THE TEST DISC | Z-Offset Calibration Disc

THE TEST DISC Simple, yet VERY effective way to dial in your Z-offset to perfection. Notice the change in the image. From right to left, as I adjust (Baby Step up/down) the z-offset. Example: I started at a z-offset = -0.98 (which felt good on a “paper test”), using this calibration tool, my z-offset ended up at -1.11 (perfection).
