I think the hole feature directly translates into drill instructions in compatible output formats. Where pocket just modifes the 3d shape, not that you couldn’t use a drill but it would need more software to spot the hole like shape and use a drill for it.
A Raspberry Pi 3 Model B
It’s connected to my 3d printer and runs octoprint allowing me to upload print jobs. and control the printer from my home network.
It serves up the Pi camera video stream.
It can also switch the printers light on and off.
No cluster setup.
