[SOLVED] Part-Fan not running
-
Put Fan0 directly to Duet, Fan5 to the Effector. And running Tool with Part-Fan 0:5 and it will at least not come from Duet, cause if the Problem happen, Fan0 will still run but Fan5 will stop.
-
Further Test:
Even if i remove the Haydn Rods and hold the effector in my hand. As soon as a go down the Fan stops.
Will now try to put a long cable from FAN0 Port on Duet to a further Fan without connecting it to the Effector and try if this makes a difference. But i'm somehow running against a wall...

If it's sensitive to position, it sounds like a bad crimp connection in the fan cable to me, or possibly bad soldering where the 6-pin connector is soldered on to the effector PCB. Does the soldering look OK? Can you make the fan turn on and off by waggling the cable?
-
Will try. Using iwiss Crimp-Tools all the time and never have had a bad crimp. Thanks for getting back.
-
Have waggled as hard as i can, no difference. As expected the Crimps are good enough.
Anyhow, i've resoldered the PF+ and PF- Connection. It's getting better, cause now i can lower Z additional 20 Centimeters before the Fan will shutdown.
Will at least try a longer cable without the 6pol Connection to get the fan running. If this will work, i know at least that this is more a less a problem with the Terminal. Maybe i'll solder it out and replace it with something different.
-
Did you check visually the soldering of the 6-pin connector on the underside of the Smart Effector?
When crimps fail, sometimes it's due to a wire fracture inside the cable close to the crimp, or a pin not locked into the shell. In such cases, pushing the cable down into the connector is sometimes what makes the connection again temporarily.
-
Indeed it will be the Terminal. Putting in a Fan directly with a longer Cable directly to Duet will work everytime. The Connection looks somehow okay but i never trust flux. And without calling me hero, i'm doing crimping mostly every day and my tools are great. Never had a failed Electronics due to bad crimping. And after resoldering a little bit it is getting better.
Later, if i'm able to spent the time, i'll completely resolder the Terminal.
Thanks so far David.

Have to correct myself. It's not the 6Pin-Terminal. Have soldered the Cable directly to the 2Pin-Connector of PF+ and PF-.
Here the Problem exists. It seems that here exist a problem. As said, have now used a Long-Cable and run the Fan0 directly. No more issues.
Cheers

A further Check seems that the Effector is the Problem here.
Now, i've tried again the Calibration of my Delta and whoops. The Effector triggers itself around the same Height, as the Fan goes out before!
Is there a Way to "Reset" the Effector in same way? Currently it triggers at a Z-Height of 100mm!

My Printbed will introduce a big magnetic Field above 48°C ....
Therefore only Option is to use B1 in the M558-Command ...
