Custom Macro help, please

[ScottyB]

I've been writing Macro B programs for years, but now I have to go back and make some of my programs idiot proof so our company can put a flunky on our router. (Against my advice. We all know what that's like.)

Anyway, In this program I have #100 as a variable for a profile. Basically depending on the number they enter, the machine will pick up one of 4 profile heads. The problem is that in the movement body of the program I need H and D to reference the correct tool. I got an error when I tried to attach a variable to H and D (as in #149=8; H#149 for tool 8). How can I get H and D pointed at the correct tool without adding 20 lines of IF THEN ELSE statements. Below is some of the program...

IF [#100EQ201] GOTO 100

IF [#100EQ202] GOTO 200

IF [#100EQ203] GOTO 300

IF [#100EQ207] GOTO 700

IF [#100GT400] GOTO 2000 (END)

#148=[#100-200]

#149=[#100-190]

N100 S8 M03

N101 M06T1

N102 GOTO 1000

N200 S8 M03

N201 M06T2

N202 GOTO 1000

N300 S8 M03

N301 M06T3

N302 GOTO 1000

N700 S8 M03

N701 M06T7

N702 GOTO 1000

N1000 #105=#101+3.00

G90 G0 X#105 Y#102

G90 G0 G61 G43 H#148 Z1.

G90 G1 Z-.400 F100.

G91 G0 G42 D#149 X-2.00

G91 G1 X-1.00 F200.

X-#101

Y-#102

X#101

Y#102

 

Thanks,

are you sure the value of your variable is valid when you read it ?

[ScottyB]

Yes, in this case H=1 and D=11. The controller seams to use 1 as the H value instead of the offset value that's in 1 (-4.622 for example).

Do you think this should work?

 

BTW Fanuc OM controller with Macro B.

Scotty,

Can you use #999 (spindle tool #) as a varible? IE,

T1M06;

...

G43H#999Z.1;

G41D#999XY;

 

 

This works for us. Fanuc contol.

Try this

 

IF [#100GT400] GOTO 2000 (END)

#148=[#100-200]

#149=[#100-190]

N100 S8 M03

N101 M06T#148

N1000 #105=#101+3.00

G90 G0 X#105 Y#102

G90 G0 G61 G43 H#148 Z1.

G90 G1 Z-.400 F100.

G91 G0 G42 D#149 X-2.00

G91 G1 X-1.00 F200.

X-#101

Y-#102

X#101

Y#102

 

It looks like you were skipping

#148=[#100-200]

#149=[#100-190]

with your goto s'

[cam-eleon]

Looks like if all IF statements fail then this is the only time #148 and #149 will be assigned.

Move the assignments down to after all the jumping is done. Just my WAG(wild a** guess)

H[#[148]]

[ScottyB]

MY BAD!!!

You're right.

My GOTO's were jumping over my variables.

I made the changes and everything works.

 

ScottyB. grammin Gcode longhand for the next few days.

 

Ever try to figure out a program that you wrote 6 years ago?

 

WTF was I thinking?????????
