Difference between ST and HF
Compared with ST, HF version has higher flow(just like its name), like V6 volcano.
It means if you want print at 150mm/s or higher and use a 0.6mm nozzle or larger, you should choose HF version.
Or ST is fine, in our test, it can print PLA/ABS at 150mm/s with a 0.4mm nozzle.
In other words, if you don’t know which one you should choose, then just go with ST version.
