Geeetech

Hi Guys,

iam new to the Geeetech world (Mostly got anycubics).
I got a new A10 "pro" wich has installed the "new" GT2560 V4 Board.
The problem is the partcooling fan is alwas 100%

So i have searched the web and found different solutions. iam sure its not a jumper problem, because i can meassure 24V at the fan port (on all speeds like 0-255). Also i found the pinned thread about activating the PWM in the firmware.
But it seems there are no sources for the V4 Board (with bltouch enabled) online yet?

Is there another solution for this?

Thanks in advance

Hello, maybe there is something wrong with your fan. If you need to replace the accessories, please consult the Ticket system on the Geeetech official website.

Dear William,

i have already replaced the Fan, its the same.
Iam not pretty sure how PWM works but the voltage remains always 24V even if i use the Gcodes to turn the fan off
