GOTO jump instruction

[maximusek]

Hi

In Nakamura TW-10 with controller Fanuc 18T I'm not able to jump over the block of the program GOTO10, GOTO#10 (as book says) gives me back alarm message 004 adress not found. I'm sure there is block N10 in my program. Any clue?? Thank You for any advise

GOTO10 would be correct
GOTO#10 will not work
It can only jump to a line number, not a varible number. You will need to have macros enabled on your control to use GOTO command.

But this should work just fine.

#10 = 10
GOTO#10 
.

.
N10 ...

I dont think you can assign varibles to line numbers.

The correct syntax for MY Fanuc is GOTO10

Sometimes you can use

M99P10

Instead of the GOTO statement

Does the same thing, unless its from a sub, then it would return to the main program looking for an N10

Thank U Guys, I think "You have to enable macros in your machine" is correct :-); In my swiss simple GOTO10 works without any problem, GOTO#10 is taken from Fanuc Programing Manual. Now I have to figure out how to check "macros enabling" in my TW-10, heh I love this job...:-)

for all

"GOTO#10 is taken from Fanuc Programing Manual"... Ive never seen such a example, but to check if you have macro option just MDI #1=1 If it alarms out, you dont have the option my friend If you do have macro option, then GOTO10 should work just fine

It has been a while since I used it and now that I think of it some controls may want the variable in []. I have used this type of program on both Mit and Fanuc controls.
GOTO[#10]


It is just like when you use a variable in a gcode word like the code below.
Set #3 to 0 and the path goes around counter clockwise, set it to 1 and the path goes around clockwise. You can do this type of thing when you want to mirror the cut but still climb mill on both mirrored and non mirrored parts.

#3=1  (0 COUNTER CLOCKWISE, 1 CLOCKWISE)

G0X0Y0
G1G[41+#3] X1.000 D1 F20.0
G1 Y[-0.750*[[#3*2]-1]]
G[3-#3] X0.750 Y[-1.000*[[#3*2]-1]] R0.250
G1 X-0.750
G[3-#3] X-1.000 Y[-0.750*[[#3*2]-1]] R0.250
G1 Y[0.750*[[#3*2]-1]]
G[3-#3] X-0.750 Y[1.000*[[#3*2]-1]] R0.250
G1 X0.750
G[3-#3] X1.000 Y[0.750*[[#3*2]-1]] R0.250
G1 Y0.000
G1G40 X0 Y0

Because I don't like to be a liar :-) Fanuc 16Tc-18Tc Operators Manual - chapter 16 Custom Macro - 16.5.1 Unconditional Branch (GOTO Statement) page 290. It wasn't Programming Manual though - sorry

Thank You for second part of your post...

maximusek,
I wasn't calling you a liar! and your right its in my macro section as well...so i'm the liar! It doesnt give a example how to use this GOTO#10
I will have to check this out today. I've never seen such a thing??? learn something new all the time. Did you find out if you have macros?

%
#10=1;
GOTO#10;
;
;
N2;
N1;
M30;
%
Okay, this does work. My apolgies to everyone involved in this thread. I learned macros on Allen/Bradley contols and this doesn't work there. I learn new stuff all the time. Which is why I like to program macros in the first place. I think what I was thinking was this...N#10. That would not work.(or would it??? )

jamesweed,

I know You didn't call me liar, maybe I should answer different way, I apologize. The reason I asked about is: making program is one thing but setup is another. Many times I have to compromise cycle time and f.ex. good surface finish or tool life. It is very usefull to jump over the part of the program using just GOTO (next block) to change the order of operations etc.etc. When First Part Raport is done and spindles are still in the same place I clean everything to prepare final version to back it up, but during setup, program looks like war zone :-). I was very suprise when in my swiss GOTO100 works ok and in tw-10 Nakamura not. Maybe tomorrow I'll check it out, interface looks like MS-DOS, I suspect I don't have macros enabled. That lathe is the oldest machine we have. That may be a problem. Anyway thank You Guys for help- jamesweed, Andre'B, beege -
