just got my new machine this week it is a Supermax ycm-40 with a Centroid controller (m400) i will be upgrading the mother board and software this month so it will have conversational input. I'm new at all this and have never run a CNC machine. I do have a Bridgeport that i have been using for almost three years and just wanted to be able to do more. Have seen good and bad about the Centroid on this forum. Any advice will be good in what direction to go and i just want to say hi to all of you.
