It can be helpful if the g-code jumps around. ![]() Sometimes we don’t want to just keep executing g-code one block after the other from top to bottom. So far, we’ve learned how to parameterize g-code with variables and expressions and how to package it into building blocks using subprogram and macro calls, but these three simple concepts of GOTO, IF, and WHILE, will boost the power of g-code even further. – WHILE: The ability for G-Code to perform repetitive tasks. – IF: The ability to make decisions based on Conditions. – GOTO: The ability to jump around arbitrarily in G-Code. This installment of our Mini-Tutorial on G-Code Macros is all about three important constructs in G-Code Macro Programming: CNCCookbook’s G-Code Tutorial Introduction to Conditions and Looping
