Re: [CAD_CAM_EDM_DRO] Timing belts

https://sdp-si.com/
SDP/SI 68,000 Master Drive Component
Database Includes Free 2-D drawings and 3-D Models

they have a java applet for choosing pulleys and
belts.

i'm gonna try it on a lathe (or 10)
but not a 4 ft span.
i think not many ppl use twin lead screws.
i'm using 90 tooth pulleys.
bigger pulley means any belt slop is smaller
proportion of linear error

plz keep me posted on your results!
