Installed the Dual touchscreen and Marlin, configured the solenoid to switch hot ends, then verified both extruders worked. While testing #2 extruder, the solenoid started to buzz and now it will no longer respond. Looks like it has failed, hopefully not the driver board.
Hi, Hothead #1 heats up as soon as power on, raises to 270C won’t tuen off and can’t control via touch screen. Hothead #2 working fine as is bed. Any pointers. James
