IR sensor troubles, hotend fan not running too

knutselsmurf

I am testing the IR-sensor, it works but I can't print..

2 issues:

after calibrating (using the method from https://miscsolutions.wordpress.com/mini-height-sensor-board/, I started a testprint. When it starts the bed is raised too high: the melted filament can't get out the hotend and after some time the tube-clamp is pushed out the top of the hotend.
something else: when the hotend is heated up, the hotend FAN is not running: I can start it by moving the fan-slider in the duet browser panel, but that is not what we want ofcourse.

Below my configuration, I have used the webbased configtool but it looks it's not making the right configuration (ofcourse, I loaded the zip-file when it was ready with the configuration..)

Maybe the IR-sensor is not a good idea to use ? (I have the orginal dc24).

I hope somebody can help.

Many thanks in advance!

Regards,

Arthur

@knutselsmurf said in IR sensor troubles, hotend fan not running too:

adjust with babystepping until its fine. then apply the babystepping to the offset.

something else: when the hotend is heated up, the hotend FAN is not running: I can start it by moving the fan-slider in the duet browser panel, but that is not what we want ofcourse.

what firmware version are you running?
also you dont have a part fan configured. all your fans are Thermostatic control
