Greyscale for co2 laser 40 watt

[Squid]

Yes but not really recommended.

GrayScale Engraving

SKR 1.3 32bit 100mhz Controller. I don’t want to judge it too soon and before i will have a PC 1m away with a good USB cable. so far i am very happy. This is an image i just downloaded from the internet and without changing any settings from my grayscale calibration image, this is what I’m getting (On a gray 2mm EskaBoard): [ice_screenshot_20191117-205505] [IMG_20191117_210359] [IMG_20191117_211103] I am very pleased.
