Using o-words with PlanetCNC TNG software

With PlanetCNC TNG it is possible to control g-code program flow. For this purpose you can use o-word g-codes.

o-words are formed as blocks and can be, based on their functionality, categorized into 4 groups:

(subroutine block)


(do…while, ehile..endwhile loop block)

(repeat…endrepeat block)


During this multipart tutorial series we will try to explain the use and behaviour of each particular O-word group.

To understand the working principles and behaviour of a different o-word block we would recommend that user first gets
familliar with the PRINT command.
