On the CORE One equipped with the INDX, the offset of the tools compared to the first is calibrated through the Tool Offset Calibration. If the offset of one of the tools deviates too far from the expected range, the printer will show the following message: "Tool offset calibration failed. Make sure the nozzle and the sensor are clean. Caution: the nozzle may be hot."
Error name: Tool offset out of bounds
Error code: #36130 (CORE One INDX)
Make sure that the filament is unloaded before the calibration process.
Use a small brass brush to clear away any old plastic stuck on the nozzle. Avoid contact of the brush with the hotend cables, as this could cause a short circuit.
Go to the printer menu in Control -> Calibrations & Tests -> 12. Tool offsets calibration and redo the calibration.
Any vibration propagated to the surface under the printer, or an unstable surface under the printer, might cause a false reading on the load cell, triggering the homing error.
For example, a printer that is in operation next to your printer can cause vibrations that are propagated to it, potentially causing a tool offset calibration failure. In that case, stop any printers next to the CORE One with INDX, and reattempt the calibration.
A possible solution to dampen the noise and vibration of a printer is to add some additional padding underneath the printer.

Even stranger, during the calibration, some of the tool heads are probing the sensor on the front right corner. That can't be good for the board. Hopefully they have a better guide to troubleshoot...
When Printing, the nozzle temperature is higher than during calibration, and it appears that there is a slight amount of filament dripping from the loaded filament... but it's really just a tiny amount. I tried using both Prusament PLA and
ESUN PLA, but both yielded the same result. Since performing the INDX conversion, I haven't been able to print a single time.
please try to use 6.9.1 beta (or stable if released by the time you are reading this reply). One of the changes we did there is redusing the nozzle temperature for the tool offset calibration.

Unsafe Z tool offset #36131
Always during Z-probing and sometimes it even stops 4-5 mm from the sensor.
