Ron,

I am running TCNC on PII-330 MHz computer. I tried to install Mach2 on an
AMD Athlon 900 MHz once but couldn't run it. I'll give it another try on a
P4 pc again and see if I can get used to it.

satisfied with smaller servos and larger reduction. And others use larger
servos. I'm running 40 lb-in servos on all three axis with a 2.5:1
reduction. Some would say this is way overkill however, I just ran a
production run of 340 1018 blocks and had to remove the middle of the block.
An area of 2.5"X3"X.875" deep. Using 3/4" roughers and 5 passes on each. 5.5
minutes each to complete. Smaller servos would've took longer. Thats the
difference. The X motor doing most of the work barely got warm after 10
hours of running continually. I'm sure it didn't do the ballscrew any favors
but that all has to be weighed in to the profit made. Although a 28 lb-in
servo would probably had enough torque to do the same. 40 lb-in on X and Y
are a bit much.

decided to upgrade to ball screws and servos. What size motors would be
suitable for that purpose. I'll go with geckos and turbocnc. I would
appreciate help from anyone who has alread done that as this would be my
first experience with servo motors and drives.
