Duplicate Extruder Mechanism Mk2 Operational

Ash and I have just got the first bit of Polymorph extruded from the Mk2 that we're building from Adrian's parts. We're using a TIP31C to switch the heater on and off, supplying the switch current from a simple pulse output on a PIC. Motor is operated manually by the two of us. Not built Adrian's AD stuff yet, hope to have something together by LinuxConf 2006 in a fortnight or so.

The nozzle exit hole was 0.5mm diameter and the outflowing Polymorph between 1.5 and 1.4mm in diameter - somewhat more than expected. Our average nozzle temperature was 105C.

I've put a page up in the Wiki on this one because it uses halved washers and Polymorph to make the half-round bearings called for in the design.

Vik :v)
