Hi all, first time poster here and very inexperienced with software and configuring it.
I have a very old Mendel with a Melzi 1.0 board (original from 2013)
The other day the bed thermistor failed and the bed did not heat. That's understandable.
I replaced the thermistor with another of the same type. The temperature is reading about -19C. The thermistor checks out at about 100k ohms.
I swapped the bed and hot end thermistors but the problem is still there.
The bed thermistor does detect changes in temperature but because its reading 30 lower than ambient temp it's preventing the bed from heating up.
Any ideas what's going on? What can be done to fix it?
Any help is appreciated as it's stopping me from completing a very important project
