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)
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.
Ditch those PLA Pulleys
- While there might be advantages (and disadvantages, of course) in changing pulleys, I'm not enthusiastic about the commanding tone of such contributions. Every user is free to do what she thinks is best, so showing the advantages (e.g. pictures of print quality before/after) is a much better way to introduce changes. Not to forget that there are always several solutions for one problem. --Traumflug 09:20, 10 June 2013 (UTC)
Obtain and fit x2 T2.5-16T aluminium pulleys to you RepRapPro Huxley’s X and Y stepper motors.
(See: eMAKERshop, Think3DPrint3D)
You should see a substantial increase in print quality, especially when printing circular or curved objects.
- N.B: You will find removing the small shoulder (using a metal work lathe) from one end of both of the pulleys makes it much easier to mount them on Huxley’s drive shafts.
Finally, don't forget to modify the Huxley’s firmware from 14 to 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.
