Macro Help

[GoetzInd]

Hey Guys,

I am writing a backup tool macro for our machines that don't have built in tool management. What I am trying to do is ad an H variable that will re-run a certain part of a program (Defined line number) after a tool has been checked broken and replaced. My question is, how can I loop back into the main program using a GOTOn command in the macro? Is it possible? Thanks,

for any suggestions.

It's been a while but don't you just need an M99? Or are you trying to loop back to a specific spot in the main program?

Exactly. I want to re-machine the feature where the tool was deemed broken.

I don't think a GOTO statement will work. I'm not sure if what you want to do is possible. Sorry I couldn't be more help.

want to make sure i undererstand, you want to call a program thru m98 or m198, and have it restart at a specific seq number?

You can't use a GOTO with a destination outside of the program the GOTO is in. What you can do is set a variable that indicates a broken tool, was detected and then use that variable back in your main program do make a decision. IE

 

Inside broken tool detection macro at the end

[iF **** NE $] GOTO1000 (**** NE $ = the system variable for broken tool, this will vary by MTB)
#100=1
N1000 
M99

 

 

Inside main part program where you call your broken tool detection macro

G65 P98**  (BROKEN TOOL CHECK MACRO)
[iF #100 EQ 1] GOTO[#****] (GOTO ****  = variable of tool in spindle to go to tool change line so it changes to replacement tool)

That's already the direction I figured I'd have to go. I was trying to avoid any change to existing programs but it's not a big deal. Thanks guys.

M99 with an H? I remember using that on Mazaks...

 

M99H100(return to N100 in main prog) Or associate a variable? M99H#100

[GoetzInd]

M99 with an H? I remember using that on Mazaks...

 

I don't think so but it's worth a shot.

If you are just trying to jump to a specific location, try M99 P###, where ### is the "N" number to jump to.

 

I re-read you post, what I described above would only work from the same program. What you could do, in your subprogram if an error is detected, set a flag in a local variable, then test the flag in your main program and jump accordingly

[specv]

here is what I have done in the past, at the end of each tool, before I do a broken tool check, I write to a macro number:

Example:

 

N100T1 M6

CODE

'

'

'

'

'

'

#600=100

(BROKEN TOOL CHECK)

 

At the beginning of the sub have a goto statement: goto#600

that way when a tool is broken it will go to the tool that just ran.

At the end of the sub write #600=1 so that when it goes into the sub it will start at the top of the program.

 

If a tool comes up mulitple times this can be benificial because you can specify which instance of the tool broke.
