Does your machine stitch other designs OK?
What stabilizer are you using and how are you hooping the project?
Sticky back stabilizers can gum up the needle and cause issues.
Check the bobbin area and make sure it is clean. Are you using a pre-wound bobbin or one wound on the machine?
Change the needle. This is always my go-to when having issues.
Make sure the needle and the embroidery foot are seated into the correct position and the holding screws are tight.
Did you edit, change size, or position of the design? Delete this current design from the machine for stitching and then start over selecting the design.
