Table instead of BUFFER...


Recommended Posts

Hello all,
   After hundred of questions, it's time to share what I think it may benefit for some people on the floor who directly use the CNC equipment.  What I found out is the "N" number is very important and how to control it.  I had this for long time but I used buffered along with the help of Colin and he had pointed a table is great for this.  For instance:

T1 first time is N1
T1 second time call out is N102
T1 third time call out is N103... and so on

Take a look at my below G-CODES and how I defined my POST.  I hope this will help some of you guys.

 

Have a great FRIDAY.....

Just so you know, in 2017 or later you can just use the tt_count$ variable or toolCount = opinfo(52, 0).  

By the way, how can I get the OPINFO number list?  I wonder how to defined the OPINFO(52,0) where does the number come from?

 

How the tt_count$ variable work?

Thank you, JEFF.D
