The laser variable feedrate replaces the Z with a F. The Feed Rate Change adds the Z depths and the F for variable feedrate at the end on each line of gcode.

If the Feed Rate Change feature was available, there would be an input for the feedrate percentage and a selection to add it or not. I don't see that in the screenshot.

Does the 3rd Axis letter change to a F when selected?

That is nice, but I am not familiar with UCCNC and won't be changing over from Mach3 to something that isn't proven in my opinion.

Is it possible to control the resolution of dithering? I am now able to get fair results, but would like higher resolution. I am trying to engrave an image on a small pendant so the image size is about 25x25mm (1"x1"), but after the image is scaled down to this size and I perform dithering, the dots I get are very coarse and the image looks poor. With a larger image the dots remain the same size, but considering the larger image size it looks fine.

Try increasing the DPI resolution in another image editor before opening it in the PEP editor to dither. Also experiment with the Atkinson dithering algorithm as it's adjustable.

Increasing the DPI using GIMP, but it affects the size of the image, so that I have to scale it again using PEP. Played with Atkinson but it doesn't give what I want.

I use Corel Photo Paint and it lets me increase the DPI without effecting the size. Good case of you get what you pay for;D
