Verify heater error in hot end

One pretty hands-on approach could be:

  1. Disconnect everything from the PSU
  2. With a multimeter, measure its no-load voltage across the V-out (+ /-) clamps → Should be 24V
  3. Take the heating cartridge out from heat block
  4. Put it on a fire-proof surface
  5. Connect it to V out of the PSU
  6. After a while, the cartridge should even start glowing red
  7. If not, measure again the voltage on the V-out clamps → If it is significantly below 24V then likely the PSU is faulty
