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 Finer Quality Prints
Upgrading the standard 0.5mm nozzle which comes with your Huxley kit to the RepRapPro 0.3mm nozzle will produce finer quality prints at 100 microns or better.
(See: eMAKERshop, 0.3mm Stainless Steel One Piece Nozzle)
- 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 accuracy, especially when printing circular or curved objects.
(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 reconfigure the firmware's steps/mm setting.
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.
