This is my attempt to build a machine that was fast and accurate for less than £100.00. I've more or less achieved that but you need to shop around for the parts and the Igus samples service helped a lot when it came to the bearings for the X, Y and Z carriages. That said, with a group buy, it comes in at the budget even if you purchase the bearings. The reason for using them was to enable me to use cheap rods for the carriages. I used 8mm and 10mm OD steel tube from a local DIY shed but you could use aluminium, or anything really. The core xy lines are 100lb spectra fishing line and it runs on bearings throughout. There is a full video walkround of the completed machine here http://youtu.be/_oyftJF3l34.
