Print fan failing rpm test
- I have a MK4S (upgraded from a MK4, that was upgraded from my original MK3s+).
- Print fan is operating at ~5150 rpm at 100%, but is still failing during calibration test. I have removed fan and tried it, checked all the connections and wires (all were good to go), preformed a deep clean on the assembly, used grease less lube on the fan itself as a final test but it still maxed out at ~5150 rpm and fails the initial calibration test.
- What is the rpm cut off for failing calibration for the print fan?
- Is this a software or hardware issue?
