Re: [CAD_CAM_EDM_DRO] Video of the G203 Vampire running a cnc retrofitted Mill drill

I used the 452 oz in MCG IH34110 stepper motors that I sell. I also tested
the 762 oz in IH34112 stepper motors and they were fine also but I think
overpowered. I switched back to the 452 oz in motors.
I used a 3/1 ratio timing belt drive only because I use and test this
machine with various motors. The motor mount is set up to take C34 or Nema34
motors and with an adapter plate could run nema23 motors.
I used 5/8"D .2 pitch 5 TPI ballscrews from McMaster Carr but would
recommend the Nook over them.
I used two ballnuts on the X axis on each side of the ball nut drive block
so I have zero backlash. The Y axis also has two ballnuts. The Z axis uses
my "solving the mill drill backlash problem" eccentric bushings on the
pinion cross shaft for .002 backlash.
Other than that it is stock except for the link belts on the power head
