Multi-toolhead Offset Calibration again.Heated Bed Leveling is enabled.V1.5.2 fixes the first-layer issue introduced in V1.5.0 that could still occur in certain scenarios in V1.5.1.
However, first-layer quality is affected by more than just the firmware. It also depends on factors such as the printer's condition, printing environment, and print settings, including bed mesh data, multi-toolhead offset calibration, build plate flatness, filament condition, and first-layer print settings.
As a result, first-layer quality may still vary from one printer to another, even when running the same firmware version.
If your first layer is still not as expected after upgrading to V1.5.2, refer to U1 model warps, detaches or collapses and follow the troubleshooting steps provided.
If the issue persists after completing the troubleshooting steps above and appears to be firmware-related, please contact our technical support.
