I think my Y-Axis rods are sagging?

[thor2257]

So this is where I am at 1 year later and getting good prints but having leveling issues all the time. I can level my HBP with a glass bed at the 3 points and using a dial gauge be at .00 mm at each. I move to the center, left center and right center ,and get -.06 (ish) every time. So it seems that the y-axis rods sag ever so slightly in the middle causing the plate and nozzle to be too close. I have fiddled with it and got it to work but with a modified z-axis and accepting I can only print at .2 layer height unless I change settings. But the goal would be not to compromise. DO you think just removing the left extruder setup would fix the sag? Is this the best solution? Thanks.

Don't forget about the weight of the dial indicator and its mounting. Plus .05 isn't much. These things aren't that precise. I used to use a dial to level and realized I was creating more issues than solving and went back to a trusty piece of paper and my eyes to tell me what is good.
