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 Vellemann K8200

  • Configuration files for Vellemann K8200 (with VM8201 - LCD Option for K8200)

  • K8200 is a 3Drag clone - configuration should work with 3Drag http://reprap.org/wiki/3drag, too. Please report.

  • updated manually with parameters from genuine Vellemann Firmware "firmware_k8200_marlinv2" based on the recent development branch

  • VM8201 uses "DISPLAY_CHARSET_HD44870_JAPAN" and "ULTIMAKERCONTROLLER"

  • german (de) translation with umlaut is supported now - thanks to @AnHardt for the great hardware based umlaut support

I @CONSULitAS tested the changes on my K8200 with 20x4-LCD and Arduino 1.6.1 for Windows (SD library added to IDE manually) - everything works well.
