Mini Mil Y axis CNC conversion
thingiverse
This is the Y-axis conversion of my Harbor Freight mini mill to CNC. Print everything with 100% infill and secure the print to the mill through the pedestal using two M6x25 bolts. A suitable Oldham coupler can be found at 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, with similar geometry to the printed part, and machine the stepper interface part. More details are available at my blog, http://harborfreightcnc.blogspot.com. To jog the x and y axes, watch the video at https://www.youtube.com/watch?v=NLzsbjZJpv0. The X-axis conversion can be found here: https://www.thingiverse.com/thing:2586512
