Overview
This RepStrap is an attempt to create a simple cost effective design. The objective is to create a kit that has all the hardware needed for xyz motion. Steppers, electronics , and an extruder can be added to complete the printer
Design Objectives
- 5 ply 6 mm plywood construction
- 8 mm steel for linerar motion
- 8 mm LM8UU bearings
- 200 mm x 200 mm x 200 mm build area
- Spectra fishing line drive
- Fabricate mechanical hardware in less than 2 hours
- Completely Open Source
- Minimal part count
Current Status
Progress will be slow due to the need for employment. The development of a router/mill CNC files is in progress. File:Emount.jpg
