I meant that the smaller setup that I posted would put more stress/torque on the motor itself to extrude the filament.
Since it has no gearing to help it out. I should have worded that better.

Also makes sense what you said about the resolution also though. Didnt think about that.

As for the gears being easily printed at home? not for me so far. haha
I have tried printing the small gear 4 times now, last time was the best, but some teeth are still messed up.

I need to figure out why I dont have crisp edges. My 90 degree corners on boxes are a bit rounded, and my over all perimeter is not all that smooth.
Thought it was loose belts but they seem tight enough. I think its the nozzle oozing. Seems to do it where the nozzle pauses or slows way down during printing.
