Built a gantry type cnc machine as an exercise, not rigid enough for
some clock parts I would like to make.
I have bought an SPG9512 from SPG Tools and I am extremely pleased
with it's tolerences and rigidity. My research on DRO's led me to this site,
particularly the use of chinese vernier calipers in a simple DRO setup.
Thinking of going the Shumatech way at the moment, but will search
for awhile for alternatives.
Regards
Dave
