I finally had some free time to fire up “Brigid” this Sunday!
Celtic knots with ravens and wolves seemed appropriate for the first prints from Brigid’s forge. (NOTE: I did not draw those knots. Art was found via google image searches.)
First up was the proofgrade draftboard. Beautiful - and surprisingly entertaining watching laser vaporize the draftboard.
Next up: Marble tiles. When I tried to scale up the prints and cut on the marble, the app kept crashing. I finally got the file to start, but scared myself when I mis-measured the marble tile at 3/8" depth… the printer head went through the motions of engraving but left nary a trace on the tiles. I was convinced I had killed her for that long 45 minutes.
Thanks to other community member posts, I also discovered the app was likely crashing because my files were too large. I sliced the ravens file into quarters, reconnected them in Inkscape, then ran that on proofgrade maple (5.5"x5.5"). Unfortunately, the reconnections looked smooth in Inkscape, but in the engraving, the intersections of the pieces were marked by darker, raised lines.
Final run of the evening was the original ravens knot file on a 4x4 marble tile. (4 passes, full power, full speed, 225 lines per inch).
There are a number of possibilities about why your file was too large… was it vectors or raster? The GF should be able to handle anything that is 4x4", I’m guessing that if it was a vector, it was just overly complicated, or if it was a raster, it was too large to begin with, and you could resample it down to a reasonable image size.
In any case, it looks great, and I think you can solve that overlap problem with a little work on the source files if you’re going to do it again.
Truly, it’s pretty subtle if you look at it directly overhead. But from a low angle, it’s neat. I may try additional passes on another tile, and I’d also like to play with adding a background color into the etching for contrast.
Tremendous thanks for the great suggestions! To answer your question, the file was vectors. I think you’re correct - it was simply too complex for the app to handle.
I am completely new to Inkscape, so there’s bound to be some lessons I learn the hard way. Thank goodness for the detailed online manual and introductory lessons!
I’ll likely circle back to the fixing the ravens file later this weekend. First free time with Brigid since round one 4 weeks ago!
