Crank it up to 201% on my old I3 clone. 120mm/sec!
This printer started out 10 years ago as an "Alunar M508". The only things that remain are the main board and frame, everything else has been replaced/reinforced/redesigned. It's a workhorse. Still manually leveled but it runs like a dream, can crank this thing up to 120 mm/sec and still get reliable results.
