Happy Holidays!!!
I wanted to print a better one, quality wise than the last, to improve my slicing ability. It's a bit boring, but maybe you can find some useful information in the video, at least what NOT to do, lol.
Specs:
ABS 305C, 0.4Tungsten carbide nozzle, .01PA, .02ST, 900mms commanded, flow cap 70mms, infill at 90mms3 according to slicer (LOL), 50K external, 200mms/10K internal bridge, 85mms external bridge, 70K acceleration the rest, 60 square corner, 0.95 flow multiplier.
Stepperonline A6 servos, 100W each (x4), .32Nm torque, 1.12Nm torque peak. Moving mass; 1900 grams total(toolhead, carriages, rails, rail stiffeners, ETC).
Chube hotend, VZ hextrudort extruder with moons 17mm wide motor. Heat break cooling is done via external aquarium pump. Filament is Sunlu ABS and cooling is done with "UfO-N-AtOr".
Input shaper disabled.
40.52 grams call out in slicer, 41.2 grams actual model. I think the slicer is not calculating grams properly! -Math from that says flow should be .934.
0.2 layer height, 2 walls, 5 top, 3 bottom, 15% adaptive cubic infill.
Max acceleration seems to be ~70K before strange issues with extrusion and, of course, slowing down external acceleration improves PA and surface finish.
These type models help considerably with testing maximum's of the printer related to cooling, surface finish, bridging, ETC.
