Thanks for the help! I had looked at the config.g file and all the M305's were the same so I was scratching my head. Google does not help much for finding an answer like this. It is funny because I found the settings for the different thermistors, but did not find how to set them in the config.g or what ever file it needed. Anyway, it is reading correctly now.by minifiredragon - Ormerod
I self built an Ormerod 2 printer. In the processes I ordered to 100k thermistors missing the fact the bed was a 10k thermistor. I did not think it mattered, but it seems to as the Duet electronics reads the bed at -19. However, when I plug it into the hot head temp monitor it reads correctly. I am running 1.14 dc42 firmware (just started commisioning the unit tonight). Is there a way I can tby minifiredragon - Ormerod
