I'd be most grateful if someone could detail the teeth count on the idler and drive sprockets. Many thanks, mcmiley

This data is on the wiki under diy mechanics. I am replying on my mobile so I don't have a link. On that page are McMaster links, but you can get these from China for a lot cheaper.

The drive sprocket is a 10 tooth #25 roller chain sprocket with an 8mm bore for the motor.

The tooth count on the idler really doesn't matter but is also a #25 roller chain.

I am trying to figure out what the motors and encoders are. Are they GW31ZY's with encoders added to them or A58SW555's with hall effect encoders?
