Printed a photo on my laser printer, decoupage’d it to 3mm plywood with Mod Podge, then cut it with a puzzle pattern, 2 passes at 20mm/sec ~10mA to try to minimize burning… except somehow I forgot to switch on air assist, so there was some flame!
I had protective tape on it, though, so not much damage to the image. The image did peel up a little in a couple places (shown here), so I Mod Podge’d em back down, not sure how durable it will be.
Durability test will be: give it to my 2-year-old, who loves puzzles.
Air assist really helps keeping the the charring down. I changed both of my moshidraw boards over to a MKS 2560 (Arduino 2560/RAMPS 1.4). I put a 10x15mm drag chain with a silicon hose to a 3d printed air nozzle. Using a Select Comfort air bed pump. I’ve also modded the Turnkey Laser Exporter Inkscape extension to also handle repeat=x in the layer names. So I have vector and raster cutting and engraving.
That looks really great! What if you cut from the other side? Make the first pass kind of heavy, then when you are about to cut through, lower the power so you dont char the paper.
@Tev_Kaber It turned out nice. The cut being not as deep on the lower right could be alignment, but could also be the distance between the head & the cutting area is not level in that corner.
A great site with a lot of pattern generators for boxes and things. UI is a little clunky but functional. It’s €13 to enable download as SVG, but well worth the price.
