<p>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:</p>
<p>FLSUN STEP MOTOR<br/>
42BYGH718-B-28Q<br/>
LOT NO.210711</p>
<p>The total length of the motor is 47 mm.</p>

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.
