Here is some great information about interfacing an LCD display to an Arduino running GRBL
You can also interface it to an excel spreadsheet with some additional electronics and display more info. It is a very interesting concept and great for people running stand alone options.
From the Shapeoko forum there is now an update for GRBL 1.1
hello grbl’s fans!
GRBL11universalDRO for GRBL 1.1 is available for download. http://www.shapeoko.com/wiki/index.php/LCD_on_GRBL#Full_version_GRBL_1.1
It was harder than expected :o
The new program will automatically recognize if the status data are GRBL <= 0.9 (U09) or GRBL> = 1.1 (S11)
In summary, before the state line was always the same, with $10=7 we had everything we needed.
With GRBL 1.1, there are only 2 options: $10=1 Mpos $10=2 MWPOS and some other status values, you have to choose and the received data are dynamic.
Have a look to the Arduino’s header programm and 2 GRBL documents Getting Started https://github.com/gnea/grbl/blob/edge/doc/markdown/settings.md
Grbl Interface Basics https://github.com/gnea/grbl/blob/edge/doc/markdown/interface.md for more details.
if you have any problem …
Has anyone kept the files and wiring diagrams for GRBL11universalDRO?
I want to use only an LCD with GRBL to view machine and work position.
