Just wanted to throw this out there for those who get this in the mail. It was probably more obvious to others but I missed it for a while. This is my first 3d printer.
The only foam visible right off is the larger foam rectangle in the photo, which I removed like the instructions say. Later, after having issues, I found the two small foam blocks wedged tightly between the bed and rail/belt on the Y axis. To some it might not be so obvious.
