Central Machinery 47158 / Sieg X1 Mill CNC Conversion Adapters

This is an adapter for a Central Machinery 47158 / Sieg X1 Mill to a NEMA 23 Stepper Motor. I've currently modeled the X/Y and Z mounts on the mill, the coupler, the stepper motor, and a custom X/Y bracket. After fine tuning the X/Y bracket I will create a Z bracket and add it to this project.

Coupling:

The coupling was purchased from probotix as well, but they are carrying a different coupling now.

Changelog:

14-June-2015: Increased holes by 10%, Shortened distance from mill to stepper, cut away a cylinder to allow room for the head of the bolt going into the mill, slightly decreased the cross-cut cylinder

20-June-2015: The updated X/Y mount is working well. The Z mount needs some adjustments. Need to increase hole size slightly, increase the spacing between the two parts where the bolts go in, and need to shorten the overall height.

The XY Brackets use 2 M6-1.00 x 50 Hex Cap Screws and 4 M4-.70 x 30 Hex Cap Screws

The Z Bracket uses 2 M6-1.00 x 70 Hex Cap and 1 corresponding nut (one of the bolts is too close to the sidewall for the nut to fit on, but the hole in the machine is already threaded, so it is secure).

When printing, print it horizontally to give it strength, otherwise it may break between layers.
