I have two CNC mills currently. A 3 axis mill and a 4 axis mill. The 3 axis mill did not come with a controller. So I set up a Raspberry Pi with a G-Code sender to make it work. It does a great job.
I am looking for input on flood vs mist cooling. I have a tray under each machine that can catch and allow coolant to flow do under the bench. The machines I have do NOT have shields for them. But that doesn't mean that they could not be fabricated.
Any pointers or places I can do some research or any inforamtion will be appreciated.
I like making chips, just not burnt ones.
