Hey Bill, hey Jan,
that’s what I plan to do (when I will be ready one day), but I expect it to be some work time to do it.
Although the design is simple. Actually you only need to take off the X-35 and once the X-50 aluminum extrusion profile, then the chrome-plated hardened steel hollow shafts, which are probably from mitsumi, just like the ball screws and the linear bearings, there’s the CAD models surely there, and then you need to take off the Z assembly (Z-16 vs. Z-20 differences). The stepper motors dimensions are available (Standard Series Journeyman X stepper motor vs. Elite Series Closed Loop Stepper motors).
So if you want to copy the machine, I don’t think that’s very difficult, just like assembling a 3D model from your own measurements and 3D models of the respective manufacturers of standard parts.
