RR-Evo Delta 3D Printer - [E2] upgraded with Rostock parts

thingiverse

This is next step of RR-EVO's evolution. Moving plywood parts replaced with 3d-printed. Previous step:RR-Evo Delta 3D Printer - [E1] plywood version Next steps:RR-Evo Delta 3D Printer - [E3] hot-end mount Description Once I got the device printing I started making parts to replace plywood ones. All the parts are of original Rostock design except vertical carriages. The following modifications were made in carriages: added couple of 'ears' to hold end-stop screws at positions that correspond plywood version of carriages; removed standard belt holder (instead I developed separate tensioner); As you can see on photos, quality of parts I got was quite awful. That can be explained with several factors: lack of experience in 3d-printing; very poor calibration of the machine, not only extrusion but geometry also - that's lack of knowledge of delta mechanics; Anyway, I got significant improvement with replaced parts. The tensioners fastened to carriages in place. I used M3 bolts and 'glue' (ABS dissolved in acetone). I tried to develop carriage with integrated tensioner, but that design I got would be hard to print. So I decided to leave it separate. The 'glue' was also used to fix some defects of parts and to fix nuts in different places. Along to the improvements, some major issues still present in this construction: the carriages are still on two linear bearings (swinging) - better to use carriages sitting on 3 bearings (or at least 2 longer bearings); due to bad calibration of geometry, printed parts had wrong and inconsistent sizes, that brought significant troubles into calibration process of updated version - spend as much time for calibration as you can to get better result. I was impatient... that was stupid.
