Hello! I bought a refurbished Lulzbot Mini about 9 months ago, and it has been acting great up until recently. About two weeks ago, I noticed that the temperature readings displayed in Cura were diverging slightly from the set temperature, usually by no more than 4-5 degrees. However, today I started printing and noticed that the bed temperature readings are differing significantly from the set temperature, reporting readings of as low as 2 degrees or as high as 118.
Would this be an issue with the connection between the sensor and the control board? How would I go about fixing that? Is it some other issue? Any help would be appreciated. Thank you!
