Thread: Positive backlash???

Hi All..
Finally getting down to some fine tweaking... In trying to measure any slop, and I am sure I have some as my X and Y are chain driven, I have been machining some slots 100mm long..
First I move the X axis in the +ve direction, then machine a slot also in the +ve direction.. Reckon there should be no backlash at this point.. Then I move a few mm across the y axis and machine a slot in the -ve direction of the X axis.. This should, by my reckoning, then show up any backlash and I was expecting the second slot to be shorter...
But no..! It was 0.2mm longer... Have repeated this several times with the same result..
And, as always, when I get to scratching my head too much, I pop here to see what silliness you guys can point out that I am doing..
Thanks
Steve..
