I forgot to tell you about the setup steps, but I'll describe them here. The motor pitch is 20 steps per revolution, the propeller pitch is 3 mm, so 20 divided by 3 equals 6.666666666666667 steps per mm. However, I used drivers with a microstep of 32, so 6.6666666666666667 multiplied by 32 equals a rounded figure of 213.333 steps per mm. This can be seen in the Grbl controller console video at 19:55. It says X, Y, and Z, and you should set the value to thousandths.
Also, don't forget to put all the include clauses in the firmware in quotation marks, as in the video at 18:37, otherwise the sketch won't compile.
