This is the place to describe improvements to RepRapPro Huxley
Huxley Mini-Spool
A horizontal mini-spool to store a small amount of filament right under your Huxley.
Mattroberts' Huxley Paste Extruder
Replace the hotend with a 5ml syringe.
Mattroberts' Huxley Carriage
Adds nuttraps to the carriage, so you replace the self tapping screws with metal screws.
Achieving the Golden Standard - 100 microns
- Who exactly defines what the "golden standard" is? --Traumflug 09:22, 10 June 2013 (UTC)
- It is the name being adopted by the RepRap community to define the 100 micron benchmark before high cost or highly specialised engineering equipment is required for calibration. --jlbarchive 00:33, 11 June 2013 (UTC)
Upgrade the standard 0.5 stainless steel one piece nozzle which comes with your Huxley kit.
(See: eMAKERshop, 0.3 Stainless steel one piece nozzle)
Installing the RepRapPro 0.3mm nozzle will produce finer quality prints at the 100 micron golden standard or better.
- N.B: A feeler gauge is required to accurately calibrate the nozzle/bed, also print time is substantially increased.
PLA vs. Aluminium Pulleys
Upgrading the X & Y axis printed PLA pulleys with T2.5-16T aluminium replacements substantially increases print quality.
(See: eMAKERshop, Think3DPrint3D)
You will have to remove the small flange at one end of both pulleys (using a metalwork lathe) in order to mount them on the Huxley's drive shafts.
- N.B: Don't forget to change the firmware from 14-16 teeth step count.
Smooth Rod Lubrication
Optimum carriage travel for all 3 axis can be obtained by applying "Super Lube" (Synthetic Grease with PTFE) to all smooth rods.
It provides a substantial improvement over white lithium grease, as it provides the lowest coefficient of friction.
- N.B: It's costly for a relatively small quantity.
DIY Cooling Rack
You can make a small wire (glass bed) cooling rack by obtaining a 120mm diameter PC fan guard.
Folding down all four circular lugs creates small support legs.
