So after a hick up https://www.picengrave.com/forum/viewtopic.php?f=14&t=263&start=20 I started really using the software picengraver pro 5 with picsender.
After reading the documentation most of the basic settings where easaly made. I only have to get use to switching between laser and spindle mode in picsender.
I have been testing with this image.
First results. The first part is in the bottom left corner. Pretty black. Forgot to set the $$32 to 1, the laser mode ;(. The second part I tested is above the first one. I just took the picture, did not dither it. The settings I used where, GRBL PWM, Feed rate 3000 unit/min, Pixel Resolution 0.1524, Max PWM 255, left angle 45 degree. As you can see it is not completely okay. First of all you see a black line, Windows screensaver went on. Unfortunately my laptop could not handle it. Second you see the image is not completed. Windows went in to energy saving mode . Learning on the job.
After this I decided to stop this image. In my opinion it was to dark. So I tested my laser focus with the lines you see.
Again I loaded the photo and I dithered it with Floyd-Steinberg. I lasered it with the same settings, only my laser was better focussed. Also I lowered my feedrate to 2000. I thought the 3000 was a bit to much.

What is your opinion about the last picture? I still think it is a bit too dark.
