I use Windows 10, e4 decorating, on a Happy 1501. My dilemma is there hasn't been a circle design that has stayed a circle. All my attempts on caps, patches, anything circle related is distorted. All my circle designs have been 2" or larger. Any help is greatly appreciated.
Lookup John Deer's Embroidery Legacy on Youtube. He has a lot of videos you can learn from him how to digitize circles. He has a few videos about push and pull compensation.
