FAN 0 connector not working (Board faulty ?!)
-
Hi there,
first of all thanks for this awsome piece of hardware !
And please excuse my bad english
I recently set up everything and got it running after a few tweaks.
But im running into a problem, not being able to control the fan 0 portOthers work just fine… M106 P* S1 (Same Fan used for testing on all ports)
When i measure those i get stable 24v from other ports but on port 0 only 3.2 -3.5because i need some prints to switch to my new printer i tryed to remap P2 to the extruder/tool 0
M563 P0 D0 H1 F2 ; Define tool 0but i doesnt work (even when tool is active)
Manual M106 P2 S1 works...I double checked if fan is in temp control mode or inverted but its not.
FAN Conf:
M106 P0 S0 ; (supposed to be Partcooler)
M106 P1 T45 H1 ; (Hotendcooler)
M106 P2 S0 ; ( spare part cooler - but cant get it running with remap)may my board be broken ?
im thankfull for any advice or helpgreetings from germany

No quite sure I understand the problem. The S parameter determines to PWM fequency, so S0 will effectively turn it off. S255 will turn it on at full speed. https://duet3d.com/wiki/G-code#M106:_Fan_On.

you can send like M106 S0.5 which is 50% PWM 0.6 = 60% and so on
but i tried 255 with the same resultsProblem is that i cant get port 0 working like the other two (with same commands) -switching it of S0 gives 0 volt
ON gives 3.x volt
-
Ahh I see. Is the 3 volts with the fan connected or disconnected?
-
disconnected
is there any kind of support ticket i can open for this - im about 80% sure the board is faulty
-
Im a little disappointed not getting any "official" support here…
Website says better use forum instead of writing mail - dont want to return the board - prints really good - but allways turning the fan on per hand sucksi'll try mail tomorrow

It does sound as though the Fan0 output is faulty. In such cases you need to email the supplier that you purchased the board from, to arrange a replacement.
