Just starting out the world of RepRap, currently pulling together bits for a Prusa Mendel.
Parts
My parts collection so far consists of:
- Printed Parts including parts for Wade's Geared Extruder from ParCan on http://www.emakershop.com for £75
- Fasteners, Bar and Studding from Bob_balthazar on http://www.emakershop.com for £34
- Bearing from rsoarer on ebay for £4
- Thick sheet set from genesismachines on ebay for £20
Still need:
- Stepper motors, probably from astrosyn_excess on ebay
- Arduino
- RAMPS (Sanguinololu?)
- Opto or mechanical end-stops
- Belts
- Extruder hot end
I have the following extras from the Prusa parts list, some of which are probably for the extruder:
- 2 x belt-clamp
- 2 x bar-clamp
- 2 x rod-clamp
- 4 x pla-bushing (total of 16)
Software
Need to download repsnapper, skeinforge and sprinter(firmware)
Questions
Stuff I have to find out about...
- If I buy a 'loose' belt and want to cut it to size, how do I attach then ends?
- Recommendations for a power supply? What lines will I need?
Answers I got were:
- I thought belts were continuous loop but they're not
- Need to clean up bushings so 8mm rod runs smoothly through
Assorted notes
ABS = tougher, but stinky and hardly enviro-friendly, also takes much higher temps to melt it and almost requires a heated bed. PLA = Compostable, lower temp to work with, but more brittle by comparison and harder to glue.
Experiences
- Some difficulty getting the bearings into the extruder, had a lot of filing down to do to make them fit
