Prime Blob Getting Squished

[dcschooley 9]

When my S5 finishes doing a prime blob, the bed starts to rise before the print head gets out of the way. The prime blob gets squished against the bottom of the print head and dragged to some random, undesirable place. I'm using a prime blob because I'm also using a powder-coated PEI plate, and single layer skirts are a pain.

 

It started doing this recently, but I don't remember when. My S5 is running firmware version 6.2.

 

Someone else had this same problem with UM3 several years ago.
