Hello
I have a Prusa i3 pro B with GT2560 REV A. I use Marlin MK4duo. I 3d printed a support for the fan cooler, it's connected to the PWM_FAN, it works with inverted logic there is a problem, when I switch on the 3d printer, I put the fan speed at the value 0 but the fan blow. How can I stop it? I tried all the frequences and values options but I didn't fix the bug.

Are you sure that Marlin MK4duo is compatible with the GT2560 board? It sounds like either something is wrong with your connections or the firmware you are using is not compatible.

MK4DUO is full compatible. The printer has the same problem with the original firmware.

Send the code "M106 S0" to test?
