier printer designed by David Kennell, posted on thingiverse.com/thing:19891.
When I decided to design and build a printer that would help me develop a deep understanding of the 3d print pipeline, and to provide a test platform for high speed printing with multiple experimental print heads, I knew I needed to model it after a vertical milling machine. David's open source project, which he dubbed the Pocket Printer, gave me a great place to start. David's generous help was instrumental to my success.
The maximum print volume is: xyz = 160, 180, 110 mm.
The current print volume is set in firmware to xyz = 160, 140, 110 mm because I misplaced the heated print bed. I will fix that.
I will submit detailed instructions and files as time permits. If you need something, please let me know.
Here is a video of my first successful print. It's not perfect, but easily fixed. See youtube.com/watch?v=4djXJ5xvO8o
I uploaded the trapezoid foot files in both OpenSCAD and STL format. The scad file makes use of ruler model found at thingiverse.com/thing:30769 The foot is a modified version of the rear feet of the Pocket Printer.
