After long pause I came back to build my new CNC. I almost made electronic driver to it. Pictures of it will be available tomorrow. Next think I made was Z axis. I decided to made it from 10 and 12 mm plywood. I used 12 mm line rails, and 6 line bearings. Screw used it TR 10x2 with brass nut. Margin on it was good, but later I will cut it and squeeze to get margin elimination. I have almost 150 mm of operating range, but I am think to reduce it to 120 mm to get better stability. Step motor used have 1,2 Nm, and power is direct transfered to screw by coupler. Everything is prepared to hold KRESS (I think that I will use 1050 model). I try my KRESS to it, and it fit tightly. I take pictures before final touch of file and varnishing.
