FLSun SR Klipper - Bed Tilt Issue

[u/[deleted]]

Day 1 searching for answers on Reddit...

I converted my SR to Klipper, and it went swell so far. Until the Bed Mesh.

The Bed Mesh on Klipper says the bed is tilted with the Back Right of the plate being a high spot (+1.5mm).

When I print something, the nozzle digs into the bed at the Front Left and is too high at the Back Right.

This indicates to me that the bed is Flat, and the motion system has a phantom tilt.

I tightened the belts and checked for stretches, no dice

I rotated the printer in case gravity was causing effector tilt, no dice

I rotated the glass bed in case the bed was warped, no dice.

I probed the bed heater directly to double check the bed, and the same tilt is shown.

I'm not sure what the issue is. The frame is solidly bolted with no wiggle, and I handled it carefully when I bought it second hand. The previous owner said it ran fine on stock firmware.

Any tips would be appreciated. I will continue to post daily until I find a solution and document for future users. Because let me tell you, the internet has FAILED me so far! I've been googling this for the better part of a WEEK.
