    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:

    WB-tst-on-12x12

    WB-Test-Crown

    WB-Logos

    WB-Warriors

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

    WB-TIST

    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).
