I want to thank everyone here for the great posts, downloads and information, this is my first 3d printer so all the help and advice is very much appreciated. I found an instructable by jgschmidt on assembling the Migbot i3 so thought I would post the link if anyone else finds it useful:- Migbot-I3-3D-Printer-Assembly-and-Use /Simonby sihorton - Prusa i3 and variants
