Hotend fan problem
I get the error message shown in the attached file.
Hotend fan not spinning Check it for possible debris, then inspect the wiring.
![](\Users\admin\Pictures\2024-07-18 15.14.16.jpg")
The problem is that it does not tell me what fan to check. The wiring appears to be solid, and since I don't know which hot end it is referring to, and I could find nothing about how to check it for debris, I have no idea what to do. But it refuses to print.
What happened to that idea that error messages would display a QR code that would take me to an explanation?
All attempts to locate this problem in search give me non-XL solutions.
RE: Hotend fan problem
You can check which Hotend it is by first setting Hotend 1 to 100°C. If its ok then check the next one and so on.
Yes it should point out which Hotend it is related to. First and foremost it is the one you start printing with.
