The ProtoTRAK is mainly conversational, but it uses standard M-codes for the spindle, tool change, coolant, and program stops. Here are the common ones and what they do.
A 4K M-code wallpaper keeps the common machine codes on screen all day. Here is what to include, how to design one that stays readable, and its one real limit.
A wall poster of the common G and M codes is a great quick reference. Here is what to put on it, how to format it to read from a few feet, and its one real limit.
G-codes control how the machine moves and M-codes control machine actions like the spindle and coolant. Here is the real difference and how they work together.
The core M-codes are identical on lathes and mills, so learn them once. The real difference to remember is the tool change: M06 on a mill, the T word on a lathe.
M09 turns the coolant off, closing the M07 mist and M08 flood pair. Here is the family pattern that makes it stick, plus the drill that ends the forgetting.
M06 executes a tool change while the T word selects the tool. Here is how T6 M06 works, the safe sequence around it, and why G43 always follows.
There is no universal M-code that fires a plasma torch. Different controllers map it differently, often to M03 or a custom code. Here is why, and how to check.
M03 starts the spindle clockwise, M04 starts it counterclockwise, and M05 stops it. Here is what each does and how to remember the set.
A short reference of the M-codes you will meet first: spindle, coolant, tool change, and program control, each with a plain-language meaning.
