GRBL Settings

• sending grbl commands via serial terminal to modify settings

Warning

When starting with a controller in factory settings the pre-compiled grbl library is not calibrated for the plotters dimensions and step-motors. Sending move commands altough necessary to test the settings may dammage the machine. Proceed with care !

1. Open the Arduino IDE, choose the correct port and board type in Tools -> Board: / Port.

2. Launch the serial terminal: Tools -> Serial Monitor.

3. Start sending commands in order to change the settings.

Example

The command $120=2000 will change the x-motor acceleration to 2000 mm/sec^2.

Reset
