The uStepper Dual mount allows the uStepper to be mounted either magnetically or mechanically. The magnetic fixing means the uStepper can be attached to any size NEMA17 Stepper Motor.
If your application requires a more rugged mounting solution, then this is the answer. It will permanently fix the uStepper to your NEMA17 Stepper Motor. Please note the bolts only fit our 62oz NEMA17 Stepper Motor, different bolts would be required to mount to any other motor size.
