That is quick! The SE only advertises a max of 250 mm/s with 4,000 mm/s^2 accel, so that is pretty crazy.
The official marlin-based firmware also "only" goes up to something like 200mm/s and 3000mm/s^2 for my model, but I've flashed klipper on it which has given me more control so I wasn't constrained by the limitations set by the manufacturer in the firmware.
I was able to push it to 500mm/s print speed and 11000mm/s^2 accelerations, but small details started to suffer and I was getting too much ringing. For simple large prints I still use it though if I need a quick-ish prototype.
Surely that wasn't with the stock hot end though. I've done 400 mm/s at 12k mm/s² but I only achieved enough flow after upgrading to a KE style hot end Proof
Using a V6 style hot end with 0.2MM brass CHT nozzle. According to the flow test method CNC kitchen uses I max out around 54mm^3/s @220°C. I can only print that fast on larger prints though because my cooling can't keep up on small prints.
Figured as much 😜
