Prints are Jumping to Layer 426 after printing Layer 1

Not sure what is going on lately. I start a print and the first layer prints then the vat does it’s tilt then the build plate rises and wants to start printing on layer 426 or 124 or what ever it wants to print next. This has happened on new prints and old ones that used to print fine. I’ve tried re slicing them and nothing seems to be working for me now. Any idea what this could be? I am using the new leveling plate and new vat, all was working just fine till about 2 days ago. Ran a pillar test and all was fine with that … heights were almost perfect. Any help would be appreciated.

This sounds like a SD card issue, re-format the SD card and you should be good to go, remember to put your files in a folder in order for the reader to read it correctly
