Hello & Welcome!
Have you stitched this design before? Issues?
What needle type and size are you using?
What type of bobbin, stabilizer, and fabric are you working with for the project?
What kind of thread? On a stand or on the spool spindle on the machine?
I don't think it is the machine. Most likely it's a combination of techniques or products that are causing the issues. Most common are needle issues. I like a Micro-Tex 80/12.
How often are the needles changed? LQS recommends every 8 hours of sewing/embroidery to change them.
