But from the rumors I hear, newer versions are much more difficult to use. I've noted also that PMDX is noticeably absent from this list, and consequently long removed from my list of who to buy stuff from. Jon and Peter SUPPORT their stuff, so the list is both short and a no brainer these days. FWIW, that old control should still work, and while it was doing a 200 watt motor, the pass transistor has been replaced with a much heavier device and should not have a problem with a 400 watt motor. Very stiff speed control, I had to add an ammeter to see when I was about to blow a fuse. Somebody should make me a $50 offer as I'll never use it again. > > > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users
