As the thread title suggests, I've run into a weird new feature on the EZBoard Lite. My parts cooling fan port fan1 is no longer controllable and stuck in the always on 12V position. I've tried resetting the EEPROM reflashing the firmware, setting speed through the controlknob and through octoprint, but it's always outputting 12V on the pins. Any clue what could be wrong or how I could troubleshoot this issue?
To prevent some back and forth. Yes I've checked all the fans if they are connected properly. I have the fan on the hotend heatsink plugged in to always be on, the casefans are plugged into the fan2 header and they spin up and spin down just fine. It's just the fan1 header that is giving me issues. I'm certain that it used to work, but I do admit that I was not present or aware on when exactly this problem occurred.
