I would think that the simplest solution would be to change the motors to tach feedback and then install either linear scales on the iron or install encoders on the ballscrews. I would think this would be the simplest way to handle it? ----- Original Message ----- From: "Stephen Wille Padnos" <spad...@sover.net> To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Sent: Saturday, March 20, 2010 11:02 AM Subject: Re: [Emc-users] G52 and Fanuc conversion to EMC > Paul Keeton wrote: >> Never mind on the Fanuc Motor and drive refit.
