Hi folks.
I have the 42-40
BJ42D22-23V16
(LOT NO.201227C) MotorHere is the info I could find: https://www.reddit.com/r/klippers/comments/s4px5x/comment/hssi4sy/?utm_source=share&utm_medium=web2x&context=3
However, as the user @MaxMishchenko says above, it's 1A, that is, it's a renamed: BJ42D22-44V16.
It came with my Ender 5 Pro, 4.2.2 motherboard and TMC2208 (B) drivers.
I have no idea what company makes these motors though. Would be nice to know for support reasons.
Hope someone finds this useful. Most Creality firmwares I have tried put this motor in reverse when printing (feeds filament AWAY from the hotend) so I am compiling my own firmware to fix this.
