Toolchanger Docking Sensor Read Failure
The XL-Buddy master board failed to poll or read the Hall docking sensor status across the modular differential RS-485/I2C toolhead bus on a specific tool carriage, triggering a safety interlock during tool changing operations.
Loadcell Tare Out of Range
During the pre-homing/mesh-bed leveling sequence, the strain gauge loadcell failed the auto-zero (tare) offset baseline verification. The analogue voltage output or raw ADC counts measured by the LoveBoard exceeded allowable tolerance margins, preventing safe bed probing.
