You've done it all- high voltage stepper drivers, upgraded PSU for your motors, AWD gantry… where do you go from here? Kraken Motors, that's where! These extreme performance stepper motors are designed for perfomance, both with high torque and a high temperature rating. Thet even come with a built-in thermistor to monitor temperature.
These are available in 37 and 55mm shaft lengths depending on your needs; the 37mm version can be had with a D-cut shaft for light duty applications or a round shaft that allow for a bearing retainer at the end of the shaft for high torque stability.
And if that all wasn't enough, they come in their own plastic case!
