Update for v19.01.22 (PWM) ? about marlin-ai3m HOT 7 CLOSED

I will compile the latest stable with the PWM settings when I get home and post the download link here.

I won't do those regularly since there are many different branches, but I will write some instructions on how to edit the newest releases yourself for settings like software PWM later today.

Fast as lightning :)
Thank you very much!

Resetting EEPROM to default with M502 + M500 is recommended on the latest update.

Sorry for asking noob questions, but what is this PWM for?

It's a certain way of powering the fan. Needed for some particular fans like from Sunon. Not needed on the stock one.

Kann man die PWM Frequenz in der Firmware anpassen? Ich meine gelesen zu haben, dass Default 500 Hz sind - benötigt würden aber 100 Hz (ich teste das morgen mal aus, sollte ja hiermit möglich sein: M106 P0 F(Frequency-Parameter). Mit der aktuellen PWM Firmware fängt der Lüfter bei niedrigen Drehzahlen an sinusartig zu "stottern".

I'd recommend you to look into editing and compiling the firmware yourself and try out some changes.

There is no F-parameter on Marlin's M106. Refer to Marlin's documentation, other GCode docs might list other firmare's capabilities.

Check this page to learn more about editing and compiling. I have added a section on PWM settings.
