Hi guys, is there a 'go to' belt option for servos that provides minimal backlash and is not out of this world expensive? Perhaps what the 'pros' use on some VMCs?
I have read through some of the gates catalogue and I just don't want to read through lots of catalogues (like goodyear might be next) working out each manufacturer's sizing process before I arrive at some universally agreed on best option like "just use HTD 5 (a belt type I have seen a bit of)" and "read this catalogue".
My servos are three 750w 3000rpm and my mill is a RF-45 (I know a little big for the table).

Also, for spindle I bought a 1.8kw 3000rpm servo, I did some sizing calcs using the gates catalogue for a 'v' belt but then realised I couldn't do rigid tapping. Should I use a timing belt for the spindle then? Any recommendations here for a quieter option?

Thanks, any pointers appreciated!
