Re: [CAD_CAM_EDM_DRO] ball screw or belt drive?

zbadone: You have a NAME?

Some "in here" may-well disagree, but I don't see the point in trying to do
"precison" work with computer-control if the MACHINE will introduce slop and
backlash far in excess of "everyday capability". Chains won't cut it, unless
you will be making just those notches in the ends of logs for log-cabin kits,
etc.!

Think BALL-SCREWS! For the smallish WW machine you describe, ACME with
Turcite preloaded nuts might do, if you use at least #23 bipolar steppers, or
#34. But I'd go with 3/4" dia. ball-screws with at least 0.2"/turn pitch, if
not 0.5"/turn!

You do NOT have to use clean-room-ground screws! Rolled ball-screws will do.
See Ball Screws & Actuators (company) in San Jose, CA. (sorry, no further
address).

Lotsa luck. Jan Rowland, Troll
