Re: [CAD_CAM_EDM_DRO] RE: Rong Fu RF 45 vs RF 31 CNC probe- Help!

Andy,
Can't comment on the machine itself, never seen one or the other 'in person'
and I have no experience with more than 3 axis.

Regarding the drives my vote goes for the Geckos. www.geckodrive.com Very
good stepmotor drives. I have three G210 myself and they work perfectly. If
you're not in a great hurry they have a new drive soon to be released called
G204 that seems to be THE step-motor drive.

If you're going for step & dir servos Geckodrive have that too and in you
should also take a look at Rutex. I have no personal experience with the
Rutex drives but they get good comments around places like this one.

For true closed loop analog servos I _think_ that EMC and the Servo-to-Go
card is the only way at the moment.

For breakout boards Bob Campbel has one that's been getting good reviews,
Google his site and check it out.

Good luck!
/Henrik.
