Ok I got bit carried away with the Dollo Z-axis upgrade, it will be 2x120mm which means that the max z height is about 35cm. one z-screw and z-rail glued together, other z-screw in jig waiting for the glue to cure. I'm pleased how straight those parts are, seems that the jigs help a lot.
More parts to be printed and assembled. Also need to redesign the z-motor mount, current solution is not very stable.



Prusa/Dollo hybrid design is also progressing well. Most of the frame parts are designed and started printing them. Using grey and white PolyMax PLA for most of the parts, along with black PETG for the motor mounts and X-carriage parts. Quality filament does have it's good points; it's easy to print, no jams even on all-metal hotends. With same exact gcode, cheap PLA's cause problems.
