    A midi file that you want to play on your CNC eh...
    I have been programming in C & VB for years, a quick look at the python code makes me think of C. I guess my question is why would you want to do this?

    Thank You.

    Because people with CNC machines are natural born geeks?

    Because I'm a geek. It isn't enough to know how, but also to know why.

    Most of the work is done by Python and the mid2cnc.py script. If I get the syntax of the command correct the script file should spit out a filename.gcode text file. I already know that Mach3 can load and run it if I rename it to filename.txt.

    I'll keep looking for more info. All it takes is one missing, out of place, or wrong character and the Python command parser gives a syntax error.

    Update: The file is set up for 2000 pulses per inch, and my machine is 4000 ppi, so, it plays but doesn't run at the correct speed.
    Try setting your FRO to 50%

    I have three files that came from the site that provided the mid2cnc.py converter script. Those files are running very slow. Slowing them down isn't going to help. FRO does change it though. I need to increase the PPI setting in the gcode to match my hardware PPI setting.

    The three midi files that the gcode was created from are also included in the .zip download. Those three files don't run with a midi file player. Not good. Wasting my time messing with those and the gcode files that were made from them. The guy that made the three gcode files says they have not been tested.

    I do have a good midi file that I'm trying to convert to gcode. It plays for 8 minutes from a 57kb .mid file in Windows Media Player. I think the Readme file for the mid2CNC script has some incorrect information.

    The Python GUI for Windows has a command line parser that highlights a syntax error in red. The regular Python command line interface has no apparent editing and copy/paste functions. Making any change to the command line entry means typing the whole entry over again. It's possible that the GUI is not working right. Oh well, no guarantees.

    Many thanks Chuck!!

    Homeconstructor - Converter: music → G-code

    Boy was that method easy to use. That got me the Stairway to Heaven conversion that I was trying to create. It plays great for a little over 8 minutes. (86kb)

    Only problem is that my X/A axis lead screws resonate at some frequencies and need dampeners at certain locations outside the operating range of the movements. Holding those places quiets the resonances.

    The FRO will go above 100% and that speeds it up enough for the slow files to sound right. Thanks.

    Well, I finally updated my 'alignment/clamping' setup. Drilled a pine board so it's held down on the far side as my edge to always go up against, put some brass threaded things near the x0, and drilled a board for that, held down by nylon bolts. that makes my little 'l' shape to reference everything off of. Also made some of those cam clamps. Seems to work quite well. I now realize it would be better to have some sort of bushing in there so it is washer to bearing to washer compression to hold it in place and let the cam clamps rotate freely. But it works, I'll figure all that out later.

    Here is a shot of the 'back' of my pine celtic box... just a teaser.

    And I re-drew some other wood clamps to fit my 5/16 bolts... crv file attached for anyone interested. Figure can't hurt to have different types available in case they are needed.

    Oh, forgot that I have a question... When using that minwax poly, how do you get a smooth finish? Using a foam brush... looked around the internet, some say you need to thin it (with something), some say sand when cured, then polish with rubbing compound and such just like a car.

    I'd brush on one or two coats, sand with 320-400grit, remove ALL TRACES of dust, and use a spray can for the final coat.
    It's very hard to keep specs of dust out when brushing.
