My YouTube video: Stock mainboard, stock steppers, almost stock firmware(only changing max temp of the hotend)I've changed every printed part into Polymaker carbon fiber nylon(PA6CF) and added some mod, which is listed down below. Those changes helped me to achieve this insane speed and I think there is still more headroom to go. But in the meantime, I don't think that the stock configuration will be unable to bear this setting. I think they'll just be Some artifacts on the surface of the part, but I'll still keep up with the speed. However, there's a limited factor: the volumetric flow rate of the hotend. I'm using Phaetus dragon high flow hotend and a CHT nozzle so that won't be a limiting factor for me, but if you are using standard V6 configuration, I think it'll be better to be conservative about the flow rate. And I think there's also a very important mod that is the anti-vibration feet because they serve as a damper for the machine, and it helps to reduce a lot of ringing.
