Im trying to do this cube 8x8x8 wirh
1 uln2803
875hc595
I have 3 time doing this and none work
Something is wrong or is imposible to make it work with this pcb ??

You need to read up on how to post your code and include images. People are less inclined to download attachments (malware, etc.) and you therefore limit those who might otherwise offer assistance. I downloaded your other file, but time to do things different. If we do download, we look at it, comment and then generally move it to the trash bin, otherwise the file of downloaded snippets grows and grows. Also, referring back to the original post, there's no reference unless one is prepared to download again and again, or hold on to the initial download. Good luck.

Ok bro i will do that. Thanks for answer. It..

Please explain exactly what you mean by "none work".
Please always do a Tools > Auto Format on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. If you're using the Arduino Web Editor you will not have access to this useful tool but it's still unacceptable to post poorly formatted code. I recommend you to use the standard IDE instead.
None ledd turn on..
Start with a simplified sketch that only blinks one LED.

I see the problem! The 595 shift register on the right is cut in half.
I can't see your code though. Is there something in it that prevents your circuit from working? Check out this thread, for some hints on how to supply enough information to get effective help.
