And I'm guessing that the Mach3 printer port test is the equivalent of the Linux latency test. (and yes, I do know the latency problem didn't just go away by installing XP and Mach3. Matter of fact, since I've gone back to a Microsoft product, it is probably gotten worse).
Pulse generation problems would normally show up in multiple axis, not just one. But if the emc latency test showed marginal, odd's are that MACH3 won't do as well.
Any chance the coupler set screw is slipping?
Phil, Still too many interests, too many projects, and not enough time!!!!!!!!
