Yes, 100% correct a chip is needed. He uses Microchip’s LAN9252 This is the most expensive part on the board. They cost about $13 each. I thought such chip were hard to acquire but no. ++ about master ++ I also just found linux master software. Goes with the demo posted to youtube. I looked at the demo hal file. It is very simple. He writes planer's output (x,y,z) directly to Ethercat device at the servo period. there is no feedback, just writes to the Ethernet. look here on GitHub for both the snapshot of MachineKit he used and the ethercat software. looks https://github.com/aschiffler <https://github.com/aschiffler> -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
