Re: [CAD_CAM_EDM_DRO] bridgeport quill screww

Daniel,

I am using 550 oz-in (probably) Vexta 5 phase motors on all three axis with
Vexta UDX-5128 drives bought from the local junkyard. 2:1 reduction on all
three axes with acme screws. Guess I'll have to increase the ratio on the
z-axis. Reduction is through timing pulleys and belts from the same
junkyard. I can post pictures on a geocities website if you wish. Controller
is Turbocnc on an old Pentium II running in DOS mode of win98.
