GRBLDroid-USB

Pilot your CNC machine using the GRBL firmware and this android app.

You need an OTG USB cable in order to connect your android device with arduino.

Uses *.gcode files ONLY (ex: TEST.gcode)

Please read the online documentation :

1) GRBLDroid-USB will work only with GRBL 0.9 versions

2) GRBLDroid-USB supports simple and advanced file mode.

I have followed the official instructions from here :

https://github.com/grbl/grbl/wiki/Interfacing-with-Grbl

The simple mode is as described here :

Streaming Protocol: Simple Send-Response [Recommended for Grbl v0.9+]

And the advanced mode is as described here :

Streaming Protocol: Character-Counting [Recommended with Reservations]

3) GRBLDroid-USB checks if the commands are 80 lines long (including the last enter char)

4) It is recommended to purchase a dedicated tablet for this job with a DC IN 5V jack.

With this jack you can always recharge the tablet and at the same time it will stay connected on your CNC machine via micro USB OTG cable.

5)GRBLDroid-USB works for :

FTDI FT232R UART

FTDI FT231X

Arduino

Teensyduino

CP210x UART Bridge

Prolific PL2303

Qinheng CH340
