I thought I would show another video of the nozzle with hand extrusion.

The thermometer has poor thermal contact with the nozzle so shows a few degrees off what the actually temperature is.

The cold end of the extruder is about 30' celcius.

The power was removed at the end of video to show the thermal storage of the hot end, it seems to be able to extrude about 166mm of 0.52mm polyamide filament from the nozzle after heating power is removed (the nozzle was drilled with a 0.35mm drill).

I just started working with a "deffective Stratasys 3000" and im having problems but im new to this. Do you know of any issues that would cause the abs to continue to extrude small amounts while the support is being set down? It is causing build up on the front and back of the in and out on the print head.
