I have gotten pretty far with my 8020 skate bearing design and it works quite well. The travel being X30/Y20/Z5 inches this is a little large for my desk, I want to use this larger one to make a dedicated PCB router, with travel being about X12/Y12/Z1 inches.
I'm going to use 1/2" aluminum for this smaller one and I'm just looking for ideas on styles and types.
Thanks for the help.
