Title: Show me your grayscale!!!!
Post by: Betcmrekoapl on December 19, 2016, 03:15:41 PM
Is anyone doing anything in grayscale? any tips on setup? I currently have the a3 frame with the 2w ttl laser added on. Im running t2laser and loving the features. it takes sooooooo long to actually engrave any raster images that using trial and error to experiment in grayscale would take weeks! Maybe some of the veterans could share some tips and show off their work?????

Here are some greyscale images done on wood and slate with T2L.
I don't have the settings with me so I can't give you those but they should be here on the forum somewhere.

With a 5.5w module and T2 I'm doing 2000 at 0-255 and resolution 0.2 for engraving 13x10 cm photos on poplar ply. Looks good. (I don't have any at hand)
I guess you might go a bit slower then 2000 as your laser is weaker, but I guess not too much, as your focus point is smaller.

WOW that yoshi looks great! what material is the second one engraved on?

The second one is a 100mm slate coaster.  They can be found at michaels craft store for $3 for 4.  I did almost all my christmas presents on slate.  It turns out great.  There is a whole thread agastar and i wrote on the topic.

HAHA! I'm still alive aren't I? LOL.

I got extremely lucky with the settings. His laser uses coreldraw to control it and when I clicked on the engraving button, it was set at 400mm/sec and the power on the laser was set to 13 watts. The only thing I adjusted was the resolution from 2 to 3. I'm not familiar with Coreldraw but the way he explained it to me, it works the same as the resolution we use in T2L and a setting of 3 means more space between each laser pass.

I love that one you did with Dobby! That would be very fitting in my house

I also like the Dobby. Etched in wood. Now using it as the test pattern for slate coasters.

any luck yet or is the marijuana slowing you down?

Did you design that yourself or find it online (Dobby....not the marijuana)

I have been wasting time playing with gimp. Isolated Dobby and experimenting with adding text of different sizes, fonts, and effects. So far I prefer Currier New Bold, 36, no antialiasing, no hinting.

Smoke from etching card stock is powerful stuff. Can't wait for till I start etching Dobby on organic leaves.

Thanks!  My wife is huge into Harry Potter...actually cried when Dobby died. She is between jobs right now, so I think something like this in our house would be halarious.

Well, somehow I missed the replies on this thread, sorry about that guys.

Yeah, I still have all the files we used on the slate coasters. I'll grab them and post them here when I get home tonight.

The Dobby image was something my wife found online and gave to me to engrave. My skills are not that good lol.

Still, thanks for posting the png. I am looking forward to surprising my wife with a plaque like that.
