First a Disclaimer: If you damage your sewing machine by using these discs, I won't take any responsibility. Make sure you test the disc by turning the handwheel till whole disc make one revolution before using with the motor, check if the needle is not hitting the presser foot or anything else. These discs are created with OpenSCAD file made by wileur, which can be found here: https://www.thingiverse.com/thing:3268941 Discs are uploaded on request from Singer 431G group. The heart shape disc needs really short stitch length, like satin stitch, just play around with the stitch length till you get best result. There are 2 ECG heartbeat discs, one with the peak on the left side and one with the peak on the right side.again play around with the stitch length to get best outcome.
