Revised MIDI to Gcode conversion script - much improved!

[Mike]

Hi folks
This may appear twice, but my previous attempt from last night hasn't
yet hit the list...

I've been working on the mid2cnc.py script to convert MIDI files to
playable gcode.
I've extended the script to work for arbitrary machines and predefined
a few more popular ones.
Also it has a beefed-up command line parser so most options don't
require script changes.

Please take a look at the GIthub repository here:
https://github.com/michthom/MIDI-to-CNC

It has sane defaults for use with a Makerbot Cupcake, so folks on this
list can mostly just run:
./mid2cnc.py

This assumes:
Input file: ./midi_files/input.mid
Output file: ./gcode_files/output.gcode
Machine type: Makerbot Cupcake CNC 3D Printer
MIDI channels: 0-15 inclusive
Play on: X, Y, Z axes

For the more adventurous, here is the new usage block:
usage: mid2cnc.py [-h] [-infile [INFILE]] [-channels N [N ...]]
[-outfile [OUTFILE]]
[-machine
{cupcake,custom,shapercube,thingomatic,ultimaker}]
[-units {imperial,metric}] [-ppu XXX.XX YYY.YY
ZZZ.ZZ]
[-safemin XXX.XX YYY.YY ZZZ.ZZ]
[-safemax XXX.XX YYY.YY ZZZ.ZZ] [-prefix [PRE_FILE]]
[-postfix [POST_FILE]] [-axes XYZ] [-verbose]

Cheers

I just uploaded a couple of sample output files to the Makerbot music
