Hi Guys, I am using a KRC2 controller for milling operations, creating large size parts and the program line numbers ideally would be around 50-60.000. The problem is that KRC2 does not understand a program over 30.000 line programs. Do you have any idea where the max number of line is set? What is the way tune it up, in which folder whic file can I change it? Thanks in advance

Hi racecarteam,
I am guessing that you are making a lot of positioning instruction?!
I wonder if it is not possible to make some mathematical calculation instead??
Ore maeby you can do some sectioning - call of subroutines?
Best regards

Writing the tool path with a software and the post processor creates the file which has number of lines sometimes over 30.000. Now I break the milling into smaller sections and it helps... But would be lot better to find in ghe KRC2 software where can I rewrite the magic 30.000 ie for 70.000 and go fishing until the robot works...

As far as I know the upper bound is not defined by a special value, but depends on the available memory. Hence to get more space you will ned to increase your systems VxWorks memory.

Sorry to look sily, but you mean increase RAM of the robot's computer? Or explain please.

Understand now, looked it up. So I need to buy a bigger VxWorks memory? Can you please go into details? Many thanks!

I think that won't help.
There is a limitation for the maximum file size of one file (about 64k in the memory). The same issue with the .DAT files.
Increasing the memory therefore doesn't help. The only thing You can do is what You already do: split the files.
By the way. Increasing the memory can only help if You have too much files. So that the sum of all files be more than the available memory.
And You have to change settings in the registry to change the available memory. There also is a limit which is not that much higher than the standard value.
The KRC2 can be hacked somehow (I mean modify the relevant part of thr software) to accomodate larger program files? Presently the max allowed program line numbers are 30.000 and the file size approx 2.8-3.4 MB. Thanks Fellows!

you should contact Kuka about changing memory size reserved for vxWorx
I wnader if u guys solved this issue , have same robot and wanted to find solution, sometimes kuka shows files more then 5mb sometimes no, and even if max line is 30000 doesnot metter software will work fine
There is no solution. The robot has limitations about the occupied amount of bytes in memory. You have to live with it.
Everything is already said, but not from everyone.
Also there is no chance to increase virtual system memory right? putting more memory can fix this problem?
Read and understand all of the above posts, everything is said.
No. Putting in more memory only increases available memory on Windows and not on VxWorks side of the controller. VxWorks memory is limited due the maximal value allowed by the VxWorks operating system.

the max line you are talking about is actually the max line you can see in the bof editior (why would you want to see them-you can simply use a standard editor to view)?
first
only use *.src and no *.dat file to store or your points (extra memory)!
second
If you have only points with constant orientation define the first point with x,y,z,a,b,c and for all the other points only use x,y,z (this saves al lot of space)
third
check this forum because earlier I already gave some advice.
Add on:
vxworks memory is actually protected memory and can not by accessed by windows!
