Well this week I found 2 videos to help prevent this. Even though my other cutting plates don't look this bad they still warp. I keep at least 3 sets of plates - one for the cutting surface of my dies, one set for the top of the sandwich that does not touch the cutting edge and one set just for embossing folders. I also have 2 cracked plates. They cracked after 8 years of use and I now keep them handy to use with the precision plate, because I hated mine warping.
So I found a video that Sizzix made on how to use the plates so they don't warp.
Even though I turn mine a lot I seem to always cut in the same place since a lot of mine you really can't place different places because of their size.
Now here is one with just the Precision Base Plate.
I hope this helps you I am going to try this to see if it helps.
