G-Code2GRBL is a tool for connecting a tablet and a GRBL CNC machine. It is an essential tool for everyone working with a CNC machine. This App provides a simple interface to send files, including G-Code files. It is a tool for everyone because it is very easy to use. You can use the app as a source for your G-Code files and send them to the machine. If you are a CNC machinator, you can use it to control your machine.
It is very easy to use. First, you have to install the App and the companion software called HC-06. If you are using a Bluetooth receiver, you have to connect it to your tablet. The App will detect the device and then you can use it as a source for your G-Code files. If you are using the serial port, you have to connect the App to your CNC machine. The source will be determined by the device.
