As I recall, there was a specific comment that lathes were not yet supported. For now I think I'll leave it alone because even if it were supported there are so many things on my plate that I wouldn't be able to test it anyway. Unfair to put pressure on Charles or anyone to get something working

A circuit with a reasonable fast CPU, Ethernet and the FPGA for an arbitrary number of communication ports, UART, SPI, CAN would probably be the ideal device for a linuxcnc server. I read fast and can't figure out the CPU on this chip. On Sat, 14 Oct 2017 18:05:52 +0700 TJoseph Powderly wrote:

It has no CPU unless you build one from cells. There are soft cores available. This is an add on card like mesa without any pci or ethernet _yet_. On Oct 14, 2017 7:22 PM, "Nicklas SB Karlsson" wrote: > A circuit with a reasonable fast CPU, Ethernet and the FPGA for an > arbitrary number of comm

Hi Gene, When I developed the ELS I didn't have a CNC mill nor even an indexing chuck. For me the primary motivation was that I had just finished building the Gingery Lathe and hadn't built any of the other tools to make gears for thread cutting and certainly wasn't going to buy them. I also did
