First off, I don't know anything about the Singer 6268. However, I
do have two Singer XL6000 embroidery machines, so perhaps some of my
experience will translate to your situation.
On my Singers, the embroidery unit must be slid all the way into
position and a lever moved to the right to engage it. Be sure yours
unit is fully in position and any locking-switch is engaged.
Each time I turn my machines on (in embroidery mode), there is a
"welcome" screen, followed by an "initialization" screen, which
requires that I touch "OK" and the embroidery unit moves (presumably
to make sure nothing is blocking the area). Does your machine have
this requirement, and if so, does the unit move?
