On the fly bed level test

thingiverse

To identify inconsistencies in your bed glass, perform a test even after spending $20 on it. Ensure perfectly aligned bed corners but still face issues? Monitor print variances with a toolless setup using thumb knobs for ease of adjustments. This method helps you detect first layer print problems and make necessary adjustments mid-print. Focus primarily on the initial layer, as it's crucial. Additionally, observe retractions and restarts in the subsequent layers.
