AP/TH board troubleshooting
Can I have you navigate to the controls menu and let me know if the temperature readings are normal or if the nozzle temperature is not showing a correct ambient temperature. I am mainly looking for the temperature shown in section 1 of the picture below and if possible can you send me a picture or video of the temperature reading?
The next thing I would like to check is the AP board of the machine. To access the AP board you can reference this guide (AP board) and I would like some pictures of the front and back of the board and can you also check if the 2 lights are lit up when the printer is turned on with 1 of them blinking? You can refer to the image below for the lights of the board. (Please note that the USB cable on the right side has a specific orientation that should be noted if it is removed) The pictures below show the lights that we expect to see and the back of the board where a capacitor can be blown causing this error.
Finally I would like to check the TH board of the machine to check for any damage. To access the TH board you can refer to this guide (TH board) and it is shown in step 7. Can you send me a picture of this board to check for any damage?
