Half tone picture

I wanting to engrave a halftone photo for a Christmas present.

What is a good software for making gcode from a photo.

I plan on doing this on glass.

Inkscape keeps giving me errors on the gcode.

any suggestions. Not looking to pay a tone of money for any software.

Some software I have looked at makes the photo look really bad and not like a half tone.

I think you can still download halftoner, haven’t tried using the gcode it generates on marlin, but you can generate a dxf file from it.
