Heater stops when Cooling Fan starts
-
Hello everyone,
I have a 12V power supply on my duet Wifi/printer
I have recently added a 12V fan to cool the print (I was previously using a 5V fan)
So I moved the Fan Jumper and plugged the new fan and started a new print.
1st layer no problem (fan is off)
2nd layer, fan is switched ON but the Heater just stops...
I have tried again and each time the FAN starts , the heater stops to heat.
Have then unplugged the FAN (just to check) and everything is OK, no problem till the end of the print.
What could be the problem ?
Thanks
SR

Are you getting any error messages about heater faults?
-
Yes, but I think I know what's happening...
I think the fan is strong and blows on the heater making the thermistor thinking that the heater is faulty while this is only coming from the air blowing.
Gonna put a silicon around it and test... Don't think now it's an electrical problem.

Yes... that's it .
So I see two solutions here.
1] Put A silicon around the head
2] Turn the head so the thermistor is not facing the air fan flow.
Or both

Or bothEven better is to adjust the fan duct to blow at the print below the nozzle, not at the heater.
