I bought a "Three-axis Engraving Machine" as a kit and I mounted it.
I uploaded grbl 1.0. The machine did not work at all. Regarding other comments, it seems not to be the right soft.
I then uploaded grbl 0.9 i. Now the card communicates with the machine : it sends commands, but absolutely nothing is moving.
A red light is on, on the card, everything is connected as it has to be connected.
I heard about the use of grbl 0.9c, which could be the right soft, but I cannot find it.
Please HELP !
