How to make your 3DPrinter Sing

The Internet is an amazing place. And we can find all sort of content related to 3DPrinting.

Most of the printers can be controlled with an Arduino, and the premise of an Arduino is to connect all kind of sensors, small engines or a buzzer…

So first things first. Let’s go to our RepRap Wiki to see our GCode Commands list. If you search for a command like M300 you will find this:

 

 

That is the first thing that we need to make this The Voice Printer.

Make your printer play the beep on the buzzer can help you on two things: Tell you that it’s about to start a print job after the heating, home and bed leveling, and tell you that the print job it’s finished. However, nothing stops you to make that noise something nice to hear(And not make your ears bleed).

Well, so what do you need to do this:

• Check if your firmwares support the M300 command
• Connect a buzzer to your printer
• A GCode file.
• Choose the song that you want to play

The M300 command needs to have two inputs, the S parameter that will receive the frequency in Hertz that the buzzer will play the song and the P parameter that will be for how long the song will play. So, using a few M300 on your GCode you can make a Symphony.

What I found is that you need RTTTL text. RTTTL stands for Ring Tone Text Transfer Language, this language was developed by Nokia a lot of years ago to make your phone play custom songs. So around the web, you can find a lot of RTTTL samples that you can use on your printer. Here is a example of how a RTTTL code looks like:

[code]

smb:d=4,o=5,b=100:16e6,16e6,32p,8e6,16c6,8e6,8g6,8p,8g,8p,8c6,16p,8g,16p,8e,16p,8a,8b,16a#,8a,16g.,16e6,16g6,8a6,16f6,8g6,8e6,16c6,16d6,8b,16p,8c6,16p,8g,16p,8e,16p,8a,8b,16a#,8a,16g.,16e6,16g6,8a6,16f6,8g6,8e6,16c6,16d6,8b,8p,16g6,16f#6,16f6,16d#6,16p,16e6,16p,16g#,16a,16c6,16p,16a,16c6,16d6,8p,16g6,16f#6,16f6,16d#6,16p,16e6,16p,16c7,16p,16c7,16c7,p,16g6,16f#6,16f6,16d#6,16p,16e6,16p,16g#,16a,16c6,16p,16a,16c6,16d6,8p,16d#6,8p,16d6,8p,16c6

Wait a minute… Lays, How am I going to use RTTTL text? I need a GCode!

Do you remember that 3DPrinting is what it is today because of the Community? So, don’t fear my friend, I have the solution. =D

Colin Edwards, most known on GitHub by the name DDRBoxman created a system that gets the RTTTL code and turns into a GCode snippet that you can append to your GCode file. So, the RTTTL sample that I used above, in GCode flavor looks like this:

Those samples are from a game that everyone knows, and I will let you discover which one is it. (I wasn’t able to add the audio here =/ )

So, Lays, that looks fun, but How am I going to do all that?

Sit back and enjoy life for a second now.

First, you can find all kind of Arcade songs on this website, there you can get the RTTTL code and convert to GCode on Colin website, after that you just need to copy the generated GCode and add to the begin or end of your GCode. If you don’t want an Arcade song, you can put the name of the song and append RTTTL in the and on Google and search around until you find your song.

Well, let me know in the comments if you found out which song I used in this post! Don’t forget to subscribe our mail list to get all the news.

Enjoy Life!

That’s all folks!
