Re: Which extruder to choose?

I see! The 5:1 geared nema stepper is a bit over geared right? So it slows retraction a bit? Seen anyone try to gear it down to 3:1 if that's even necessary? Im hoping an astroyn damper will fit too but it probably won't due to it needing to be close together.

You would be doing double duty and getting the worst of both systems, the complexity, ineficiency, and hassle of a geared extruder, and the added cost of a geared stepper all to accomplish what you could do with just a geared extruder.

That is the reason I use printed gears. 5:1 (common for geared steppeers) is too much. Your retract speed will be low (probably below 50 mm/s). My opinion is one should have retract speed at least 100 mm/s for ABS with 0.5 head.

I agree 3:1 is closer to ideal, but from a simplicity standpoint, the geared stepper is just so much easier to live with on a day to day basis.

If we could get a 2:1 or 2.5:1 geared stepper, I would jump all over it.
