PNaedele,
I'd call quickly... Dyna itself is kind of kaput, I believe. They have no presence in San Jose at all, and I don't think they have any manufacturing elsewhere either. Although their website is 'up', I think it is being serviced by an ex-employee that has branched out on his own. The big question, however, is how long he will be providing that service. It could be a long time or it could be next week. I believe he has Dyna's old phone number, though, so you can try calling him. I'm told he is quite nice and very helpful.

bkobernus:
Thank you for posting that writeup and information "packet". I am hoping to pickup a 4400M in the next few weeks. One thing I noted on it, however, was that its switch panel looks different than others. I've got a photo somewhere that I can send, but between that and the fact that the machine has a 4th axis, it makes me wonder if the logic ladder might not be different (which I assume is the M3 parameter list). This, then, brings me to a different question entirely....

Do you know how to *download* all of the parameters currently in a machine so that you can back them up? Whoever generated that M3 parameter file probably has that information. I think the best solution for me would be to download the file for safekeeping just to be sure there aren't different flavors of M3 based DM4400M mills out there.
