I hope I don't find another broken one or even break one when I take it apart. The problem here was I can't easily get to the left side bracket to see if it was cracked. I tried to get my camera in there to take a picture but even that was tough. So I won't know until I take it apart. And if its broke, I'll be waiting another week for a replacement. There are numerous posts about these breaking on various forums so I know this isn't a rare issue. And many people reported getting full sets of brackets.
I do appreciate the follow-up support for the Davinci warranty. They have replaced everything I showed as failed so far including my extruder which I posted about prior. From now on though, I suggest you make sure you spell out everything that is wrong before making a request for replacement. I know I will.
XYZprinting, if you are listening, thanks for the replacement but in the future at least send a pair or a full set of four.
