@PUGCanada I have an Ender 3 Pro also with a Maestro also.
it may not sag but it might be out of align with the other side.
I have to measure between the top of the leg and the X gantry on the left and compare with the right.
The right hand side might feel that it has no play, but please check the height.
I have found a difference of 5 - 10mm either too high or low and requires the occaisional 'tweak'!
My guide wheels are tight too, but the occaisional headcrash, me not watching what I am doing, i just check it as a sanity check!
HTH. Paul.
