That's a good point. I've run the all metal extruder on my printrbot for the last 6 months, and with a properly tuned stepper, the heat hasn't been much of an issue on longer prints (6 hours or so) I would probably run some of the cork insulators between the extruder and the stepper, and if need be, switch out the MakerFarm stepper with a printrbot stepper (as they seem to run a bit cooler) As it is, my current stepper on my MakerFarm hasn't gotten too warm, certainly within acceptable limits (after tweaking the stepper pot of course)
