NEMA17 ACME Lead Screw Linear Actuator


This ACME Lead screw driven linear actuator uses standard v-slot parts to create a very simple but powerful lead screw driven linear actuator. The linear actuator can be used for a wide range of applications, a standard-out example is the z-axis on a CNC machine, a similar set-up is used on our very own OX. By using the v-slot system, this linear actuator takes advantage of the smooth and precise v-groove to create super accurate linear motion.

Because this kit uses all standard v-slot parts it can be easily combined with more of these actuators, other types, or a design of your own to quickly build a functional machine.

Linear Actuator Gantry

We have a range of options available for this linear actuator, it is available in profiles of 20x60mm/20x40mm & 20x80mm. With standard lengths of 250/500 & 1000mm. If you need it to a precise size, other than the standard lengths, for an additional cost, our cutting service is available.

In addition to the rail options, we also have the option between 4 or 6 solid v delrin wheels, this allows you to beef up the gantry to your needs.

The maximum travel distance of the gantry is 100mm less than the extrusion length. For instance the 1000mm linear actuator has a maximum travel of 900mm.

Motor Options

For the motor there are multiple of options available. The first option is to have the linear actuator without a stepper motor, if you choose this option the hardware to mount the motor, and motion parts are still provided.

The second option is a stepper motor included. Stepper motors ideally need to be run from a controller with a stepper driver, the controller is not included with this option.

The final option is a stepper motor with a uStepper controller. The uStepper is an ultra compact stepper motor controller board, it is Arduino compatible with a built in stepper driver, it can be mounted directly on to the back of the stepper motor. In addition to this it also has a 12bit rotary encoder, this allows absolute position tracking of the motor shaft making missed stepped detection possible. The uStepper also has a built in temperature sensor next to the stepper driver, allowing for continuous temperature monitoring.

The uStepper needs to be programmed through the Arduino IDE to carry out the operations you require. To simplify this an Arduino library is available for uStepper which provides functions for all the main features.

The EGO Shield for the uStepper, is a 4 push button integrated OLED Screen shield for the uStepper. This allows basic control of the actuator without progamming knowledge. See related products below to find out more.

The uStepper has a max current output of 2A, therefore it can only be used with our 175oz 2.0A NEMA23 Stepper motor.

Minimal tools are needed, 4/2.5/1.5mm allen keys, 8mm Spanner, and a Screwdriver.

This is a very simple kit to build. Mark Carew, of Openbuilds, has made an excellent instruction video showing you how to build this linear actuator. This video can be found in the tab named “Instructions” directly under the thumbnail pictures above.

What You Will Be Getting

Everything to make a ACME Lead screw driven linear actuator, powered by a NEMA17 Stepper motor, as to Mark Carew's specification, with the options chosen above. A NEMA17 stepper motor is an optional addition, if you choose not to have a NEMA17 stepper motor, you will still get the mounting and motion hardware.
