I've got two bands wrapped around the body of the router cut out of a bicycle inner tube. They help mate up the muffler clamps to the router body. I was expecting to drill and tap a hole into the router for a screw through the base plate, but with the rubber straps everything is very firm and tight.
Today I spent some time "cutting air" to make sure the tool would run properly before I put a bit in. I had to invert the Z and Y axes in the setup I was using as it turned out. Then I tested twice more, once again with no bit or wood, then again with a bit and wood in the machine, but the Z axis set high enough the bit of the router wouldn't quite reach the wood.
Everything looked good, so I made my first cut:
The material is some plywood I recovered from an old failed project. As you can see, it wasn't mounted completely flat. The top piece is held by some screws that hold it from underneath.
The G-Code was a raster pattern generated by an image-to-gcode converter that comes with the EMC2 software I'm using. That's why the bottoms of the letters look kinda scrappy, if they'd been cut continuously rather than raster-cut, they'd probably look a lot better.
The bit I used is a 1/2" 90 degree bit, I don't have any really nice bits yet. Now that I've got the machine actually cutting things out, I can work on refinements.
The depth of cut is 1/8".
Now I'm looking forward to getting some better bits, getting my CAM software in order, and so on.
Edit:
Had one more go with what I've got on hand this afternoon. It's a little more ambitious. Here you go:
