I am using a volcano copper plated colvano heater and a copper plated volcano nozzle with a 30W heater on a smart effector. Everything from e3d and duet3d.
I found a similiar issue in another topic, where people should increase their dead time.
I also found this solution in the troubleshooting too: https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control
Coming to my issue:
After assembling everything and running a PID auto tuning, my printer already seemed to have heating problems above 260°C. So it was not able to set a auto tuning max temperature of about 280°C - only faults. My printer set a dead time of 5.5.
When I now want to start heating the nozzle to 200°C for example, my printer receives the following error message:
"Error: Heating fault on heater 1, temperature rising much more slowly than the expected 1.4°C/sec"
I changed the dead timer to 20 and 30 seconds. I deleted my override.config to ensure heating would go up again. It worked, but the temperature is now exceeding the targeted temperature:
"Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C"
Do I need to run another auto tune and change the dead time within the override.config?
Or how could I solve this problem? I have checked wires and connections to exclude other issues.
With my normal volcano heater I never had this problem before.
Many thanks in advance
