I have been using the smart effector reliably for the last 4 years and recently noticed that the LEDs were dim, which was preceded by some flickering. I have it set up for 24V and am not sure what would have happended for the LEDs to just become very dim. Of note, I just swapped the control board - and the extruder fan is connected to a 24V connector (because the printer power supply is 24V). Why would this just happen? Do the smart effector components, e.g. resistors, have a lifespan? Could it be dust? Thanks in advance!
