Interesting! I just now jumped into CNC milling with a mill that uses a 1994 dynapath delta 20 controller. I have the programming manuals but just getting started. I know about Parts and Smarts in Wisconsin and that dynapath in Detroit still "supports" the 10 and 20 but sure wished i could find someone in the Portland, Oregon area who can work on this controller and servos in case i run into problems. On this board somewhere i found a previous thread on Dynapath listing a guy in LA that used to work for dynapath but need to find someone closer. If you find someone in the Nothwest, please post that info. So far, everything is working but you never know.
