My machine is a home built one with 3 Axis x,y z with a Katsu Router.
I use it mainly for hardwoods like oak. i.e. this model is of Dr Who's Tardis and is only just over 3 inches tall and will be milled from one solid block.
My machine is running GRBL 1.1 on Arduino and is controlled by UGS on a windows 10 pc.
