Ok....I stand completely humbled...I read the manual ...what a concept....anyway, after buttonhole instructions there was button instructions and yes attachment M is what I use, so I have regained my confidence in this machine.
When I do buttons by machine, I always hand turn the wheel for both holes before I step on the gas..and needle usually set at 3... Zig-zag whatever makes the swing....here's a bit of info I learned along the way....somewhere...all.buttonholes are the same distance between holes......I guess an industry standard.......
Anyway, thanks for reading my answer do my own question
