A broken bit caused a lot of smoke and burnt wood recently…
But why not make use of it intentionally?

Looks so simple. Can‘t watch the video with sound, but I guess there might be instructions.
No instructions in this video.
Just an upside down 6mm endmill at max RPM and a light 0.1mm pass followed by a second one with 0.05mm to darken it a bit more.
Creates a lot of smoke - doing it inside may upset both fire alarms as well as significant others

Mine is used to those types of things on a continuous basis. Loud noises, odd smells , swearing at nothing, lights flickering in the house, the list is quite impressive

The fire alarms will get over it.

The significant others, not so much…

There’s a forum post somewhere around here about using Mt Dew to put out CNC fires. Don’t ask me how I know.

Would this count as burnishing?

A 600W router putting that energy into a dull endmill has a lot of power. This is actually a great example of why you should never leave your machine alone, while not being so fear mongery as the fire threads.

Hi,
“Never leave your machine alone” is a very very important lesson.
Starting a fire takes less than half a minute at the right conditions and I’m planning on making a video about this, too.
But this is something for spring when I can leave all windows open for a while to get rid of the smoke. At the moment it’s just too cold for this.
Funny enough intentionally burning wood with a dull tool should be relatively safe as there are no fine wood chippings created and the solid board won’t catch fire that easily on its own.

I had been thinking about this for a bit, but … What about the other room with a baby monitor and WIFI control. and giving a belts and suspenders treatment, a smoke alarm above the machine and wiring in a relay to power the router so that when you hit the BFRB in the software power cuts as well.
