Hi all,once again im back on the bridgeport interact 1 mk11 y axis gross position error,I had a bit of a poke around like gus suggested on the tuning of the lag side of things and just couldnt see anything in the mode positions that co insided with this.Any how it has also failed when not in motion at all but only once and im hoping this is not a preveiw of something worse to come.It also has the last 2 digits in all of the axises flashing but it does'nt seem to worry its positioning when comanded however the hand wheel seems to drift of position in that mode when you let it sit and I was wondering if this has anything to do with this error that comes up at y axis feeds above 3000,anybody out there seen this before with a heidenhain 2500 control.Thanks in advance.Greg.
