About this app

G-Code2GRBL

This App provides the interface between a tablet (10” preferred) and a GRBL CNC machine. The connection is using Bluetooth. The preferred receiver is a Bluetooth device called HC-06. More details about the connection is shown on the Help-Tab „Hardware Prerequisites” inside the App.

You can use raw G-Code commands as well as predefined buttons to control your CNC device. But the main feature is sending G-Code files to the GRBL controller.

GRBL Versions 0.9 and 1.1 are supported.

Some Features are:
- Buttons to move all Axis and setup zero positions etc.
- Support of Z-Axis Probing
- Sending G-Code files
- M06 Tool Change adapted to GRBL's M00 Pause command
- Observing the communication
- Store often used commands
- Arduino Sketch to configure the Bluetooth receiver
- Help Pages to setup the Bluetooth connection
- Speed Change during file transfer

Required Permissions:
- SD-Card read/write/delete
Read files to be send to the CNC machine
Write Setup files and the HC-06.ino Arduino Sketch
Delete - not used
- Access to the Network
Copy GCode files onto the device
- Admin Bluetooth Settings

Sometimes I get crash reports for older versions. Please do an update and check yourself if the error has already been corrected.
If you want to help me with the improvement of the app, please communicate problems and instructions for the reproduction of the error via email.

I can connect my android via USB cable or Bluetooth and use the control buttons in my grbl controller app to move the laser around and burn straight lines but I an looking for a mobile app that I can import a picture to and have the app do the work so I just push start and it burns the picture. Is there any such app that is very simple and can do all the necessary set-up or do I need to become a computer programmer to work the laser. This is more frustrating than I thought it would be trying to

this App isn't an all in one solution. This App is intended to setup a CNC machine and send machine specific G-Code.And the CNC must be controlled by the GRBL firmware. The interface to the machine is Bluetooth, respectively a HC-06 Bluetooth module. Didn't your laser engraver come with one or more apps doing the job you want? More help via Email

This is quite the app to have access to for using grbl. The interface is well thought out an accessing files on a network is easy. Bluetooth support works well. Easy app to recommend.

After a short period of difficulty, the developer has helped and everything IS now Ace. Very good app. I haven't found the emergency stop, perhaps an emergency stop button and return to would be size. I am an almost novice at cnc..
