Haas VF-3 loop lines

[Toolfab]

So we are trying to get this control to "loop" a section of code. Were the loop starts we have the

code:

---

 M97 P(and the line #) L3 

---

and at the end we have the

code:

---

 M99 P(start of next toolpath) 

---

So the program will loop 3 times to the given spot, but after the last loop is complete, it goes to T1..wtf?

 

Anybody know the proper way to loop a Haas control?

Here take a look at my Warm program for the VF2 and see if that helps.

 

code:

Thanks Ron, I will give it a shot!

The N number is what gives each sub routine its place or name in the program. The program number goes firts where as on a Fadal the subroutine goes before the program number and is given it place or name a different way. Hope it works if not post back up and will try to help you out.

 

Also if you look at the fanuc sub program thread that macro should work on a HAAS just need to change the numbers and also take out the first part of the defintions.

toolfab...can you post that section of the program as a whole or is it too long? maybe upload the entire program to the FTP site and i'd be happy to look at it. we use m97/8 all the time.

OK, Thank you Ron. With your example and a little extra effort form the operator, (reading the manual... ) We got it to work!!!

 

Biss this is what I ended up doing...

 

code:

---

 ( .9X15 DOVETAIL TOOL - 2 DIA. OFF. - 22 LEN. - 3 DIA. - 1.5 ) 

N244 T2 M06

N245 G00 G90 G54 X-0.0255 Y0.65 S153 M03

N246 G43 H02 Z1. M08

N247 M97 P249 L4

N248 M99 P261

N249 X-0.0255 Y0.65

N250 Z0.532

N252 G01 Z0.005 F50.

N254 X-1.8456 F1.2

N256 X-1.8455 Y1.05

N257 Z0.055 F50.

N258 G00 Z1.

N259 G91 A90.

N260 G90

N261 M99

N262 M09

Now this section of code repeats 4 times then goes to the next tool. Thanks for your help!
