Problems with Viking Rose
 

Larry, I've taken your advice, learned the Husqvarna Designer 1 machine & done everything possible to fix it that was in the service manual & online. Sensor still does not recognize hoop size. I've successfully adjusted & calibrated every step, except one - I can't get belt in embroidery arm to return to calibrated position - it always returns to various positions, leaving it off mark, so sensor senses hoop as being wrong. How do I adjust the belt calibration accuracy? Could it be needing a software update?
