This motor from E3D is for when you need extra power and motor mass is not an issue. Best used when you want a fast accelerating axis where the motor is static.
Also, note that the step angle for this motor is 1.8 degrees instead of 0.9 degrees on the rest of our range. If upgrading to a super whopper ensure that your firmware's steps/mm are adjusted accordingly (i.e. doubled).
Supplied with motor cable.
