Fanuc OM 10,000 line limit

[wonk123]

Hi guys
I have done a search on here but can't find an answer even though I am sure it will have been bought up before.
Is there any way of going past line no 9999 on a fanuc OM, either software change or some upgrade?

I have been using Onecnc mill express and 9999 lines is a fairly big program in that, however I have just upgraded to mill proffesional, and it caused 2 major crashes on my machine. ONECNC have told me the fix is to use arc to lines and while this seems to work it makes the programs 10 times the size, one part I drew up is going to take 64 seperate programs!!

I am still pursuing ONECNC to see if there is another alternative from their end, but thought I should see if there may be another option on the controller end.

If anyone has any ideas please let me know

First, I am curious about what you are programming that needs 10,000 lines. Second, I did not know Fanuc had limits on number of blocks. I have run programs larger than would fit into memory by "drip feed" from DNC. I will have to look into this limitation more. Third, if you are faced with a problem of number of blocks, separate your programs into the sizes you wish and then create a main program that runs all of the others as subs.

Hi Mate, I am making an 8 throttle body manifold for a sports sedan with an sb2.2 chev nascar motor. The fanuc OM will only allow 9999 line numbers so obviously my posts go up by 1 not 10, the poor old girl has seriously limited memory, and I find I almost always drip feed.

I have never run anything as subroutines, but I remember doing that using basic in high school around 1981 lol I will have to look into how to do that.

My next suggestion is only put line numbers at points you wish to restart. Most of my programs are a few hundred lines with maybe 20-30 line numbers.

Check parameter 901 to see how much memory you have?

Turn of block numbering altogether. You can search for any address, such as a T#, etc., or as txcncman suggests, have your post modified to only put out N numbers at the start of each tool, or ???

As my mum used to say, "I must have only had a boy look"

O-M N9999 line limit?

Just one more answer on here for the next guy to find. I will be trying this later
I love CNCZONE

yeah, the blocks arent limited that I know of, just the 4 digit maximum 'N' value... and block numbers can be repeated (long as you arent jumping to them with a macro)

I have been running some huge programs with no problems now.

The controller didn't like no N numbers, but it was fine if every line was N1, so just changed the post processor in onecnc to step up by 0

I'm yet to see a Fanuc control that has any problem running a program with no sequence (N) numbers. Except, of course ,where they are required in the profile definition in Multi-Repetitive cycles G70 to G73, and when User Macro GOTO statements are used. Even with Multi-Repetitive cycles, only the blocks referenced by P and Q in the profile description are required to have sequence numbers.

Can you expand on the issue the control had running programs with no sequence numbers?
