One thing to note is that, while you can indeed put drill bits of the correct diameter into your spindle, you need to make sure they are the correct length (“screw machine” I think it’s called).
I stuck a regular (jobber) length bit into mine, and when it tried to measure it, the bit was so long it crashed at full rapids into the probe. Made a loud noise and could have been very very bad, but luckily I was watching it and hit the e-stop before any damage could occur.
Also, watching the nomad drill holes can be absolutely maddening. It pecks into a hole, moves to the next, pecks, moves, etc, then goes back to the first and does it again. Wildly inefficient! It’s worth it to try to work out how to make MeshCAM give you sensible drilling g-code. Or get it elsewhere…
