Nice. The first one must be a dithered image used with DotG or the like. The second one a very nice grayscale and the third seems like a poor attempt at grayscale

I see. Pretty neat. But afraid I will not be able to use it. My laser has a USB dongle which does the communication between the machine and PC. So can only use their supplied software. Which would accept Gcode file as input or images.

That's good to know Art. I have never used Auggie. Have had Gearotic since its first days, but never got to see what Auggie was all about.

Tweakie, I cannot understand the Gcode you attached. There doesn't seem to be any laser control commands, just G1 moves side to side. No G0's or anything.. either I am missing something in the way you control your laser, or it is the wring file.

Thanks. That was my guess too regrading the wavelength. It's not UV here, but just violet at 450nm.

I am using the software that came with the laser. The controller doesn't seem to work with any other sowftare. It either does photo or accepts Gcode. But the way it uses Gcode is not common to all others - on G1 moves the laser turns ON and on G0 it turns OFF. This is the only way to switch the laser on and off from within Gcode. I will look into the gcode you sent Tweakie and see if it I can adapt it.

Tried to adjust the laser out of focus slightly. Can't say that it helped to produce more shades of grey. If find that trying to engrave a photo on wood is inconsistent and since the wood is not uniform I usually see different tones for shades that had to be the same. The darker shades work better the lighter usually are not seen at all. Increasing power burns the dark spots too deep.

Hi Art,

That's an interesting suggestion. Thanks. I didn't think that way. Will experiment with this.

Hi Tweakie,

Just tried on some plywood and at least got something that looked like the original photo. But it's still far from the work you do. I am getting the feeling that the more denser the wood and the finer the surface, the better result you'll be getting.

Very nice photos you engrave there Tweakie!

I have a 15W Chinese laser diode machine (450nm), but can't engrave any photos on wood. The laser mainly curves the wood, but not burns it to different shades of gray. Only have ever tried soft wood (pine), could be that on harder wood it would work better, I don't know.

Interesting! Writing a postprocessore for one of the program out there, doesn't seem fun though

Thanks guys.

Jan, no - didn't use your program. I used PicEngrave  and the rotary engrave option.
