Was there not a saying "Nobody appreciates a genius"  ;)

Attached is an image with a "shingles" on the roof and a thin vertical line. To get the lines on the roof crisp I lightened up the BLACK on the shed and people. Etched slow at 0.1mm resolution. Not the direction you wanted!

In the end the only thing I liked was the thine vertical white line. Perhaps a similar line where the roof meets the side wall.

Thanks George,
I did have a go today and burnt 2 on opposite sides of the same mat. I used the default feeds and speeds on one and lowered the speed to 800 on the other. Pic_1 was the default and shows the white line and Pic_2 was etched at 800 and shows an embossed 'drain pipe' that is very cute. I will see what the committee think whenever we are allowed to meet again.
I also did another double sided mat with a mandala bunny, Pic_3 shows the result from sitting on the wire frame and is quite black and crisp, Pic_4 is the result after raising the mat 3mm and is a bit brown and not as crisp.
It was rather a good day today so I got a bit more sun time than shed time.

take care
Don W
PS I am going to try and etch a picture tomorrow.

I have 2 pictures I would like to try and had a look at them today. I loaded them into T2 and both files were quite big, in fact I did one at 0.1 resolution and the programme asked me if I wanted to do that ?? Is there a simple way to etch these ??
Any help on how to start this is welcome.

How large are you planning to engrave them?

Use grey scale mode, set the resolution to match the laser spot size (typically 0.2 is a good place to start). Set laser max to 255 or 1000 depending on your firmware parameter and adjust feed rate for the darkness required.

That's really all there is to it, T2Laser will analyze the image and in this case deterine photo mode (anti-aliased output) is best and generate the appropriate G-code.

Just say no when it asks about displaying the large G-code, as there's no need to see what it's going to output. It will use less memory and be faster.

Thanks Zax,
I will start here this morning and see what I can do.
I'm back. I tried the pics today and this is what I got on Birch laserply. Not sure if this is the best that can be done. I did try various speeds and found that the couple was best @850 mm/min and the group was best at 800. Maybe I could tweak somewhere else.
