Heatbed failure in Mini selftest and heatbed calibration test
I have two Mini-s that I am trying to get running. When I do the selftest of the components, I get a failure at the very end of the selftest while testing the heatbed. I have run the self test on both of the Minis simultaneously and have gotten a failure (on the heatbed) on both machines. What is the chance of that? I put both machines into factory default mode and have gotten the same results. I have loaded the most recent firmware (4.3.4 firmware) with the same results. The error code says to check the heat bed plugin and connections (which I did) and got same result. What am I missing here? Is this a firmware issue of these Minis, or are both having some kind of hardware issues? I purchased one in 2019 and the second in early 2021. Both have very few hours on them, I would say less than 50 on either of them.
Any suggestions, anyone?
Your help is appreciated.
