Mattroberts' Huxley Paste Extruder
Revision as of 15:22, 3 August 2012 by Mattroberts (talk | contribs)
Everything here is new, but is influenced by RichRap's Universal Paste Extruder. This design will work on a RepRapPro Huxley.
What you need
- 1x each of the RP components
- 1x NEMA12 Motor (I used a SY28STH32-0674B from zapp automation)
- 1x XL timing belt
- 5ml syringe
- 5x 624 bearings
- 1x M4x36mm studding (a little longer will not cause problems)
- 1x M4x58mm studding (a little longer will not cause problems)
- 2x M4 nyloc nuts (M4 nuts and super glue will work)
- 7x M4 nuts
- 3x M4 washers
- 2x M3x8mm bolts (longer will cause problems, but can be cut from 12mm bolts)
- 2x M3x12mm bolts (longer will not cause problems)
- 2x M3x25mm bolts
- 6x M3 nuts
- 4x M2.5x6mm screws
How to assemble
Firstly, add the 4 short M3 bolts to the syringe_mount. The 12mm bolts are used for the belt clamp, the 8mm bolts to attach the bearing_mount: this photo shows 20mm bolts used for the belt clamp, so it is even easier to see what goes where
Then, attach the motor to motor_mount using the M2.5 screws. Make sure that the flag is as long as your motor, if it isn't the X endstop on your printer will not trigger.
