Very late to this discussion. I had this problem about a month back, with an incredible amount of frustration.
In the end I found that on my G540 I had to invert the stepgen output. When inverted, no problems, when noninverted - one axis only would slowly slip regardless of step timings. I'm stuffed if I know _why_ inverting the step output would affect the drives behaviour to this degree - but if all else fails... -----Original Message----- From: John Alexander Stewart [mailto:ivatt...@gmail.com] Sent: 10 August 2014 22:21 To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] G540, 5i25, missing steps, once again.

I think I'll set everything up with even more time, and call it a day (or, 4 weekend days, to tell you how long I've been looking at this) Thanks all! ---------------------------------------------------------------------------- -- _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
