I was thinking a dp83848 and UDP packets, like hm2_eth. @andy That video is where I got the initial idea using the IRAMX :D the first test was also with an Arduino, quickly realising that is is way to slow. my previous design was based on the IRFP260N > > At first I should get it up and running for two EDM machines.
