for the past few days, when im embroidering, im having a problem. the first color stitches, and all is fine, then i load the second color, and it stitches is slightly out of position with the first color, causing them to overlap or have gaps. it doesnt do it every time, but its driving me nuts and costing me in materials. any suggestions would be great. for reference, i have been using this machine to embroider daily for 2 years (this is my second machine in that time, as the first one got damaged in a house fire) and in that time i have embroidered literally hundreds upon hundreds of items (kind of a small business for me), so i know its not my digitization software. any help would be much appreciated
