Introduction

I am an Electronic engineer and had quite a lot of success at work using Ardunio's to build the test systems at work. I thought it would be fun to build a rep(st)rap over the winter 11/12 with my son.

Last year I built a Cruzbike conversion kit (see currystomper on the Cruzbike.com forum)- so hopefully I will get to the end of this project over the winter!!.

I like the look of the Wolfstrap and so may start for that point.

...more later.

Having spent some time looking around the site, I think I'm going to start with a Wolfstrap, I like the idea of using a threaded rod to drive the axis's. However I see at the bottom of the page that stepper are far to slow for this. (Also they generate a system that is too accurate ie too many steps per mm.)

So here is my mad idea (foley!!) a brushless DC motor is actually a course stepper motor, when used with a threaded rod system this may give quite a nice drive system, so my plan is to made a single axis system to see if this is a mad idea or not. I can test out its max hold, repeatability over time and its max force.

If this works out it may reduce system costs quite a lot - maybe it holds out the possiblity of a system making some of its own drive systems too..
