Been thinking about your hoop problem. Is there a chance the dealer gave you the wrong one? In a new owner's class recently, a student could not attach her embroidery unit and it turns out that 3 weeks previously she had been given one for a different machine. No wonder she couldn't make it work!!!
Most hoops have a screw that you can loosen and tighten - have you done that?
As its now shops open time in the Uk and am I correct its a new machine contact the dealer and ask for help. Brother hoops are easy to fit, I have worked with over 10 different Brother machines and the hoops all go on smoothly
Yes I think it's a problem with that particular hoop as the other one goes on fine each time.
Two hours later and I still can't get it on, but still the other hoop goes on fine. I think it's time to go back to the shop and complain!!!
I sure would, definitely has to be something wrong with that particular hoop if the other one goes on so easy .... off ya go to the fix-it-shop !!!
