I’ve done some filament drive gear benchmarking using the Airtripper extruder filament force sensor and graphing software I’m currently coding.

So as an exercise, while I finish up on the drive gear benchmark and review blog post, how would you rank the gears (shown in the picture) according to stable pushing power performance; which gear performs the best to which gear performs the worst?

Note that the performance is based on using direct drive NEMA 17 stepper motor so maximum torque is a restricting factor.

I already know the result but it will be interesting to know if the result is reliably predictable by others without the benchmarking tests.

D, b, c, a would be my guess

3

C, D, B, A

4

As a quick guess, strongest to weakest, I would go for B, A, D, C

5

b, c, a, d

6

b,c,d,a?

7

C

8

strong to weak: D, C, A, B

9

C, A, B, D

10

C, A, B/D (whichever one has a smaller effective diameter) here as well. Simply due to diameter. Smaller diameter means more torque is produced through less motion. Interested in what effect the tooth profiles have on that, and if any of those profiles allow slipping.

D, c, a, b

CDBA. Btw. what’s the torque of your stepper?
