does this mount on a parallel vertical X axis or on Parallel horizontal X Axis like the RichRap Version

Could you please tell me where I can buy these metal components such as bearing, and what is the proper dimensions of them ?
Thanks a lot~

wow Can you make an extruder out of a mini glue gun? or is there an Issue with Filament control....

People have done so...I once watched a YouTube video with one.

Can you print with play-dough?

Never tried play-dough, but it should work as well as clay or marzipan.

What value is used for e_steps_per_mm?

What is the GearRatio of the extruder?

Maybe you can use a formula like this:
e_steps_per_mm = StepsPerRevolution /MicrosteppingOfControler GearRatio SyringeRadius^2 /NozzleRadius^2

Thanks a lot. Great stuff.
