16 X 2 I2C lcd with GRBL

Projects General Guidance

Hi,

I'm creating a cnc machine and would like to know if I can use a 16 X 2 I2C lcd with GRBL and cnc shield v3?

Any help will be appreciated.

No. GRBL does not include support for any display. You should probably put the display on your GCode sender.

Sorry about the delay

I am using Universal G-code sender. How can I add the display?

4

Modify "Universal G-code sender" to display what you want on whatever display you want.

I tried but don't know how to modify it to use my 16 X 2 I2c lcd screen.

Any tutorials or suggestions?

I also have LaserGRBL

Sorry. I have no idea.

What was it that you hoped to display on your 16x2 LCD?

8

X Y Z positions and current state

Can't you see those on the Universal G-code sender display?

If you want to see the data on a little LCD you may be able to get the data from the serial messages going from GRBL to the G-code Sender. Get a second Arduino and connect the LCD to it. Connect the RX pin of the second Arduino to the TX pin of the Arduino running GRBL. Then you just have to interpret the data stream.

read the FAQ of GRBL.
They explain why it is far more complicated to add a display to that code. And they give a proposal and two links.
