How to use subprograms on a CNC

[@gabriel.sampaio]

Loved the video. Gretings from Brazil. Keep up the good work

Nice sub demo. Great information Thanks

i came for the sub program tutoriel, i stayed for the "oh and by the way, this is how i cheat to turn parts on my mill" 0.o love the vid thank you so much!

Very clever, thanks for sharing.

[@bluddywulf6796]

You could have done that with 1 sub using incremental in the sub and call out your start positions at each point in the main with absolute,If you are using the same tool path.

Awesome video, thanks.

My God. You're genius bro

[@kittadyne]

Thanks, I occasionally agree with that 😄👍

This is pretty neat! I'm in trade school for programming and machining, hope i can become this skilled some day

[@kittadyne]

Have fun with school, enjoying yourself is the best way to learn!

I made a bar puller sub program (O12345) and I want to run 10 parts on my lathe then stop. For some reason it runs continuously and doesn’t stop. I start the main program and before I do any machining I call up the bar puller sub. Then at the bottom of my bar puller sub is an M99. Also at the bottom of my main program is an M99. When I call up my sub, when I input M98 P12345 L10…it runs the bar puller sub 10 times before it starts machining the part. How do I get it to run the sub and main 10 times then stop? What am I doing wrong? Are my M Codes in the wrong place? Or is my Haas lathe too old? It recognizes the L…but where do I put it to run the puller then main a certain amount of times? I thought the only M98 is for the sub.

[@kittadyne]

From what you described my 1st thought is the Loop command [ L10 ] should be in the main program, no loop in the sub. 2nd thought to tell you to look at the difference between M99 & M30 or M2 at the end of a program. Post your main & your sub programs in the comments & we'll look at it.

[@F30586]

@@kittadyne the L10 is in the main. At the top of the program…before it calls the first tool. So it reads the safety blocks…then I call the sub up M98 P12345 L10…then it runs the bar puller sub (O12345) and at the bottom of that sub is the M99. So then it jumps back to the main and runs the main program. And at the bottom of the main is an M99 as well. So with the L value in that block with the sub call…it runs that sub 10 times before running the main. Should I put the Sub Call block at the end of my main rather than at the beginning?

[@F30586]

So I’m trying to get it to run only a certain number of cycles and then stop. Which is controlled by the L value. I’m thinking I have the codes in the wrong spot. I have an M99 at the end of both programs. It’s a Haas lathe. Late 90’s model.
