1 - Are you getting thread breaks on all needles or is it isolated to a particular needle?
- If you are getting thread breaks equally on multiple needles the problem could be from:
- poor hooping or incorrect stabilizer
- the bobbin is in correct - make sure that when it is in the machine it unwinds counter clockwise
- the presser foot could be too high
- a poorly digitized design
- a burr on the needle plate
- an incorrect setting in AMAYA OS - make sure you are stitching on auto instead of standard.
- least likely... your hook timing could be off.
- If just certain needles are giving you problems start by:
- checking the thread path and make sure the thread isn't getting stuck under the cone or wrapped around the thread tube
- using good thread (I like Iris polyester thread from EnMart)
- make sure the thread is coming off the cone smoothly
- the machine is threaded properly
- the needle is installed properly with the thread guide to the front.
- If everything looks okay with each of these things then try putting in a new needle... sometimes that does the trick.
