I would like to replace a NEMA 17 stepper motor for my FLSun SR (it clicks and the rotor eventually slides forward, causing it to offset layers). How do I find the specs for this motor? They aren't listed on FLSun's website and I tried their contact us form. The back of the motor has this written on it:

FLSUN STEP MOTOR
42BYGH718-B-28Q
LOT NO.210711

The total length of the motor is 47 mm.
