CNC Machines – A Quick Introduction

CNC Machines - CNC Router - CNC Plasma

What is CNC? CNC Machines – A Quick Introduction, CNC stands for computer numerical control. It’s a term used whenever a computer handles machining operations and includes everything from 3D printers, CNC Router, CNC Plasma Machines to robotic arms. CNC began decades ago with the automation of industrial machinery and has since become much more accessible […]

How to set speed and acceleration values in PlanetCNC TNG software

How to set speed and acceleration values in PlanetCNC TNG software

One of the most important steps when setting up your machine in PlanetCNC TNG software is configuring machines’ max speed and acceleration values. With speed and acceleration values that are not suitable for one’s machine, the user risks lost steps(stepper motor) or increased torque(servo motor), damaged work-pieces, broken machine, and most important, lost time. To […]

Tool change settings in PlanetCNC TNG software

Tool change settings in PlanetCNC TNG software

Prior to following this tutorial we recommend that you perform tutorials below: How to measure tool offset with fixed tool sensor in PlanetCNC TNG software How to measure work position with the movable sensor in PlanetCNC TNG software   Tool change settings are located under File/Settings/Program Options/Tool Change:   Tool Change settings are divided into three […]

How to measure work position with movable sensor in PlanetCNC TNG software

How to measure work position with the movable sensor in PlanetCNC TNG software

This tutorial will explain how to correctly use the Work Position / Measure Height feature with a movable sensor using PlanetCNC TNG software and PlanetCNC motion controllers.   Movable Sensor A movable sensor is basically a switch that sends a signal to the motion controller corresponding input pin. The software will then calculate the Z-axis […]

How to measure tool offset with fixed tool sensor in PlanetCNC TNG software

How to measure tool offset with fixed tool sensor in PlanetCNC TNG software

This tutorial will explain how to correctly use the Tool Offset / Measure feature with a fixed tool sensor using PlanetCNC TNG software and PlanetCNC motion controllers.   Fixed tool sensor For a fixed tool sensor, we can use a dedicated tool measuring switch or, most basic solution, a standard microswitch fixed to a machine table. […]

How to set homing procedure in PlanetCNC TNG software

How to set homing procedure in PlanetCNC TNG software

This tutorial will explain how to correctly use the Machine/Home feature. The homing procedure will reference machine axes and set machine work area.   First, you would need to configure your machines step per unit values, motor & soft limits, and limit switch inputs of the controller: How to set step per unit values in […]

How to set motor & soft limits in PlanetCNC TNG software

How to set motor & soft limits in PlanetCNC TNG software

This tutorial will explain how to set the motor and soft limits of your machine. Soft limits (sometimes also program limits term is used) will stop machine motion when motor limit values of specific machine axis are achieved (without any limit switch activation). Soft limits will stop the machine in a soft stop fashion, meaning axis motors will use deceleration  – hence […]

How to configure limit switch inputs of controller in PlanetCNC TNG software

How to configure limit switch inputs of controller in PlanetCNC TNG software

Limit switches are used for reference (homing procedure) and as a safety feature. In order for that software to recognize limit switch activation and makes appropriate action, we need to configure limit switch inputs in settings: File/Settings/Motors/Limit Switches. The examples below will demonstrate the use of different limit switch wiring methods for the X-axis. All shown principles can […]

 How to set step per unit values in PlanetCNC TNG software

How to set step per unit values in PlanetCNC TNG software

This tutorial will explain how to correctly configure step per unit values of your machine.   Step per unit value (in further text SPU) defines how many step pulses controller needs to generate in order that machine axis moves for distance of one unit. Units can be in millimeters or in inches. SPU value depends on few […]
