Centroid Community CNC Support Forum

I have been working with ‘g-code comments’ using the convention in the centroid m-series operators manual that uses “colons” and “semicolons” to denote comments in a g-code program. Both the Peter Smid CNC programming Handbook and Machinery’s Handbook (page 1229) indicate the usage of Parentheses before and after the comment. I thought that use of parentheses for comments was an industry standard. Why is the method used by Centroid different.


steve

you can use either.. try it:-)

";" and "(" both let cnc12 know that everything to the right is a comment

Will it also work with a right parentheses ")"

; this is a test
(this is a test)
G1 x3 f40 ; this is a test
G1 x3 f40 (this is a test)

are all valid g code comments.
