Taig retrofit

I am presently retrofitting my little Taig mill
with 180oz steppers and Gecko drives on all four axes.
I expect even greater accuracy with the microstepping
and, at the very least, the bigger stepper on the Z
axis won't have as much strain as the old 111 oz
stepper did pulling the Z axis motor and spindle up.
Some of the organic looking jewelry I design is
entirely built up by hand but having been a jeweler
for
some 35 years, I can tell you that CNC has made a
great difference in my life and I love the learning
process necessary in CNC!

I had a similar idea; but I'm retrofitting a Taig with Geckos and servos.
I'll have to make new motor-mounts, since no servos seem to be made with
NEMA 23 mounts, but having closed-loop speed and accuracy should make it
worthwhile. I got my Geckos a couple of days ago- they sure are small! I'm
wondering how hot they get when in use? Should I be attaching them to a big
heat-sink and fanning them?

I do organic-looking jewelry myself, but some of it is done on a CNC mill.
It's a heckuva tool for a jeweler.
