• This kit provides all the parts to drive the spindle with a stepper motor.
• This kit is not able to synchronize any other movement.
• A rotary switch is used to control the spindle speed and direction.
• The kit's stepper motor is attached to a bracket which gets installed in the lathe's headstock.
• The kit's electronic components are in a separate box, with the power supply (usually) installed under the lathe's bed.

• The kit includes everything needed to drive:
• the spindle with a stepper motor,
• a stepper motor for movement along the Z axis¹,
• a stepper motor for movement along the X axis¹, and
• a stepper motor for movement along the B axis¹,
• It uses a touch screen to control the activity².
• It also allows for using limit switches to stop movement when the desired cut has been achieved.
• The kit's spindle stepper motor is attached to a bracket which gets installed in the lathe's headstock.
• It comes as a case which fits neatly below (or beside) the lathe's bed.


• The curvilinear slide will attach to this controls kit.
• The spherical slide will attach to this controls kit.

• Electronics are available two ways:
1. An assembled kit with the Pololu already pre-programmed and wired into place.
   (You will need to place the power supply in the lathe's bed, and attach the power switch)


2. A kit you can assemble yourself.
   This requires strong capabilities to assemble, program and test electronics, following the manual we have available.

• Electronics are available two ways:
1. An assembled kit with everything ready to go. Just plug it in and turn it on.


2. A kit of the hard to source parts which you can assemble yourself. This allows for lower start-up cost as you can add the stepper motor drivers as you have the need.
   This requires strong capabilities to assemble, program and test electronics, following the manual we have available.

• This option is significantly lower in cost (as there are many fewer parts), and is also much simpler to build.


• It is based on the Pololu Tic 36v4 and is designed to drive the spindle with a stepper motor.

• This option gives a tremendous increase in capabilities, but is also more expensive and complicated to build.


• This system is based on:
• Teensy microcontroller,
• Nextion touch screen display, and
• StepperOnline DM542T stepper motor drivers which are designed to handle plenty of current, allowing for selection from a good range of stepper motors.
