Spindle

The spindle is the part that holds the milling bit. It's connected to a DC brushess motor that can turn as fast as 14000 rpm.

It accept 1/8“ bits (3 to 3,5mm)

You can control it in the “Jog” panel with those commands:

  1. M3 S Turn on spindle on clockwise
  2. M5 Turn off spindle
  3. M4 S Turn on spindle on counterclockwise

Example:

  • M3 S13000

You can decide how fast the motor turn with this command:

M3 S where can vary between 7000 to 14000 rpm (if you use a value lower than 7000 the spindle will not start).

Use M3 command for standard mills (that are the most used), and M4 for counterclockwise mills (used just for special uses).
