Hmm. Networked CNC orchestra, synced to internet time. Stereo?:violin:

There is some info on Tim's site on how he did it.

Nice choice of songs. I hope he makes the 'mid2cnc.py' available.

Years ago in school the IBM tech had the line printer play the marines hymn. It was printing out garbage at an incredible rate though.

Try this from my gallery.

That's it.
Forget tooling, offsets, dust collection and making that laser. I'm just going to write CNC music!

I just recorded and enhanced a stereo path/song days before I came across this thread.

I write midi, play actual instruments, have a small home studio, but who knew my home built CNC tool could be my new instrument?

oh boy oh boy...

You can skip the first minute of this video, the song starts a little over a minute into the video.

Hi guys,

I tried to run thoose starwars files on my cnc but no music was played... =(

I have a homemade L297 unipolar chopper driver, do you know if it works with that? I use a 2mm leadscrew, with 200 steps motors runing on half step so 400 steps per rev.

On mach3, my motor tuning setup is on 200 pulse per mm

What do I have to do? Or maybe it just doesnt work with my drivers...

Thanks

[ryanhathy]

Brenck,

The Star Wars g-code is in inches and designed for a machine set up for 40,000 steps per inch. That's 1,574.8 steps per mm. You should be able to change your motor tuning to match that, then use the G20 & G21 codes as neilw20 has said to run the inch g-code on a metric machine.

neilw20 said:
"Put a G20 at the start of the program and a G21 at the end."

Basically, since you are running the g-code on your machine without any conversion, the numbers are about 1/200 what they should be. The frequency would be far too low if the motors are even stepping since the numbers equate to about zero in the metric world.

Let me know if you get it working.

Thanks a lot Ryan,

It works great, my brother freaked out!!! He is a big stawars fan

[vlmarshall]

Great work, Ryan! Awesome choice of music in that video. I've been thinking for a while that anything written for the pipes would sound nearly perfect on steppers.
Thanks for sharing that one.

[ryanhathy]

I agree, bag pipes are probably the best match.

My kids love it when I play music for them on the CNC machine, especially star wars. I wanted to share what I've done so everyone can share those kind of moments with someone. I'm uploading the g-code for Rocky Road to Dublin along with a MIDI file of the song and an excel spreadsheet of the calculations. I kind of have my own system as far as the calculations go on the spreadsheet, so I'm not sure it would be very easy to understand if you're not a part of my imagination, but I think this is the easiest spreadsheet to use so far. The first songs I did that were pretty short probably took longer than this one to transcribe. As I've said previously, I have a setup just for playing music with all the axis set the same at 40,000 steps per inch, 1,574.8 steps per mm for you metricans. And don't forget to add G20 and G21 as mentioned in post #54 to convert to metric.

If anyone tries it, please let me know how it turns out.

[vlmarshall]

Nice, thank you for posting this one! :cheers:

I don't have my 4th-axis hooked up at the moment, don't have a way to open Excel files, and my steps per inch are around 32,000...but it's still really nice to hear. Tweaking the feedrate override brings it closer to being in tune.

I could REALLY get into converting pipe tunes... the 4th-axis would work great for one of the drones, since it won't run out of travel playing the same non-stop note...
There are tons of pipe tunes in .MIDI format... but they all stumble a bit over gracenotes...I wonder if it would be possible to convert the .bmw and .bww files of the Bagpipe Player utility...ah, to dream.
