I have some Pi and BBB boards that I use for robotics projects. I use them because they are physically small and can run on battery power. But do people need that for a machine tool? Are people building portable battery-powered CNC milling machines? If the machine is very heavy and requires AC mains power then why not make life easy for yourself and use a big old PC.
Seriously, you can buy a good used PC that will run circles around a “BBB” for not much money. Add a Measa FPGA card and you are good to go. https://www.newegg.com/p/N82E16883461141?Item=9SIABX7JBU8332 Refurbished: DELL Desktop OptiPlex 3040 SFF Intel Core i5 6th Gen 6500 (3.20GHz) 16 GB DDR4 256 GB SSD DVD Intel HD Graphics 530 Windows 10 Pro Grade A newegg.com > On Aug 4, 2023, at 9:44 AM, John Dammeyer <jo...@autoartisans.com> wrote: > > I'm curious.
