Herb, I haven't had a great deal of experience with the "thread feed fine tuning" feature under the settings tab. Although I think it's great to have it there in case we need it, I feel it's one of those bells or whistles that are not practical for our needs. My thoughts on this is that a MT of 3 or 4 or whatever whole number you choose, usually does the trick simply because the bobbin is capable of "taking up the slack" (figure of speech) in this area. The bobbin should be allowed to slip through the bobbin case so that the bobbin will dispense as needed after the thread feed system has delivered all it's going to deliver. Meaning that if the thread feed system was set too low, and there wasn't enough thread for that stitch, then the bobbin will have a greater length. If the MT is set too high, chances are that you won't see any bobbin because it wasn't necessary as the excess thread wrapped around to the back side of the garment where the bobbin usually is. If the thread feed is even higher than that, the exceptional amount of excess thread has no where to go so it sits up on top and bottom of the garment creating "Looping". Now there are a couple of things that can change what we think is controlled by the Material Thickness. Not only do you have the setting in software (3,4,...) but if the bobbin tension is incorrect or simply dirty, or the thread feed roller is dirty or has grooves, or if the thread path is obstructed, or if the fabric is moving due to stretching or flagging, etc... But I know you know all about these issues already. My question for you is that you say if you step up to a number 4 in MT, then the sewing looks like crap. How would you describe the crap in question? (If you know what I mean.) I would think that using that "fine tuning" feature would be used for something you were going to run a lot of, and had all new and clean parts (specifically thread feed rollers). Features like this and the "settings by color" option are not practical if you are only running, as we call them, "onesies". If I were going to run three of the same thing or more, I might think about how to optimize my time by utilizing these features. If you wind up playing with the fine tuning thread feed feature, my only recommendation to you is to practice to get an idea of what a change in number will result on the garment and be sure to use new thread feed rollers and have a clean bobbin case with correct bobbin tension. I say this because you don't want to have variations caused by other areas when you are focusing on only one. Best of luck to you. Ed Ed & Maralien Orantes E.M.

Is there any way to determine what % of change you have just created. I have a situation where a 4 breaks thread, little to no bobbin showing so I drop to a 3 but the finished product looks like crap. Go to settings and add thread feed but I don't have enough experience with this to find the "sweet spot". Maybe I am being too conservative in the amount of change. Is a MT of 3 and thread feed of 40 actually a 4????? ANYONE??? (Need more Experience) Herb Royal Embroidery
