This has been great progress. You will notice the extruding filament may seem a bit thick. I've a 1mm hole in the current nozzle, but now that I have it running in a very basic fashion, I'll swap it out for a .5mm nozzle and see how that goes. The extrusion tests in the video are with a RepSnapper manual "Run Extruder" settings of Speed=2000 and Length = 780. These are completely arbitrary units of measure I'm sure, as there are so many other factors at play here, i.e. gearing ratios, the nozzle hole diam. I'm going to have to do a bit more reading now that I have an extruder to test and calibrate! :-)
Thanks for viewing!
