I am at a total loss as to what the proper syntax and structure is for Mach 3. Can anyone help with this simple loop?
Another question, is there a PDF or tutorial some where that documents all the loops and how to properly code them? I am also looking for a good book. I have seen the reccomendations on CNC by peter smid. It sounds good but does it cover the mach 3 flavor of G-code? I talked to several people where I worked about my problem and they said it all depends on what controlled you are using. They work in 2-3 different ones and they siad that they are similar but very different also.


Graham, your reply to Riddler was helpful, but his question about Mach3 g code version vs Smid slipped by. I'm searching for the same. (I posted earlier today) Your reply to Fastest1 (Subroutine confusion, Oct 02, 2010) was great, but maybe a compilation of all the great basic explanations would save hours of noobie search time. :)

Look at this link, They are many PDF files you can download.

You can also ask for a printed copy of the Mach3 Manual.

sorry, but I don't see a link here. :)

Where can I find a tutorial of Mach3 version g code beyond just the quick reference available from the button on the Mach3 screen?   Many of the posts here are helpful, but assume a prior knowledge of the basics (i.e. of syntax and allowable commands for subroutines) which I don't have.  My old brain protests trying to piece together and draw inferences from scattered bits of information. there must be something, somewhere, laying out the groundrules for crusty noobies. :D  thanks

Ahh, relief.  for the immediate facing problem, I came across the entry in "Share your Gcode" Multi pass facing program. Thank you.  Still looking for the more complete documentation for Mach3 gcode.

I know - that's what I have ended up doing. VBS does at least support sensible language features.

 This is my first post, still putting together my CNC router and exploring Mach3,  also have hit the wall on conditional Gcode problem. I have very little programming practice, but enough to be dangerous.  I am searching for an entry level tutorial on Mach3 version of Gcode. could you please elaborate on your creativity?  I'm trying to make a "quick" program to mill (true the face of) the sacrificial board over the entire working area.  Somewhere on this forum (Gcode thread, I think) someone referenced  NIST RS274 NGC standard for Gcode. I read that and pieced together a short subroutine, tried to run in Mach and was stalled by numerous errors (my code seemed to conform to the standard). Where is the documentation in Mach that reveals all the exceptions to NIST RS274?  Perhaps there is a better thread to post my questions ?
