Grayscale

[keetonr]

Is there any software for my 3w 50x65 cm laser that supports grayscale?

Download my trial of T2Laser, move the jumper under the Nano chip (where the USB connects) if you have one to the 0.9 position and then install Grbl 1.1c firmware using T2Laser.

Can you be more detailed on the plastic jumper? Which piece on the board is that? I looked at your pdf file and I still dont understand which piece I am supposed to move.

Not all controller boards have the jumper. If yours does, it is typically located under the Arduino Nano CPU board. Note the orientation of the board before you unplug. Some Eleks boards have an extra 2 unused pins.

As already said, not all boards have it. If you load the Grbl 1.1c firmware (or 0.9g) and the laser is always on then you need to move the jumper. The other way to check is look and see what laser pin you have selected in Benbox, if it's 11 then you are already setup on >=0.9 but if it says 12 then you are on the older setting <=0.8.
