c9k

[So not a Guru]

Almost every post I work with has these constants

c9d         : 999   #Define constantc9k         : 9999  #Define constant

What are they generally used for?

ck9 is a value used to emtpy a variable with a value that should not match anything else....

 

kind of a fail safe for calculations

Ok, I can see how that could be pretty handy in a lot of situations.

Thanks John

What if I wanted to use or my feed was auto-calculated to 9999?

 

Magic numbers are bad

That's awful fast feed.  In all of my macros and everything I calculate in I have safe numbers as my UH-OH variables.  That way, just in case, feeds come out "safe."

Could these values also affect drill cycle clearance planes? When translating/transforming drill toolpaths I would get z9999. and R9999. values in the translated drill cycles. Just curious, as that c9k value looks like it may be affecting it.

Change c9k to something unique and post again. You should confirm it, or not.

Makes sense. Changed c9k to a different value and it did not affect the translated cycle, still posted out R9999. Another topic suggested that it could just be a bug with translated cycles. Thanks.

c9k was commonly used to set the previous value of a variable, essentially forcing it out the next time the variable is encountered.  We have had the "force" function for many years that is a much better way of handling this.

 

 

for example both of these will essentially force the feedrate output the next time it is encountered in the post.

prv_feed = c9k

 

result = force(feed, feed)

Frank I looked at the file and the post and it was a binned post with a question that was asking for clearance moves. That was interfering with the transform operations using coordinate when we went back to tool planes the 9999 went away, it lead me to believe it was a post issue and issue more than a Mastercam bug.

Not in metric.
