Today we’re troubleshooting why the Beelink computer cannot see the Centroid Ether1616 I/O board in my new CNC controller build. It turned out to be a really subtle (fun) issue. The system is running Centroid CNC12, with an Acorn and Ether1616 I/O Expander. And when we’re done, it will all be working.
This appears to be a bug in the Realtek GbE network hardware of the Beelink computer. But there’s an easy workaround.
