Status
The Huxley is in printing condition. Several prints were completed on it. The prints are of dubious quality, as we so far have only used it with RepSanpper under Ubuntu. It is unknown whether this sub-par quality is due to the printer or un-tweaked host software. The settings that have worked well for other printers are not quite working for Huxley. Efforts are underway to tweak these. Linked is the current configuration file. File:Huxleyrepsnapper.conf.txt You may need to remove the .txt at the end of the extension for it to work.

Build Notes
Extruder Hose
The huxley extruder uses a hose to feed filament from the extruder to the tip. The extuder end of the hose requires two nuts to be threaded onto it to ensure that the filament feeds in properly. These nuts can be very difficult to thread on, as they're slightly too small for the hose. An easy way to thread them in is to cut the end of the hose to a point, pinch it together, thread the nuts on, and cut the hose flush again.
Extruder Mounting
Because the Huxley has an extruder which is physically separate from the machine, it's necessary to find a way to mount it securely. The Techzone instructions suggest a folding mount using a metal plate on one side of the machine. We didn't have the required parts to make that design, and decided to see if we could avoid using any new parts. By drilling a hole through the hose side of the extruder near the motor, we were able to mount the extruder to the threaded rod frame using an existing nut. This mounting technique requires no added hardware whatsoever, and causes filament to feed in from the side of the machine, which works well for us.
