Totally get that! Been doing countless searches on Sprockets and sizes to see what method would be best to resolve travel distance to rotation. Thinking i'd use some sort of gearing to compensate.

small drive cog on stepper to a large cog attached to my "control bar" which would equal a zeroing out of the exterior cogs that connect to the chain.
