Mini Mil Y axis CNC conversion

This is the Y-axis conversion of my Harbor Freight mini mill to CNC. Print everything with 100% infill. Use 2, M6x25 bolts to secure the print to the mill through the pedistal.

A suitable Oldham coupler can be found here: https://www.thingiverse.com/thing:2649144

Use a thrust bearing (26x13x9mm) between the printed coupler and the mill - this lowers friction when you tighten it down. Machine the coupler to fit (similar geometry to the printed part) and machine the stepper interface part. More details at my blog. http://harborfreightcnc.blogspot.com
