RTurnock,
Regarding the extruder motor yes, I've placed heat sinks on mine and have a fan rigged up blowing onto the hobbed bolt/filament area and providing some air across the heat sink. Mine jammed all the time until I got the fan on it. Now I can comfortably walk away and let it print. Longest session has been 5 hours straight. I know what you mean about baby sitting it cause I'd use the same term prior to the fan.
Am excited that I just found this thread and will likely look into printing your parts as I've just started reading up on the delta printers.
