As we begin 2021, we have found ourselves in a situation where our lead-times have substantially increased due to COVID-19 pandemic-related issues.
Those issues combined with high demand and heavy shipping volume is resulting in a longer than normal delivery timeframes for many Tormach machines and accessories.
We are working diligently to resolve these issues and look forward to bringing our lead-times back to normal. Unfortunately, this is going to take some time.
As of now, we anticipate that these lead times will continue into the second quarter. We appreciate your patience during this time.

ABOUT G-CODE PROGRAMMING LANGUAGE

A G-code program is made up of one or more lines of code. Each line of code is called a block, and can include commands to the machine. Blocks are collected into a file, which makes a program.

A block is normally made up of an optional line number at the beginning, followed by one or more words, which groups the elements together into a single statement.

A word is a letter followed by a number (or, something that evaluates to a number). A word can either give a command or provide an argument to a command.

A program is one or more blocks, each separated by a line break. Blocks in a program are executed either:

  • Sequentially (from the top of the program to the bottom)
  • Until an end command (M02 or M30) is encountered
EXAMPLE: G01 X3 is a valid line of code with two words: G01 is a command: the machine should move in a straight line at the programmed feed rate. X3 provides an argument value: the value of X should be 3 at the end of the move.

Most commands start with either G (general) or M (miscellaneous) — G-codes and M-codes.

There are two commands (M02 and M30) that end a program. A program can end before the end of a file. If there are lines in a file after the end of a program, they’re not meant to be executed in the normal flow (they’re generally parts of subroutines).

You can add comments or messages to lines of G-code to help clarify the intention of the programmer: to embed a comment in a line, use parentheses; to add a comment to the end of a line, use a semicolon.

 NOTE: The semicolon is not treated as the start of a comment when it’s enclosed in parentheses.

Comments can appear between words, but they can’t be between words and their corresponding parameter.

EXAMPLE: S100 (set speed) F200 (feed) is okay, but S (speed) 100F (feed) is not.

If the comment occurs on a line with M00 or M01, and contains a file name with a .jpg or .png extension, PathPilot displays the image in the Tool Path display when the program reaches the M00 or M01 break.
