Eagle manual route bottom layer crash

[jantje1994]

Dear,

I was working on a 2 layer PCB. I routed some traces on the top layer without any problem. However when I tried to do the same with the bottom layer Eagle suddenly quits/crashes. I tried using other names because this was mentioned in other posts with similar issues but this did not help. Names do include a _ but this is not a problem for the top layer.

Is there anyway to solve this issue? I would like to finish my PCB soon.

I have included a screen recording of the crash. I also have a .dmp file but I could not upload it to the forum. 

I'm using eagle 9.6.2 on OS X

kind regards,
Jan de Jong

Update. I also tried doing the same on windows on the same project using v 9.6.2 with the same result.

Hi @jantje1994 ,

I hope you're doing well. This is really odd, would you be willing to share the files for review. I can't think of any reason why it would crash when you switch layers.

Let me know if there's anything else I can do for you.

Thanks for the reply @jorge_garcia I've attached the brd and sch file for evaluation. I do not know a way to send you the crash dump file, at least not on this forum. In any case, thanks in advance!

Hi @jantje1994 ,

I hope you're doing well. I tried playing with the file a little and I'm not able to get it to crash. Could you give me an example of a trace that causes EAGLE to crash? Let me know if there's anything else I can do for you.

Best Regards,

Hi @jantje1994 ,

I hope you're doing well. After speaking to the developers, they let me know that it's a known issue caused by the persistent groups that you have created on the board. If you remove those the crash should go away. That would be a possible temporary workaround.

Let me know if there's anything else I can do for you.

Hi @jorge_garcia 

I think this solved the problem! Thank you so much! It was a bit frustrating not to know what was causing all this. Thanks for the quick replies.

Kind regards,

how do you remove "persistent groups"? so that I can route on the bottom layer.

Hi @EthanTristanLeeDude ,

I hope you're doing well. In the Design Manager Browse Tab, set view to Groups. That will show you the persistent groups in your design, you can then right click the groups and select ungroup.

Let me know if there's anything else I can do for you.

Jorge,

For one, removing unwanted groups didn't fix the problem.

For two, my colleague routes on the bottom layer on his computer, the program doesn't crash.

So what ever the issue is, it is related to the computer, not the group settings. 

I read on a different forum that It could be releated to the graphics card, and that starting the program using the eagle_SW_OpenGL.bat could force the computer to software rendering, and fix the issue. I tried that as well, but it didn't work either.

I'd like to get someone on the phone or screen share to expedite the resolution of this issue. is that possible. other wise, is there something else I could try?
