Hey, please checkout my new CNC X&Y motor mounts for the MicroMill, including bearing block and stepper mount. This is for X1 mills. NOT X2. I have attached 2 jpegs with dimentions, and the CAD file. Pressfit 8x20mm bearings in the bearing block. Use 1/4-20 screws to attach the motormount to bearing block, and use spacers to space the two out. 8-32 screws are used to mount the nema 23 stepper to the motormount. This is direct drive. A 3-1 belt drive version will be released soon. Please check this out and add comments or modifications and LMK what you think of it. - Zack
