My U1 has printed about 94 hours so far, it has gotten two pogo pins error message after completion of print job. Each one occurred about 50 hours and both were resolved by cleaning the pogo contacts and pins with 99% IPA.

Is it normal to happen this frequently? My U1 is in an enclosure with exhaust and I’ve only been printing PLA and PETG. The fume build up pogo contacts shouldn’t be this fast.
