From the look of your sprockets and chain you'll not be doing anymore cycling...😁

The tricky thing with chain drives is that the smaller sprockets give you terrible cogging and the larger sprockets give you enormous travel per rev requiring expensive low backlash gear boxes to get any king of resolution.

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.

If you are serious at this you could design in Fusion360 it is free for hobby use, a big learning curve but it has CAM built in so you could use for generating the gcode later on.
There are plenty of tutorials on it. like https://www.youtube.com/playlist?lis...Alt9yzBIp84sD8..Clive
