Hi Peter, And now I can see the summing is done right with the input. You guys knew what it should be and I just could not connect the dots. Thanks to you and Andy for sticking with me. Now it all makes sense.
I just found this, don't know why it did not show in all my previous searches: <http://jmcolee.com/CNC/SD-1525.pdf> I thought the tach would go to j14 where nothing is plugged in. Sure enough the tach wire is hooked to the board, a manual is so helpful. What I thought was a strange differential driver voltage was a single ended drive and the tach. Yea, they ran the wire up through the Anilam board so it confused me for sure. Today the BIOS battery went dead so I have to enter the proper cylinder and sectors drive number to boot. Hopefully I won't have to boot the Anilam again, that I have all the info I need now to move forward. I'll post my work on the web as I move along. Thank you very much, Dan. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
