Heatbed problem - Self Diagnosis failure

Hi,

I have my Mini since June 2020 and it ran many successful hours (I assume something around 250h?). But the last few prints are more and more problematic - some areas on the build plate have a higher chance to fail the print because the PLA does not stuck to the plate.

I ran a Self Diagnosis and there was an error with the heatbed. The printer heats the bed to 100°C, but fails to get there in time and the Diagnosis stops at around 67°C. After this test I preheated the bed to around 60°C and touched the build plate with my hand (of course carefully). I do not have a thermometer to measure the surface of the build plate, but it didn't feel like 60°C. More like a warm 30°?

I followed the guide https://help.prusa3d.com/en/article/heating-failed-bed-print-head-mini_112444 and the cables are connected and are not broken. I do not have Multimeter to measure the resistance or do any deep analysis.

Is there anything I can do? Do I need to contact the support?

RE: Heatbed problem - Self Diagnosis failure

Adhesion, or lack thereof, is most often oils on the print sheet. Really. Alcohol isn't the best way to clean the sheet, either. Really.

That said, if you are also having a heat problem, contacting Prusa Support via CHAT is your best next step.
