Topic: Limits for gearing on an extruder?
I'm going to be ordering a geared stepper motor soon for my bowden. I don't think a higher ratio will affect actual printed extruding in a negative way since its so slow anyway. I'm mainly concerned about the retraction aspect.
At the moment I'm looking at either 27:1 or 14:1 stepper. I can go to 32 microsteps, which if my math is right would give me about 5208 steps per mm for the extruder. Is there a good way to figure out limitations running some numbers they have detailed for the steppers?
Here's the link for one I'm considering :
