Whilst [Frank] mentions that this assembly has a weight and torque advantage over a NEMA 17 sized stepper motor, but we see no hard data on accuracy and repeatability which would be important for ...

An ESP32 runs the show in this build. Via a set of A4988 stepper motor drivers, it controls two NEMA 17 stepper motors which control the motion of the cutting and stripping blades via threaded rods.

Stepper motors generally are not available in frame sizes larger than NEMA 34, with most applications falling in NEMA 17 or NEMA 23 motor sizes.

Nanotec has created low-noise planetary gearboxes for brushless DC and stepper motors with NEMA 17 flanges (42mm, 1.7in). “With the GP42-N series,” according to the company, “the helical toothing ...
