Taz 6 - Bottom Half Print Deformation

I’ve been using this Taz 6 for several years without issue, until recently. I blew a fuse on the Rambo board, and have replaced it, but ever since then, the bottom half of everything I print is now distorted (like it has shrunk), then it corrects itself and the top half prints fine. I thought it was my model, so flipped it 180° with the same result. I tried a different model and got the same thing. I’m at my wits end here with a back log of prototype prints required here at work. I’ve attached a link to an image showing my issue. https://www.dropbox.com/home?preview=20190530+-+3D+Print+Issue+marked+up.jpg

Any help is appreciated.
