This means the pin for the output of the PWM cannot be changed. The pulse width modulation (PWM) for speed control of a motor or power control of a laser, is generated via a special pin function (hardware PWM) inside the ATmega328 (the microcontroller of the Arduino Uno / nano) on pin 11 (PB3, OC2A). More information here: quick-guide-to-setting-up-your-machine-for-the-first-time The product of $10x and $11x must stay below 1800000 to avoid pin frequencies above 30 kHz.Į.g. Note: a too large number for $10x (steps/mm) and $11x (max. The main settings are $3, $10x, $11x (x=0,1 or 2 depending on axis) to get the stepper motors running in the correct direction. The screenshoot shows the initial settings after the installation of grbl. Check the grbl-Wiki for more information. Now the buttons inside the GUI are enabled and the stepper motors can be controlled.Īfter pressing "$$", grbl lists the stepper motor settings, which must be adapted for each machine. After successful connection, grbl sends a start-up message "Grbl 1.1h ". Start GRBL-Plotter and select the correct COM-port for the controller.

Taking all of the above into consideration, if you are looking for a simplistic and efficient utility that enables you to accurately control GRBL and TinyG CNC machines, with the possibility to add even more supported controllers, then Universal Gcode Sender is definitely worth your attention.To get your Arduino to control a plotter, following steps are needed: Windows USB driverĬonnect your Arduino with your PC, on windows 10 the needed USB driver will be installed automatically, if not: the cheap Arduino clones often uses a CH340 chip. Precisely control GRBL and TinyG CNC machines You should know that the utility enables you to remove components, truncate decimal precision to any configurable amount, convert arcs (G2 and G3) to line segments and even remove the whitespaces from your projects.Ī 3D Gcode visualizer, real-time machine feedback and control, built-in pendant that enables you to connect to UGS using your table or smartphone are also part of Universal Gcode Sender's feature list. The rest of the workspace is populated by a Console and a Command Table, as well as a section dedicated for precise parameter tuning. The main window puts on display the basic details about the Connection and the machine's overall state alongside with the three-dimensional machine work and general positions on the upper left corner. The application's user interface is simplistic which, automatically, makes the workflow quite straightforward. The main advantage of using Java is the fact that Universal Gcode Sender can run on other important desktop platforms such as OS X, Linux and even Raspberry Pi. Java-based utility for CNC controllersĬonsidering that Java is installed on your computer's system, the application can be quickly launched by just double clicking its specific icon. With its self-explanatory name, Universal Gcode Sender is a streamlined Java-based piece of software that makes it possible for you to control CNC controllers like GRBL and TinyG with the help of your computer. G-Code is a programming language used to send advanced commands and instructions to CNC (short for Computer Numerical Control) machines.
