Color Change Mechanism | Redline Embroidery Machines 

Thanks for your videos. I bought a similar machine (QHM) and there's still some set up that wasn't perfect. I'll use this information to center my needle.

really nice close up view

For a 12 needle machine, do you have to set it at needle 8 too?

When i take the mechanism i have an obstruction . I cant move the sewing head side to side. What could cause this?
