Not much to add other than echoing using the correct type and size of new needles and using good quality branded thread such as Gütermann. Don’t waste your money on cheap threads from Aldi or Lidl.
Schmetz also have an App you can download to your phone with needle info on. Can be handy when you’re out shopping and buying fabric to also buy the matching thread and correct needle at the same time.
My Juki hated Moon thread and anything vaguely fluffy but the Brother machines seem far less fussy.
Also, I bought some pretty metallic embroidery threads that I use when jazzing something up. You definitely need to use the correct needle though as too small an eye will shred the thread.
