So I am finally getting around to the new build. I have the parts and hardware with exception of some screws.

Servos are Sanyo Denki 250 watt 32 V 10 Amp with 1000 PPR encoders
Geckodrive G320’s to run the motors
Ball screws are 1605’s
THK SHS20V rails and bearing blocks (2 per rail)
Structure will be aluminum extrusions 50 x 50 mm and 100 x 50 mm
LinuxCNC will run the system
Initial spindle... a Bosch Colt router, will change to a 2.2kw water cooled brushless in the future.

I have the use of a Vision 4 axis (XYZA) to make parts like motor mount plates and such.

I plan to put the Y rails and ball screws at the height of the X bridge above the table. The Z axis will have the rails moving with their bearing blocks attached to the X carriage making the Z assembly more rigid extending down with a bit over 6” Z axis travel.

2 chunks of the 100 x 50 mm extrusion for the X bridge, and 2 more for the Y rails.
The 50 x 50 mm extrusions for legs and table support.
Vacuum table made of Corrian with 1” square slot grid (rounded corners) using neoprene gasket cut to length for the job. Pieces of MDF lay on the grid as spoil board (edges sealed) to hold the workpiece.

More to come as I begin construction.
Comments are welcome.
