That looks very good. This inspired me to have a play with a bit of 19mm Bunnings pine that I had and found that with the above settings one pass at 3mm/sec will engrave to a depth of just under 4mm, which is very impressive.
A couple of things I noted, and these are Laserweb issues not Emblaser ones - firstly the laser raster option leaves a bit of a pixellated edge, albeit that you have to look pretty closely to see it. Wanting to get rid of this I took the same bitmap, put it into Inkscape and converted it to a path, then sent that BACK to laserweb and created 2 toolpaths, one with the laser fill option using the same above settings to do the engraving and then one set to laser cut but 50% power to clean up the edge. Comparing the two results the depth of cut is the same but the second one with the edge looks a lot neater - through a magnifying glass at least…
Here are some pics , apologies for the blurriness because these are pretty small, but the lefthand tail of the 'K" is obviously a bit more jagged in the top picture (laser raster) compared to the bottom one (laser fill and then laser cut)
.Secondly the raster option had the laser head trundling back and forth across the whole work area, turning the laser off where it didn’t need to do anything, whereas the laser fill option just travelled along the path that needed burning. I didn’t time the two to see the difference, I wish I had.
I’m interested in trying the same thing on some hardwoods I’ve got to see how it goes there, but I’m really loving the Emblaser 2,
The fine detail it can do is just amazing:
(and I love my my Emblaser 1 too, in case its reading this!)
