On the multi-tool versions of the Original Prusa XL, the offset of the tools compared to the first is calibrated through the Tool Offset Calibration. If the offset of one of the tools is too high compared to the expected range, the printer will show the following message: "Tool %d offset %c: %.3f is out of bounds [%.3f, %.3f]".
Error name: Tool offset out of bounds
Error code: #17104
Check if the nozzle is pushed into the heatsink. Ensure that the nozzle is correctly positioned.
Make sure that the filament is unloaded before the calibration process, and that there is no filament residue under the nozzle.
