The printer is displaying the message: Incorrect RPM reading of the fan. The print may continue, however, there's a risk of overheating.
Warning name: Expect overheating
Warning code: #10714
This warning is shown when the RPM of one of the fans is out of range during the print. The warning can be ignored and the print can continue, but if the printer overheats the print will be stopped.
The SL1 has three fans: the LED cooling fan, the filter fan, and the right blower fan. If the warning appears, please follow maintenance steps for the fan that generated the issue: SL1/SL1S maintenance [進行中の翻訳]. When doing that, also check the cable connections of the fan to the mainboard.
If the right blower fan is the one that showed the warning, make sure that the blower gasket is still in place.
Go to the printer menu in LCD menu -> Settings -> Calibration -> Wizard. The printer will run the self-test. In case the fan also fails during the self-test, switch the connection of two of the fans, and see if the warning will be transferred to the new fan. If the error is transferred, the fan that had the warning originally may need to be replaced.
