Okuma buffer overflow

[RDEMIDON]

I am having an error with my Okuma MX45. I have a program thats in the memory, but when I try to pull it up in the "buffer memory" (to run it) I get a buffer overflow error. There is more than enough memory in the mach. (500k) and the program is only 40k. If I shorten the program up to 38k it fits. Is there a way to expand the buffer memory, or at least view its size? Thanks, Ryan.

I think the only solution is to spend lots of money for memory upgrade.

Or something like the DNC-B or DNC-DT option.

You might be able to "trick" it and host the file in the MD0: directory.

[RDEMIDON]

The program is currently in the MD1: directory but I can't load it into the memory to run the program.

[jeff]

I'm assuming that you don't have the DNC option on that mill, so your only other option is to split the program into 2 seperate programs and run it as a schedule program.

Schedule programming is a pain to figure out at first, but it is a handy feature.

load it and run it in B-MTD

 

this will skip the buffer and read the NC directly from the MD1:

 

positive point , you will be able to run 500K program without problem

 

the negative point , you won't be able to edit the G-code on the machine

[Greg Williams]

You can expand the buffer memory by allocation more space to it. I would run the program in method-S or method-B

[RDEMIDON]

Goldorak,

How do you run it from the B-MTD?

 

And Greg,

How do you run method-S or method-B? Are they programs in the machine?

 

Thanks.

RDEMIDON tell us what is the controller , beacuse they handle the buffer differently from one version to an other

 

on our U-100M it's a box in the program select page to switch from A, B and S method

It is the same on the E and P series. It has been a long time since I have seen a 7000 or a 5000 sries I will need to find an old manual to check those

 

Being an MX it will probably have a U series or a 7000 control

[RDEMIDON]

The control is a OSP700M. What does each one (A, B, and S) do?

[Greg Williams]

From the Programming Manual

 

• When A-Mtd is selected

Program running method A becomes effective.

The program to be executed is transferred to the operation buffer in batch.

This method is used when the program is smaller than the operation buffer capacity.

• When B-Mtd is selected

Program running method B becomes effective.

The program to be executed is called to the operation buffer in several segments.

This method is used when the program is larger than the operation buffer capacity.

Since schedule programs, subprograms, and library programs are generally called to the

operation buffer in batch, these programs must be created with restriction placed on their

capacities.

• When S-Mtd is selected

Program running method S becomes effective.

This method is used to execute a large program which does not use branch or subprogram

call functions.

[Greg Williams]

You can also add it to your Schedule programs

 

PSELECT TEST1.MIN ;B

PSELECT TEST2.MIN ;S

PSELECT TEST3.NIN ;A

END

there is the way to select operations methods for 500 and 700 controls

 

in the NC optional parameter (word) No:11

set at "0" is A method

program executed entirely from the buffer

 

set at "1" is B-method

program is executed in segments from the memory but you can still use sub programs

 

set at "2" is S method

this is a line by line method , no GOTO and sub program allowed

[RDEMIDON]

Do you happen to know where the selection box is on the OSP7000M control? I couldn't find it under the program select option.

[RDEMIDON]

Sorry just read your last post. Will try it now.

[RDEMIDON]

That worked. Thanks so much to everyone that helped.

[Goldorak]

no prob

okuma nooob, here.

 

osp 7000L. macturn30

i went to NC optional parameter (word) No:11 and there was a "50" there./?

NC optional parameter long word No:11 was at 0, but setting it to 1 still resulted in buffer overflow when selecting program from MD1:

 

77k main

62k *.ssb subprogram (57k works)

[mkd]

L controls don't have these functions nevermind.
