T2 Engraving / Re: Engraving slate with T2

I actually like that look, especially given the image.

I'm just warning you guys, I'm going to "borrow" some of these and add to my facebook gallery (with credits of course).

The advantage of using T2Laser is you get support and regular updates (new features and stable performance).

Those "free" options often end up costing you more in time and frustration  ;)

I'm pretty sure it will work with one of the firmware options I have, but it may take some trial and error to find the correct one.

The Nano probably has some firmware on already so that will likely work with T2Laser (to move the motors etc.) but you won't get the best results until you use one of mine.

I like that, the negative works really well, more engraving but worth it.

What program are you using for the designs and was that a single print for the motor / bearing holder? Nice!

That's beautiful Starbrow, very crisp image and you did an excellent job centering it too. Well done!

Your grey scale results are impressive too, I'm going to have to get some of this slate... if you other guys haven't bought it all up already.

@nottingham82 That's impressive, I am really surprised the slate shows different levels as well as it does.

Just enabling CNC mode may fix it as there will be a delay as the Z axis moves (it doesn't know you don't have one). So a spindle delay may not be needed, just change the Z distance to increase the delay.

Yes, with my firmware 255 is ON so if you put a meter on the output you should get 12VDC immediately when turning on the manual laser control. The small delay you have may not be enough to see but obviously you are getting some.

Maybe that's my issue, I still use the 2.5W non-TTL laser although I have a 2W TTL and a 1.6W new "blue" TTL laser.

I haven't managed to get any grey scale from slate or other stone materials, so look forward to seeing what you've accomplished. I will have to step up my game  ;)

I would forget grey scale on slate, you want a black and white high contrast type image.

Trouble Shooting / Re: Error 37 - Language file corrupt
« on: August 21, 2017, 07:56:51 AM »
So you have the computer set to Danish but in T2Laser it is using English.

When did you start getting the error?

It means that line 37 is corrupted, but I don't know how that would happen.

I can send you the language file so you can replace it, I will get your email via PM and see if that fixes the problem.

Italian?

If so, you need to update and it will be fixed.

I will send you the code by PM.

General Discussion / Re: Thoughts on photo engraving - best methods?
« on: August 21, 2017, 04:38:12 AM »
It really depends on the material, but for a photo (grey scale) the best method is variable power with a TTL laser.

If the laser isn't TTL then using Velocity Mode will be the best grey scale option.

Dithering and halftoning use similar techniques, either a diffusion pattern of dots or different size dots to generate a pseudo grey scale image. There are many algorithms but after testing I settled on the Floyd–Steinberg method. It is well documented and fairly simple to achieve.

Dithering works best if the material doesn't burn to varying levels, but is better suited to larger sizes.

You can easily crop the border off in T2Laser.

If you convert to vector the test will be outlined and not filled (since vector requires the laser to follow the path of the object and not scan). You can add hatch fill to create pseudo filling but then you are almost back to where you started.

You can trace it in T2Laser to generate the vector paths or use Inkscape or similar to output as DXF.

That is the definition of raster engraving, it scans back and forth generation the image.

You can use Rapid Skip Blank to speed up the travel between sides but unless you eliminate the border and run it as a vector there's really no alternative.

The entire job as a vector may not be what you want either, but with hatch fill it may work and would be quicker.
