Trying to create a box with a sliding top. How do I create the slot for the top to slide in. Using PG .125. I tried manual setting on 50% power, but not sure if this is the right way to go. Trying to make the slot about 1/2 way through.
Engraving slots can be done but you’ll want to clean out the engrave - it tends to collect char and resin. (I have a little 3 mm chisel that works great for scraping.) Make the channel wider than the wood it’s receiving by at least 0.1 mm.
It’s really better though if you can to build a double walled box. It’s actually easier to work with, and you can cover up any unattractive finger joints.
I engraved a channel at 600/80 w/2 passes when using this plywood. I then cut a wood strip that I glued just above the channel for added strength. I cleaned the char by putting a little piece of sandpaper around scrap wood and running it through the channel. I ran a bar of soap through it for lubrication.
