http://www.jaycar.com.au/Tools-&-So...r-Power-Tools/Arduino-3D-Printer-Kit/p/TL4100 Just finished building and calibrating it. Sending my test print in now! Building it was fun, you actually get WAY more nuts and bolts then you are actually need which threw me off for a while. I didnt't assembly the power supply in the top and im using a seperate 12 volt supply. After calibrating it which was actually pretty easy, the first print is coming out now. Will post pics when its done. edit: responds well with slow feed rates. 1/4 feedrate makes it smoooooth.
