I've successfully installed EMC and have it running despite a severe latency problem (~900000). Surprisingly it does not seem to affect the results I get out of my gantry router but I would rather have things as they should be. I have installed EMC on 3 different computers and get similar results so now I am thinking of building a dedicated computer for the software. Can anyone suggest a motherboard and peripheral combination that will work reliably and hopefully be a low cost solution?
