I have burnt my A6SHB Fan0 Transistor on my new GT2560 V4

Post by cabfire » Sat Apr 25, 2020 12:20 am

Hello everybody,
By changing my cooling fan on a Geeetech A10 with new GT2650 V4, I have made a mistake and created a shortcut :-(
So the Fan0 A6SHB transistor on the mother board has burnt :-( and now I have 5V instead of 24V tension on Fan0 power out.
Do you know a way to connect the "Adapter Hot End plate" to the Fan1 power out of the Mother Board ?
I guess repairing should be too difficult to change the transistor. Finaly the best way should be replacing the mother board but I think we can simply use the second Fan no ?

Hi,you can directly change the interface to Fan1 or Fan2.

Hello William
Thank you for your prompt answer.
I have plug my fan on other interface of the "Hot End Plate Interfaces" as you can see on photo (Num 2 output)
But I have only 5V here and gcode instruction seems not working (M106 P1 S255 for example, the same with P2)
Num 1 was the output interface used for fan when I burnt the transistor. I have only 5V here and gcode instruction M106 S255 doest not work anymore.
Finally I use the num 3 interface but it is not possible to manage it with M106 S0 or S255 gcode with P value at 0, 1, 2 or more.

I guess the both 1 and 2 outputs of the "Hot End Plate Interface" is powered by the single mother board Fan0. And output 3 is like the output below itself and probably powered by another MB power output (other than fan0,1 and 2 MB outputs)

But May be you wanted to talk about Mother Board Interface to change directly fan 1 or 2 ? In this case, is there a way to change from fan 0 to fan 1 or 2 and power the "Hot End Plate interface" for the cooling fan (See photo 2 of Mother Board) ? It should be possible no ?

Thank you again

Hi,if the fan is not controlled, you can only replace the motherboard.

yes Fan for Nozzle is not managable :-(
I have ordered a GT2560 V4 just right now on the geeetech web site.
Hope it arrives quickly because for the moment I have temporarly made a manual workaround (see photo) to switch on/off the cooling Fan :-)
