GT2560 : no control over PWM-Fan
Hello,since 2 days I lost controll over the PWM fan.The fan start spinning at full throttle afer power on the printer (Prusa I3b).Tried to send M107 - no reaktion - the manual controll slider in repetier host isn´´t working too.Reset-button on the printer LCD-Panel (reboot) doesn´t solve the problem.
