S (spindle) command 10k and above

[Bruce Griffing]

I am posting to Fanuc and I cannot get S commands above S9999. My spindle goes to 13k. How to deal with this??

Hello Bruce,

In CAM goto Edit > Post processor and open the post your are using.

Next, goto File > Save As.. and give this post a new name, so that the original can't be overwritten by mistake and any edits can be discarded.

Next, scroll down until you see the section WORDS: you will see any entry similar to this

:SPIN = {"S"DDDD}

This sets the spindle speed output to a maximum of 4 digits, change this to read :-

:SPIN = {"S"DDDDD}

This will allow 5 digits that will give a maximum of 99999, you could of course set this to :- :SPIN = {"S"DDDDDDD} for a maximum of 9999999

Then save this new post and select this when you next post-process.

Sorry, just noticed the first line "YOUR" - what an idiot I am. Should have been "you're"
