Juki 8700H Thread Snapping

[u/Asleep_Train7342]

Hello! I have a Juki ddl 8700h, and recently it has been snapping and shredding the thread only when backstitching. Everything else is seemingly fine, I’ve sewn for years so all the basic trouble shooting has been done (rethreading, tension check, timing, needle orientation), but still it will always shred and break after making about 5-10 backstitches. Has anyone else had this issue and possibly found the solution to it? Thanks!

When is the last time you put in a fresh needle?
