Has anyone ever used .250 pitch chain and sprockets for their x axis over belt drive? I like it because it doesnt stretch or shrink over time compared to that of belt and still have good rapids.
I raided about 30 feet of chain from three "destined to the scrape yard" 6 ft. plotters (its amazing whats in plotters for parts and pieces. I got my drilled and tapped 5ft 10in 16mm rails out of one plotter) and various sizes of sprockets and I'm thinking of using it over belt.
The chain fits nicely into the groove of 80/20.
One question I have about this is the size of sprocket to use. Is there a formula to determine the distance of travel per rotation for various size diameters.
I could probably quite easily just set up the existing sprockets and measure the travel of the chain per rotation, but suspect its probably going to give me an odd distance to divide for stepping. I'm wanting to get the correct sprocket size for easy stepping calculations. I'm just wanting plain ease over all.
