I am working on installing a new BIQU MKS Base v1.6 mother board with chimera dual hotend in my Ender 3 which has gone well up until trying to tune the hot ends. So far, I have everything hooked up properly, and the thermal sensors are reading the hot end temperatures but when i go to tune the voltages, the opposite hot end, H1, heats as fast as possible and as hot as possible until Marlin kills the printer and stops everything (thank goodness for thermal runaway). During the test, H0 has a nice and smooth curve as it heats gradually but never gets close to calibrating thanks to H1 running away. I have looked at the settings but nothing jumps out as being the magic setting to stop this from happening. I have attached the configuration files for Marlin that I have uploaded to my printer to help. Would appreciate any feedback or settings that could help with the hot ends.
