Found the reason…
Whole thing moved on me. Totally mg fault. Idk why I didn’t put any screws on the side.
Here’s the fix…hopefully
Now while the glue dries I’m going to attempt to go back though the code and find just the end section for each layer and made a new file with just those and then pick up where it left off at the end of the 20mm layer. Wish me luck lol
