Iris,
True, your bobbin column, however thick or thin should be centered down
the column on the backside of the fabric. If the bobbin column is shifted
to one side of the column, something may not be right. Without getting into
something complicated like machine timing, let consider something simple
like your bobbin case. I have seen bobbin cases that were bent and causing
the bobbin spool to rub as it rotated inside of the bobbin case. I've also
seen where one specific bobbin spool was not shaped correctly and had a
"high spot" which would rub on the inside of the bobbin case inconsistently.
I have met a good number of folks that did not truly understand the benefits
of "Consistent Bobbin Tension" and the causes of inconsistent tension to
look for.
When sewing smaller column widths, as opposed to larger widths, your
tolerances are much tighter giving a greater opportunity for bobbin to show
on the surface. One quick way to check if this is the problem is to change
to a new bobbin case with a new bobbin installed set with the proper
tension. If a new bobbin case solves your problem we could then go into
trouble shooting your original case to see what needs correcting.
As for the 30,30,30 concept,... that is preferred or "balanced" as some
say. Realistically, you could have a wide bobbin or a narrow bobbin as long
as the front side of the embroidery looks good, is not too tight and not too
loose. I use the analogy of driving a car down the highway. You are
supposed to drive down the center of the lane. However you could drive to
the left side of the lane or the right side of the lane and even all over
the lane. Just as long as you don't go off the lane, you can still make it
to the grocery store as intended. Quite possibly a little sick from the
swerving and with a bunch of reckless driving tickets. My point is that you
can try to get your bobbin perfectly centered every time but it's okay if
your bobbin width varies a little. Of course if your bobbin width is too
wide, then you will see bobbin showing itself on the front side of the
garment and that is unacceptable.
Try a new/clean bobbin case and let us know how it goes.

Yeah!. My mistake with the nos. It is 30,30,30. But the columns that I
am sewing are 7pt, 9 pt , 18 pt being the highest in this one. It
consistently seems to slide to one side, causing bobbin thread to show up on
the front. I am ok with tightening the bobbin thread a little, but
tightening it so tight that it does not drop is completely against what I
have learnt and applied so far. MT being 7 for a easy care shirt, it
frightens me since I worry it will cause holes or so in the garment.

For as long as I have been doing embroidery it has been 1/3,
1/3, 1/3. For narrow satin stitches (columns of 3mm or less) you may want to
run a little tighter bobbin tension, showing less than 1/3 on the back.

Hello All,
I wanted to check with you to see if anyone has the same problem as
me.
When I do small lettering, my bobbin thread seems to slide off to the
left. (In class we learnt, it should be 30,60,30 with the bobbin thread in
the middle.) This some times causes the bobbin thread to show up on the
front of the design causing dandruff. The tech checked it and said
everything looks fine with regards to the bobbin positioning and so on.
But every time I do small lettering, I see the dandruff. I was sewing out
the easy care shirt maroon color and the white thread showed up so clearly.
The tech suggested that I tighten the bobbin completely and increase the
material thickness to counter that and it would solve the problem. (For a
easy care shirt, the MT was 7). To me, this was not a solution, but a work
around.
Do any of you have this problem? How did you solve it or do you just
live with it.
I would be interested to hear what you all have to say.
