This tutorial series will describe how to use USB devices with PlanetCNC TNG software. 1. Introduction One of the most common requests from users is how to use external USB device for purpose of expanding TNG functionality. This could be either simple machine control using a gamepad or two way communication where device sends data, and TNG responds accordingly. Luckily, TNG offers a powerful set of USB functions that allow user to communicate with a USB device. Klasifikacija usb naprav? struktura in način pošiljanja podatkov? 2. USB functions: usb_list() - Displays all USB devices, connected ..read more

If connection test was successful, and you can see parameter values displayed in the output window, then we can continue with next step, which is controlling the spindle. In settings under File/Settings/User Interface/Commands/Spindle Command -> enable option Uses M-Code: Type M3 into the MDI window and hit Enter. Inverter should start the spindle at set spindle speed, and LED display should show RPM value(if display is in RPM mode).   Troubleshooting If inverter will not respond to any spindle gcode command , it indicates that something is not ok. Type into the MDI window the followi ..read more

This tutorial will describe the necessary steps for successful control of your HuanYang VFD using PlanetCNC TNG software. Before we start, I would really recommend reading tutorials related to serial communication, MODBUS and PlanetCNC TNG software. These tutorials explain the tools provided by PlanetCNC and how to use them in order to communicate with external equipment using serial communication(MODBUS). Serial communication(MODBUS relay board) with PlanetCNC TNG – Part 1 Serial communication(MODBUS relay board) with PlanetCNC TNG – Part 2 Serial communication(MODBUS relay board) with Planet ..read more

Holiday season is upon us, and with global warming being more and more aggressive, we cannot rely on much snow during the holidays. This leaves us with no other choice than to make snowflakes ourselves – using paper and CNC laser cutter. Luckily, PlanetCNC TNG software program feature Image Import  comes in great help, so scissors will not be necessery. Image Import offers all necessary tools to import and process an image file in order to generate suitable gcode for our CNC machining application (laser cutting). Obtain image In your web browser search for “Snowflake silhouette”. Choose t ..read more

In this part, we will use and configure Expr.txt file so that we will be able to control relay board via serial communication using Modbus protocol. Expression buffer and serial functions described in first two parts will be used in order to achieve this.   Modbus supports communication to and from multiple devices connected to the same wire of serial communication line. In this tutorial we will use MODBUS RTU frame format. Modbus “frame” consists of an Application Data Unit (ADU), which encapsulates a Protocol Data Unit (PDU): ADU = Address + PDU + Error check PDU = Function code + Data ..read more

Last part of this tutorial series will describe how to properly design the expression code for Modbus serial communication. In previous part we made two expression functions. One was responsible for turning relay ON the other one for turning it OFF. Our main concern was just to make it work, to see that relay clicks and that was it. Now we will try to do it the right way, using an efficient, structured and optimized code design. Create dedicated expression file In root folder of profile folder create new text file. Use descriptive name for better  file transparency and organization. I use ..read more

We will continue with expression functions used for serial communication. In first part we described buffer expression functions, which are used to prepare the data for serial communication. Now we will describe serial expression functions that are responsible for actually sending the data. serial_list() - Displays all available COM ports of computer. serial_info(port) - Displays additional info of COM port of computer port - COM port name. Use string type ; e.g. "COM3" serial_open(port,baudrate,bits,parity,stopbits,flowcontrol) - Opens serial COM port channel and sets serial communic ..read more
