After a weekend of heavy tinkering, I finally got the printer to spool a fair amount of plastic through the nozzle. The only bit I have left to finish now is the print bed, endstops, and the final bits of wiring/calibration - and then all of the optional bits, like insulation and taping the motor to reduce slip.

| The very first stages of the extruder assembly - the clamp on the right grips the plastic filament tightly. The grub screws (in theory - not on my first run!) hold the hot end in. |
 |
Later stage of the extruder construction - the big cog is driving the bolt, which in turn drags the filament through.

No photos of the rest of it yet, I simply didn't have time - the SAQ isn't exactly the quickest form to fill out...
