Extruder is not heating

[ddkhw]

Hello,
after some successful printings now the extruder isn't work (heating) anymore. The heating is out of order.
Cable/Connector are ok, no visible damages. How can I detect the source of failure. Is a wiring diagramm and/or measured values available?
Thanks in advance.

I am having a similar issue. I was printing fine but then each print would require a higher temperature in order to print otherwise the filament would start grinding and skipping. I actually don't know what exactly my problem is. Maybe the hotend needs to be cleaned. I am in the process of doing that now but I don't think it is the answer. I posted a new topic requesting help or ideas but still awaiting approval by a moderator.
