Planet CNC USB Controller 24: A Review of Features and Performance
If you are looking for a reliable and versatile CNC controller for your hobby or professional projects, you might want to consider the Planet CNC USB Controller 24. This is a 4-axis controller that can work with stepper and servo motors, and has a USB connection for easy setup and communication with your computer. In this article, we will review some of the features and performance of this controller, and how it compares to other similar products on the market.
Features of Planet CNC USB Controller 24
The Planet CNC USB Controller 24 has a number of features that make it suitable for various CNC applications, such as milling, turning, plasma cutting, laser cutting, foam cutting, 3D printing, and more. Some of these features are:
3 digital outputs on board, which can be used to control spindle, coolant, mist, or other devices.
3 PWM capable outputs with selectable frequency (10Hz to 500kHz), which can be used to control spindle speed, laser power, or other devices.
3 outputs with support for RC servo motors, which can be used to control rotary axes, tool changers, or other devices.
Jogging keyboard support with speed potentiometer, shift, step and spindle sync feature, which allows you to manually control the machine movement and speed.
4 limit switch inputs, which can be used to set the machine boundaries and prevent crashes.
4 digital inputs on board, filtered and protected, which can be used to read signals from probes, sensors, buttons, or other devices.
Spindle encoder and index signal support for spindle synchronization, which allows you to perform rigid tapping or threading operations.
Control external devices with I2C and UART protocol, which allows you to expand the functionality of the controller with additional modules or devices.
Performance of Planet CNC USB Controller 24
The Planet CNC USB Controller 24 has a high performance and accuracy level, thanks to its advanced hardware and software design. Some of the performance aspects are:
110 kHz step frequency, 25 us pulse width, 50% duty cycle at higher frequencies, which ensures smooth and precise motion control.
USB connection with high-speed data transfer and low latency, which ensures fast and reliable communication with your computer.
PlanetCNC TNG software support, which is a powerful and user-friendly software that allows you to create and run your CNC programs. The software supports various file formats (G-code, DXF, PLT/HPGL, SVG, Gerber, NC Drill), has a 3D program visualization feature, supports various transformations (shift, scale, rotate, mirror), has a manual data input (MDI) feature for quick commands execution. The software also has a Python importer for advanced programs creation.
Comparison with Other CNC Controllers
The Planet CNC USB Controller 24 is one of the best options on the market for CNC controllers. It has a competitive price of 145.18 â (DDV vklj.)[^3^], which is lower than some other similar products. It also has a high quality and durability level. It is assembled tested and ready to use[^3^]. It also comes with a user manual[^3^] that explains how to install and use the controller. The controller requires a license[^3^], which can be purchased from the Planet CNC website[^1^]. Without a license it is limited to 25 moves[^3^].
Some of the other popular CNC controllers on the market are:
Mach3/Mach4: These are software-based controllers that run on your computer and communicate with your machine via a parallel port or an external motion controller. They have a large user base and support community. They also have many features and plugins available. However they have some drawbacks such as compatibility issues with newer operating systems (Mach3), higher cost (Mach4), dependency on your computer performance (both), and limited support for newer hardware (both).
GRBL: This is an open-source firmware that runs on Arduino-based boards and communicates with 061ffe29dd
