Topic: Pillow block mod done. Circles still up to -0.5mm diameter deviation

Any advice would be great.
I've played around with belt tensions on x and y,
Square dimensions are fine.
The diameter is typically -0.4 across 11 o'clock to 5'o clock.
I have 2 pillow blocks that were installed with zero belt tension on the shaft, one near the y-axis stepper motor belt attachment and the other on the opposite side.

Are both Y-axis belts to the carriages tight? I don't really have many guesses though, as I never had much problem with circles and the pillow removed whatever I had.

Sorry sad

I'm slacking them right off and trying again. Any chance you could post the measurement your belt screws are extruded from your y carriage so I can compare please?
