Mach 3 looses steps like crazy when on the Program Run page and the axis are jogged.  When I go to the Diagnotic page and move around they are smooth and never miss a beat.  This is on a Taig mini-mill, by the way.   Any ideas?

Are they jogging, or moving at the same rate in run,jog, and diag.?

Whatever I set the jog rate to is what they travel.  If I set it for step then they step by the set inc. also.  If I set it for a .2 step the axis may loose 2 or 3 steps in that distance, but if I do the same on the Diagnostic page it steps perfect every time.

What version of Mach are you running?

What do you have for a computer?

I am using Mach3.  I primarily use a 2ghz Inspiron laptop with 1gig ram.  I have 4 other destops in the room and have tried them as well with the same results.  The diagnostic utility does show my signal is pretty dirty, but I don't understand why it would clean up and work great just by switching the page within Mach3?   

well there was an error in the LED class that could be giving you this trouble. Try the newest version and that could help.

Thanks
