RPM of rear fan not in range!

Hello

Sorry for my english, i am spanish.

Today I got the coveted sl1, unfortunately, when doing the "wizard" has given an error "RPM of rear fan not in range", I tried to disassemble the fan, observe it and have done several tests, removing the particulate filter , with orange lid open, closed, etc ...
I have passed the "wizard" and I have made a calibration, when I started printing a test piece it has given me again the error that the back fan does not work, at the moment the fan is working and the impression I am doing.
Any idea what it could be?

the complete error :

RPM of rear fan not in range!

Please check if the fan is connected correctly

RPM data: [1111, 1111, 1500, 2142, 2307, 2000, 1666, 1250] avg 1635

RE: RPM of rear fan not in range!

Let me join you. I am stuck at exactly the same error, after boasting about my construction ability. In my case the average speed is only 1450 or so. I did the same troubleshooting as you did.I note that the advanced settings show a rear fan speed of 1000. I have whined to info@, but have not yet had a reply

Support response from William Holm. He starts by suggesting factory reset and reflash firmware even if that was done recently.
