Topic: Test Extruder Fan?

Is there a way to kick on the fan to make sure it's working?  I don't see a way in Repetier.  I could obviously take it out and test, but I want to make sure the printer is kicking it on.
Thanks.

Re: Test Extruder Fan?

On a Da Vinci, it runs any time the printer is on as it's purpose is only to cool the extruder neck.

Printing since 2009 and still love it!

Re: Test Extruder Fan?

Fan start only if temperature is above 50 degres in normal mode

to have full control using M106/M107 there is an option in FW:
#define REPURPOSE_FAN_TO_COOL_EXTRUSIONS 0 //Setting this to 1 will repurpose the main Extruder cooling fan to be controlled VIA M106/M107
//Warning: for DaVinci 1.0 need to add a permanent fan with power supply to cool extruder

Thanks, all!  I did notice it kick on once the extruder heated up.  I just wanted to make sure it was working.  Thanks again! smile
