G-Code letters What are the definitions?

[CADkathy]

I am currently setting up a machine and having problems. I am looking at the G-code after posting, how do I find the definitions of each of the letter codes? Example what is SP,SF and PA? Is there a place to find these definitions?

SP,SF and PA could be your problem. Most G code programming is one letter followed by a numeric value.

Example:

N010 M03 S300

N010=block number
M03=spindle forward misc. function
S300=spindle speed of 300

Hi CADkathy,

here is a link to general G-code definitions... http://www.linuxcnc.org/handbook/gcode/g-code.html

As I understand it, SP,Sf or PA are NOT standard RS274D G-code.

Hope this helps... a bit

It might help to identify what control you are using. Some of the PC based or other controls may have unique designations.

What is your CAD program? What is your machine control? If you have a programming manual for the machine, it will tell you all you need to know. Otherwise give some more info here and you'll get the help you need.

Complete G-Code reference from the people that had a bit of a hand in designing it. NIST...

With the information y'all (Yes it has been a long time since I moved South) sent, I was able to contact my software provider and determine the post processor the machine manufacturer suggested I use was incorrect. I am now using another post and my machine is cruising.

Thanks again!

Kathy,
Just for the record, SP and SF and PA represent "Select Pen" / "Set Force" / "Plot Absolute" in Hewlett-Packard's proprietary 2D pen-plotter language HP-GL. They are adopted also into certain versions of RML and CAMM-GL used with Roland 3D micro-mills.
