AnHardt fd0e81b0c7 Distinguish between BUZZER and SPEAKER (PR#2513) 
A speaker needs a AC or a pulsed DC to make a sound, a buzzer only needs a DC.
A buzzer has it's own resonator. It works in most cases to feed the buzzer with a pulsed DC, but the sound will not be as loud as with pure DC.

There seem to be boards where the BEEPER-pin is not able to handle a PWM. Obviously intended for a buzzer.
To make these board able to handle a speaker

* replace the PWM based tone()-function again with a on-delay-off-delay loop.

Hopefully the last time I touch the beeper code.

Example Configuration for OpenBeam Kossel Pro BRAINWAVE_PRO

  • Configuration files for the Openbeam Kossel Pro as delivered in their KickStarter distribution

I @Wackerbarth tested this version on my Kossel Pro and Arduino 1.6.5 for Mac. This configuration is a transition to merge Terence Tam's configuration with up-to-date Marlin source and a current Arduino IDE
