Shapeoko Proximity Switch Kit Standard

Added to your shopping cart

Ready to make the jump from mechanical switches to inductive switches? The proximity switch upgrade kit includes everything you need to replace your original homing switches on belt-drive X/Z and HDZ machines.

The Carbide 3D Proximity Switch Kit is a complete plug and play solution that replaces the mechanical switches on your Shapeoko 3.

Note: Only machines with a Carbide Motion PCB version 2.4d or higher are supported. Shapeokos purchased from us in Feb. 2017 and later likely have a supported Carbide Motion PCB. If you have an older machine, or you're not sure what board you have, get in touch with

Note: This does not work with the Shapeoko 4.

  • Inductive homing switches for X, Y, and Z (with adapter board)
  • Mounting Brackets
  • Hardware
  • Compatible with HDZ
    • The proximity switches work with HDZs purchased through Carbide 3D only.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

4 Electrical Prototyping

Skill Level: Experienced - You will need to consult a datasheet for calculations to determine a components output format, linearity, and do a little math to get what you need. You will be using a datasheet or schematic beyond basic pinouts.
