Development:McWire Successor

Intro

Out of all the RepStraps designs currently available, The McWire cartesian robot which has been for some time the recommended RepStrap for those unable to obtain RepRap printer parts. Unfortunately the McWire suffers from a number of problems which can be frustrating for new RepRap builders. This page is here to solve the problems the McWire has and consider the Successor to the machine.

McWire Shortcomings

Speed The McWire is slow. This is due to the screw drive. This could be replaced with a rack and pinion, belt drive, or a wider-pitch screw.

Measurements The recommended method of measuring, cutting and drilling is to print out stickers which have markings on them, and place the stickers on the materials. Stickers can be easily misaligned, and printer variances can result in missized stickers.

Structure The McWire is built on a 3/4" pipe base that is screwed together. Black Iron or Galvanized Steel can be hard to drill, and is not always easy to position correctly.

Proposed Replacement

Based off of the WolfStrap design, utilizing a simple wood structure and common drawer slides for linear travel. This design makes for a quickly-constructed cartesian bot allowing for a builder to get up and going quickly and easily.
