I read on the GenXlab blog about using your cnc machine as a 3d printer that they recommend
ed the Maker Gear stepper plastrude
r. They said it was bullet proof . So far i have used a couple hundred feet of abs filament and found their recommend
ation to be accurate. The heated element does have an insulatin
g compound around .37mm the noozle where a thermocou
ple is embeded. That if followed by kapton tape and then two fiberglas
n boots. Work great.
Ditto..Aw esome! That's an interesti ng asteroida l nozzle. I'm guessing has to do with temperatu re control. It looks like insulatio n used to contain the heat for accurate sensing.
