step 1 is to find your ideal greyscale setting for your laser and material.

Go to the help menu and try the greyscale under samples.  adjust your speeds and power until you have several shades of from nothing to black.  If all you have is white and black on the greyscale bar you wont be able to get a greyscale photo.  Try not to adjust a bunch of things at once.  do speed until you are satified.  Then work on power until you are satisfied.  If you change materials you will have to do this all over again.  different materials react differently to heat. for greyscale on stone I was using 0-180 for power and 1800 on speed.  Those setting will mean nothing to you working with a different power laser on a different material.

Good luck and happy testing.

Thanks for the info and the quick reply. I started with the different setting for the power 1000-600. 600 look good, so I started to try different resolution 255-64. I will plugging away it.
Thanks again for your help

ok i think your terms all all mixed up.  If you are using the firmware in t2 then the max power is 255.  600 and 1000 would both be over 255 so they would just be converted to 255.  My guess is what you are calling power is actually speed.  speeds of 1000 or 600 would show a diffrence.  What you are calling resolution is actually our power.  Resolution default is .1  This means 10 lines per mm.  a resolution of 64 would be 1 line every 64 mm. 

So what I think you actually mean is

power 64-255
speed 1000
resolution .1

Having your terms right will help you interpret the setting other people are using.  I post all my settings in the project posts that I do so I can use them again the next time.

Here is a video I put together.  The first part is how to enhance a picture for laser engraving.  The last part addresses how to set up t2.  You can start at 5:24 if you just want to see the greyscale setup I use in T2

Yes you are correct. Sorry for the confusion. as I stated I am new to this and  I do appreciate your help in using this software. I using the main panel and the laser controller panel and probably getting confusion on which one.

gotcha.  Thing to remember is the laser control panel setting are for manual operation.  They dont change your g code unless you select override power or override speed.  so make sure you go back out and regenerate you gcode when you want to make changes.

Nice video @nottingham82 - very helpful. One tip I'll add here since it wasn't mentioned on the video - I notice that the ply you're engraving on has a very distinct large grain pattern. The type of medium that is engraved will have a strong effect on the "resolution" aka detail of your picture. It was hard to make out the dimensions of your image from your attached screenshot since the numbers were so blurry, but I would suspect you would need to have a larger vs smaller engraved image since the ply grain is very coarse. If you engrave at a smaller size, a lot of detail will get lost in the actual grain of the wood.
