How did you measure it?
I used calipers and measured the distance between the edge of the top opening and the top of the hot end. It is a very nice set of certified calipers that were given to me as a graduation gift, so I am inclined to trust their stated precision and accuracy.
Process:
0) After homing, lower the bead out of the way move the print head to 90 mm along the x-axis.
1) Run the head out to 100 mm from left to right and measured the distance.
2) sent the head out to 110 mm, then back to 100 mm and measured again.
3) repeated about 5 times
4) repeat process around 50 mm
5) repeat steps 0 through 4 with y axis
From the results I computed backlash as well as steps/mm.
I was happy to at least find that the measurements were very repeatable (all within +/- 0.02 mm ); the backlash measurements at 50 mm and 100 mm gave very close to the same results; and the computed steps per/mm were essentially the same for both the y and x axis.
