Z motor on the left, 2/1 gear between motor and OEM 16 tpi 3/4" screw ATM. This is the screw being discussed. HF micro-mill with expansion tables from LMS, home made Z drive, some early pix of it on my web page. Std (but longer) screws on x&y. Lotta miles on it. Plastic spur cut gears in gearbox have been totaled a couple times now. Anything I left out, just yell Ben. Thanks.
