Mk II extruder barrel test rig operational
You can see the BD681 power transistor on the board lumbered with a large heat sink that I had at hand. The MK II extruder barrel is seated in the vise at the right of the picture.
Once I am satisfied with the temperature control on the barrel I will try doing some melts of our samples of 3 mm polycapralactone filament.
