Perfect X-Axis replacement.
Purchased to replace the X-Axis stepper on my K40 machine. It's way overkill for the machine, but it's a nice component that can later be used if I move to a larger stage. It's being driven by a Gecko Drive G201X (running at 24 volts) and an AWC708C Plus. Very inexpensive upgrade. Motor fits fine and has plenty of room since there is nothing below it. It is a bit larger than the factory stepper and runs much cooler. I like the JST connector on the motor housing much more than permanent leads.

Great motor, has held up to heavy usage well
I use this as the motor for my X-axis on my DIY Buildlog2.0 laser machine. It gets loaded pretty heavily because I scaled the machine up to a 24x32 cutting bed and my travel head is fairly heavy. We do a lot of full bed size engravings and this motor gets a ton of use. I have it microstepping at 1/16 and it has worked extremely well for engraving fine details. Machine has several thousand hours on it and is still holding up well with no issues to date.
