Hi @VetiTheYeti,
It sounds to me like you need a proper dust shoe, this should take care of the problem almost completely.
I’m intrigued, what exactly gets hot ?
If you don’t want to get a dust shoe for any reason, then you have the option to install guards of some kind on the sides at least, I did that on my machine for when I cut aluminium (which is a similar usecase: I have an air jet blowing chips away from the cut), they are made from aluminium corners and foam insulation material:
and do a great job of at least containing the mess inside the work area:
EDIT: original thread here
But really, for wood, a good dust shoe will do wonders for you.
