hiya guys.

I've been looking at the steps per mm and I am perplexed as to where the 96 steps per mm came from.

using a stepper motot 1.8 deg with 1/16 micro stepping should give me 3200 steps for a complete revolustion. The circumference of the feed gear is 10.7mm

how can I calculate the steps per mm?

cheers

If the math doesn't make any sense, then go ask your manufacturer :D

The circumference is 10.7mm... or the DIAMETER is 10.7mm. I'm thinking that your circumference is more like 33.6mm......
