    Those on the website will be fine. I've used the same grade on several machines without any troubles. However, I'll warn you to now the pinion tension will need to be spot otherwise they'll wear prematurely. The CNC Router parts tensioning is a little aggresive IMO so you'll need to keep careful eye on it.

    yes the cncrouterparts drive has quite a strong spring apparently, read that some have adjusted the pulling position to account for it.... but that's for another post!

    Does anyone use anti-backlash gears for driving racks?
    You think that's too expensive? You're not a Model Engineer are you? :D

    Not seen many on routers. Most routers use helical which is little better regards backlash or they spring load pinion into rack.
