Should I update GC to the latest version?

My Maslow has been idle for about 9 months and I am getting ready to start a new project. I am currently running GC 1.15 and have had good luck with that version. My question is, if I update to the latest version of GC will I need to re-calibrate the system and will I see much improvement in the accuracy?

We have at least one that is sticking with older version of FW/GC.
Generally it’s advised to update to the latest, however, you could check the ‘release’ page on git-hub and look at the changes if there is something significant enough to update.
If your tolerances are ok, you should not need to do a new calibration.
