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

4x free wheel sprocket £2 or free of you have shed load of spare bits like I do. As for bike rides here's a pic of my little bike. Also the results of stupid tinkering.

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.

I'm still alive.
Okay so I've built, destroyed, re-built over and over.
This is where i am now.

OK so where am I.
After the weight limit issue. Rather than buy more powerful motors I scaled down.

Now have a rag tag machine with all 3 working axis.
No spindle as of yet, not even my test tool.

Videos and photos to come soon.
Brace yourselves as she's proper ugly.
