Belt tensioning problems
I have been having trouble following the guide for belt tension. I have a semi assembled XL. After failing input shaper calibration, saying X belt was too loose, I checked on the belt tension guide.

The app to measure the belt tension worked nicely, tried two phones and they showed just about the same results.
After measuring the belts using the app I tried the alignment test and found out that the right side did have some play, but by tightening the right tension screw, the belt obviously gets stiffer on that side. After trying it numerous times I'm now sitting at
Left belt: 84hz
Right belt: 94hz
Alignment on the right side still has about 0.4mm play, if I tighten the right tension screw a little bit it goes away but then the tension for left belt will measures at 102hz.
Am I misunderstanding something, are there any other screws I should be looking at or will repeating the steps of adjusting the tensions screw do anything?
However though, with the 10hz difference and 0.4mm play on the right side, the homing tower prints perfectly.
Should I be worried that the frame is not square etc. and if so how can I make it better? ...or just print happily and don't ask questions?
