Cheap 3D Printer

Question

Hi to all,

I would be very grateful if you answer my questions?

I have decided to buy a printrboard from ebay and several stepper motors:

Printrboard	£ 77.59	1	http://www.ebay.co.uk/itm/PrintrBoard-Electronics-for-PrintrBot-Prusa-Mendel-or-your-RepRap-project-/271019776730?pt=LH_DefaultDomain_0&hash=item3f1a099ada
5V Stepper Motor	£ 9.60	3	http://www.ebay.co.uk/itm/DC-5V-Gear-Stepper-Step-Motor-with-ULN2003-Driver-Board-4-Phase-Unipolar-/140956394738?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item20d1a7e4f2

Total
£ 87.19

For the hot end, I am using the 3mm ubis hot end. However, do any of you know which hot end is better - ceramic or cartridge? Thanks

Please may you tell me how I can be able to wire up the hot end and the stepper motors to the printrboard? Thanks and do I need the motor driver with it?

NB: I am using Ben Heck's Design forthe Double Decker 3D printer

Here is a stepper motor taken apart Canon MP190 Printer:Can I use this motor for the printer? Will the driver work. It has four wires.

Thanks again

Tim

You know I actually got that same assembly from a surplus store and tried making a plastic extruder out of it. It worked, but the motor got very warm. If you can get Nema 17 steppers for $15, just use those. They work, and they have standard mounting. You can waste a lot of money trying to do things cheaply.
