Pololu Tic
Overview
Pololu Tic 36v4
The Pololu Tic 36v4 is an all-inclusive, very inexpensive, and simple way to get started with using stepper motors on a rose engine. Whilst it can only work with one stepper motor, it is a great way to move from hand-cranking the spindle to having the spindle driven by a motor.
As noted elsewhere, a stepper motor provides a nice way to drive the spindle at very low speeds and not lose torque. The Pololu Tic 36v4 makes the controls on this stepper motor match those seen on a traditional, variable speed lathe:
- Start/Stop
- Spindle Speed
- Spindle Direction
The implementation of this is quite simple, only requiring:
- Pololu Tic 36v4 stepper motor controller
- A way to control the speed. Usually a rotary encoder is used.
- 24 VDC power supply
Notes on making one
The documentation for building such a system, along with the components required is on the MDF Rose Engine Library. The document is on the 2nd shelf, and it titled Control System for Spindle Stepper Motor.
