The length will change depending on how many stacks, but so would the torque and other factors. Zax.

Hi Zax I had a look at that site you gave me and there is not a listing for the 57BYGH803 motor but there is for the 303 and even though it looks pretty much the same not sure, so I was wonddering if that would be suitable? Im no expert on the electrical aspects on these motors as you can tell by now. I heard there is a way to prevent these motors from stepping too far...This motor I have is used to raise and lower the bed on my laser engraving machine.
