Floating Tool Mount

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.

Oh, yeah that is great! I am adding that to the gallery right now, too cool.

That’s great! Can you post the STL to Thingiverse? I want to use a floating tool mount with a marker to make an eggbot (yes, it’ll need one more axis to rotate the egg).
