URS Polyscope File

I noticed that the recent Polyscope updates for the UR3 show -build in the file name starting @ 3.15.4. Is this a different file? I need to replace a joint and want to make sure this is the correct file.

As long as you are downloading your software from our support site, the file is correct. Read the instructions on the download page carefully. CB series robots must be updated incrementally, and downgrading software is not supported.
