cnc Music!!

[kram242]

I just wanted to know if anyone has come across or made any gcode that can make your steppers make music?!
I have seen a couple videos of machines doing this but I can on find a dasiy.nqc file and I cannot get it to run under Mach3?
Here is a a couple of links to show you what I mean. I think its too cool and would love to try it out.
Any help here would be great.
thanks
Mark

I must try that using th 4th axis.
Full orchestral sound. Stay posted!

the gcode file is here. (made for 4 axis)

I tried running that Dasiy.ngc with Mach3 and it was nothing but errors it would not get past line 1

What we need is a midi to gcode converter! To allow us to play any midi file on our 3 axis machines!!

Anyone??

When you find a midi/gcode converter please do Stairway to Heaven first, ok?

Daisy.ngc also comes with the EMC2 download. I didn't know that it plays music though. My machine build is not quite ready to play it yet.

The Shopbot tenth anniversary video on YouTube was the first one of these that I saw. Made me want to buy a Shopbot instead of build a cheap machine.

I do now know mach to give advice. If it is erroring on line 1 - I would guess it doesn't like emc's looping/conditional/sub language.

The solution is to install EMC2...

Thaks for all your help guys,
I talk to David who made the Christmas one and here is what he said, maybe it will help us to get one running under Mach3

The math (in my case):
1 revolution is 1600 steps or Hz. 1 revolution is 6mm. 1mm/s feedrate will result in 1600/6 = 266.66Hz

The knowledge:
What frequencies are those nice notes.
http://www.phy.mtu.edu/~suits/notefreqs.html

What g code to use.
http://en.wikipedia.org/wiki/G-code

Sample:
G91 incremental mode
G01 X10 Y0 Z0 F1.65 Feedrate F1.65 mm/s for an A4 (440Hz) note.

Tricky part is the timing, X10 in the sample. The higher the note the more you need to travel to keep the same timing.

Making a formula for this shouldnt be to hard. I used trail and error.

You would make me and the rest of the world very happy of you write a MIDI to G code converter. All the info is also in the MIDI file. 2-3 UT's would do the trick.

Regards,

David
