i made 5 sprockets before found a way to trick it into spacing that fit. i ended up making a 31 tooth sprocket with design accelerator then modifying the pattern for 33 teeth then it worked enough but the chain doesn't quite sit down.
so i'm asking for 2 accurate inventor files for these 2 sprockets or what i'm doing wrong.
thanks

I have also noticed that the Inventor geometry for #25 chain is incorrect. I am not entirely sure what it is, but we I attempted to CNC a sprocket using the Inventor model, the chain did not fit as well (so you are not doing anything wrong). As far as what to do, I can only suggest that you consider making your own profile for the teeth and work from there. Take some calipers to the chain and the incorrect sprocket and see where Inventor went wrong and try to fix it manually. If you are short on time however, it may be more cost-effective to buy them.
