Personal Fabrication
I’m really enthusiastic about the reprap project. The whole Idea of having a printer that can print functioning parts, just on your desktop is .. well.. cool. The reprap is a machine that can replicate part of its own parts. However, to build one from scratch you get a certain ‘bootstrap’ problem.. Hence you have to start out with a ‘repstrap’. Or simpler said, build a 3d extruder/printer/milling machine from scratch so you can make the parts for a reprap machine or any other design.
This is the first post on this subject, the X-axis of the machine is more-or-less finished. Parts used are:
- M5 threaded rod
- stepper motor and bearings from 5 1/4” diskdrive
- MDF and screws
- two slider-bearings from a kitchen drawer
Normal ball-srews have a larger pitch, so the cart can travel faster. This cheap solution using normal screw end is probably going to be rather slow… Oh well.. you have to start somewhere.. I made this part in one evening in the lab with the Spullenmannen, after a toko on OpenFrameworks and ComputerVision.

[...] time ago I tried rep-strapping using 5-1/4” diskdrive motors and MDF wood. (see here). The motors turned out to be way too weak, the M5 thread way to slow. Perhaps a larger thread [...]
