After doing some manual tests with a Harbor Freight wood burning tool in a mount I made, I anticipated some issues that might be helped by a mount that has some Z “float” - relying on the the tool weight to provide contact with the work surface, rather than driving it in with the motor.
Here’s the mount I came up with - it uses a miniature slide stage.

First tests done in 1/8" plywood:

My camera has some barrel distortion shooting close up - the squares are square, and the circles round.

After changing to a sharper tip, I added some ramp-in on the next test in an attempt to minimize the spot at the beginning of the paths. This test was done in 1/4" balsa wood. Note precision fixturing.
