Pololu Tic controller for the spindle stepper motor
If you are getting started, the best way to control the spindle's stepper motor is to use a Pololu Tic.
This little board (1.5" x 1.05" x 0.47") does a great job of providing a consistent speed for the spindle, enabling some great work. It provides a way to drive the spindle at a variable speed: 0.01 to 6.7 rpm. It is also a very cost effective option.
This kit is a great option for retrofitting an original MDF Rose Engine Lathe to use a stepper motor for driving the spindle.

The Spindle-Only Stepper Motor Control Kit we supply provides:
- a stepper motor
- stepper motor mounting bracket
- both pulleys
- drive belt
- all the electronics
|
If you would rather build it yourself, you can follow the directions in the blue book below. There are a few parts you will need to fabricate, and those are in the book noted above which shows drawings for the machined parts.

Teensy 3.5 microcontroller
The Pololu Tic is a great way to start, but if you want to enable significantly more capabilities, we have a second option based on the Teensy 3.5 microcontroller.
The controller based on a Teensy allows for synchronizing the motion of up to 5 stepper motors. This may seem excessive, but consider this very typical scenario were we use stepper motors for:
- Spindle drive
- Separate drive for the rosette (i.e., for a Rosette Phaser / Multiplier)
- Drive for a Curvilinear Slide
Some user functions enabled with this system include:
- Indexing (to tenths of degrees or portions of a circle)
- Thread cutting (with infinite thread options)
- Reciprocation
- Simulation of a geometric slide for rose functions
- Rosette phasing and multiplication
This kit is also a great option for retrofitting an original MDF Rose Engine Lathe to use a stepper motor for driving the spindle.

The Multiple Stepper Motor Control Kit we supply provides:
- a stepper motor
- stepper motor mounting bracket
- both pulleys
- drive belt
- all the electronics
- the necessary 3D-printed parts
- boxes to house the various pieces
We also offer an upgrade option, enabling you to move from the Pololu Tic system to this one.

If you would rather build it yourself, you can follow the directions in the brown books below. There are a few parts you will need to fabricate, and those are in the book noted above which shows drawings for the machined parts.
There are also some parts which need to be 3D printed, and the black book below outlines those and provides the files needed.
These are the manuals for building the control system which can drive multiple stepper motors simultaneously. Click on the respective part of the image to open that book
