how does it lock or brake? Normally a concentric nut will stop it from moving and flattening the fence against the rail on a normal fence.
Great question! The stepper motor itself is what locks Rip-it into place. Think of Rip-it as a single axis CNC. When the stepper motor isn’t turning, all of that power is holding the motor in place at a specific step. The motor is tied to the pinion gear at a 1:4 gear ratio giving the motor a locking force of over 100 lbs.
