Usage
First of all, download Midi23D.jar
Midi23D.jar
Run the program by clicking on it if you have a GUI, or by executing it into your terminal:
java -jar Midi23D.jar <input-file.mid> <output-file.gcode> <speed-multiplier> <tone-multiplier> <motor-test>
(Motor-test is a boolean (true/false) parameter that if it's true it plays the same notes on all the motors. It helps when you try to accord each motor speed).
Insert the parameters that asks to you.
Drag and drop the generated file into Repetier Host or your program that controls your printer.
