In this video I redo my speed test with larger object, because the one from my first video was with too small object to reach the max. velocity of 200mm/s. The speed test is just out of curiosity, I don't intend to print with this speed. If you look at the cube closely you will see that allthough it printed fine, there is some ringing (gosting) on the Y (my belts are tight), and I think this acceleration/speed is the limit for good print quality on a printer with moving bed.
I get very nice prints at 120mm/s infill, 100mm/s inner wall, 60-80 mm/s outer wall depending on the model and 2000 acceleration (infill and inner) and 1500 acc for the outer wall.
I show also two other prints - the Rancor from thangs.com (heavy and tall print) and a torture test with a latice cube (z-hop at 1mm).
