Sin840D problem with loop

Hello,
I have problem with loop in sinumerik840d.
Bellow you wiil see block of NC program.
Loop begins with word VYPOCET1 and to return we use command GOTOB.
I dont know how to define it to work correct.
Under command GOTOB I use macro Siemens840DGoto with value -1.

N8210 VYPOCET1:   
N8220 R2=360/8 ;=========uprav
N8230 R6=R1*R2

N8240 G95
N8250 H74=76
N8260 G0 B1=90. C4=0.0+R6
N8270 H74=75
N8280 TRAFOOF
N8290 G54
N8300 D1
N8310 CUT2DF
N8320 M154
N8330 M150

N8340 G19 G0 X-1. Y-10.071 Z16.748 S1=5000 D1 M1=3
N8350 G1 X-1. F.16
N8360 G42 G1 Y-1.335 Z6.9 F.08
N8370 Z-1.1
N8380 Y-8.335
N8390 Y-13.777
N8400 G2 X-1. Y-17.452 Z-.325 CR=9.1
N8410 G1 Y-20.474
N8420 Y-27.474
N8430 Z7.675
N8440 G40
N8450 Y-18.737 Z17.523

N8460 DIAMOF
N8470 M96
N8480 R1=R1+1
N8490 IF R1<8 GOTOB VYPOCET1

Thanks for your help

Re: Sin840D problem with loop

Have you tried to run this small piece of code using the latest Sinumerik CTL from the samples library?

If you didn´t, I´d suggest you to do so and then enable the debug mode to see how your program is interpreted by the latest CTL from the library and then compare against your current CTL.

That would help you to narrow down which macros are being used and how they´re being called.

The Sinumerik 840D CTL shipped with VERICUT is constantly enhanced and if your CTL was based in an older version there´s a significant chance some functionality is wrongly defined in your CTL.

Re: Sin840D problem with loop

Thanks for your reply...
I tried latest version 8.1.1 but with the same result.

I can´t define this word VYPOCET becouse it can be diferrent in next NC program or can be there more loops.
Commad GOTOB wont accept this word VYPOCET to skip there.
It works corret only if I subscribe the word with row number. But its not best solution.

Re: Sin840D problem with loop

Thats exactly why I never use the LABEL: GOTB LABEL format, unless this label has a fixed name.

Better is to use the WHILE - ENDWHILE

N8210 WHILE R1<8   
N8220 R2=360/8 ;=========uprav
STOPRE ;Be sure to add some stopre's to be safe when nc is read ahead, See Sinumerik manual
N8230 R6=R1*R2
...
N8460 DIAMOF
N8470 M96
N8480 R1=R1+1
STOPRE
N8490 ENDWHILE

of use the FOR - ENDFOR format

N8210 FOR R1=1 TO 8 ;Not sure, but I think R1 counts up automatically because of the FOR ... TO ... statement
N8220    G0 XYZ
...
N8480    STOPRE
N8490 ENDFOR
