I've been studying the information and videos on the OX CNC build. I am very interested in building one with approximate footprint of 750 mm x 750 mm and using a Dewalt DWP 611 Compact Router. Has anyone else tried this? Will a machine scaled to that size be rigid enough to be accurate? I was wondering if there was a calculation to determine the X-gantry V slot rail length if the X main frame rail was 745 mm long. (I am assuming that I will lose a little length when cutting the rails.) Another question: Can the V slot rails be cut on a table saw with a carbide tip blade? I have a very accurate table saw and I can control the angle of the cut. Another question: what is the diameter of the Nema 23 stepper motor shaft? I was wondering which flexible coupler to order. Also, would it be advisable to get an electronics package with 4 stepper drivers and run two for the Z axis? Thanks for any help you can offer!
Perhaps best to obtain your stepper motors and measure the shaft diameter before ordering the flexible couplings. They should have a shaft diameter of 1/4" but I have some steppers (sold as NEMA 23's) with 6mm diameter shafts. Tweakie.
