Hello,
I have a CNC taig desktop mill and I have two problems cutting up aluminium.
First is when I cut a slot a few mm deep the mill starts to squeal
What's causing it?
Second is I'm having trouble cutting one of the sides off a piece of T section. What's the best way?
I've tried putting it in a vice and either cutting a slot with an endmill, would it work better if I used a slitting saw?
