Awesome work!
did you have chance to measure the axis to axis distance ? There is another important design measure to get is the y axis clearance as the nut passes along the z axis bearing housing.
Your yoke look way better than mine, ive just sketch the whole geometry.What ballscrew size are you using ? Are you trying to fit chinese ones ?
Are you willing to share important dimensions or cad ?
thanks a lot , im glad to know some people tryin to do the same type of upgrade!
