I'm new to Grbl Controller and trying to learn how to use it. I have a very small CND hobbie machine. Is there some program that you can use with Grbl to play around and learn how to use it?
The software can't be used in demo mode. I've visited the official website and read about it, but there was nothing mentioned about demo mode which means that you can't use the application virtually without the proper machine attached to a PC port.
You can read more about it on the following page: http://zapmaker.org/projects/grbl-controller-3-0/
There is also a manual on the page. Click it and make sure that you have a PDF reader installed on your PC.
