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.

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

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.

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.

T2 Engraving / Re: Running Multiple windows and Lasers
« on: April 21, 2018, 08:39:25 PM »
Hey guys. Just a question. Ordered a new A3 Pro today and was wondering if it is possible to run multiple lasers at the same time off the same laptop. Basically , can you open multiple windows of t2 and link them to different lasers to engraved at the same time?
Yup. I do it all the time. Just be sure you know which window is running which laser!

It is only on the lighter colored grey slate coasters. The darker black ones engrave with no issues or smells
Lighter grey ones?!?!?!

I tried another idea recently that I think is a nice effect.

1. Seal blank slate coasters
2. Engrave
3. Add water based coloured acrylic paint over the entire surface and leave for a couple of minutes - this soaks into the engraved areas only
4. Wipe off paint
5.Optional - coat with more sealer

Ok I tried this and failed.  I just saw why!!! I didnt seal them first.  Just eched then put on paint then tried to wipe off.... I thought that seemed wrong and the result was the paint was impossible to remove.  Read all the directions lol.  Seal, engrave, paint, wipe, seal.

The file is free online. There are services which you can pay to print it for you. Like 3dhubs or shapeways or print a thing.

you might want to check your wheel tension.  it can cause backlash too.  it looks like your middle one is better but it is still occurring.   https://youtu.be/ZzO9skEYqwY?t=55s

T2 Engraving / Re: DXF part disappear

Fusion is overkill but it is not like flying a b747.  It is complex if you intend to use it to its full extent but that can be said about almost all cad software.  Fusion is actually very easy to use to do a dimensionally acurate design in 2d or 3d.  If you arent using it I think your assessment of the software is extremely biased and uninformed. Your advice to keep it simple is sound.  If you have fusion making a design and then into a dxf is simple but it seems to not be saving appropriately... which many softwares also have problems doing.  This seems to be a problem with the file format itself.  No one has a problem reading a txt file or a doc file.  They are much more standard than our cad file types.  I have tried qcad librecad and nanocad and I dont like them.  That is probably because my first software was autocad and I am used to how autodesk designs their software.

Your .dxf file has no units of measurement set. I don't think that is causing your problem but it's the one thing 70% of users fail to set. So no matter what else is happening with your file, set your units of measurement!

Do you actually know how to do that in fusion 360 ralph? The document settings shows the units as MM.  When saving there is not an option to set the units.

Okay, this one was export from Fusion 360 and it still got the same problem.  Do you mind to upload yours for me to try?
How are you saving it? I right clicked on the sketch and clicked save as dxf.
