What’s New & Technical
If you move a module from one machine to
another (200, 730, 430, 435, 440, 630, 640)
you must recalibrate the large hoop with the
appropriate grid (purple for 200/730 and orange
for 430-640).
The module calibration is slightly different on
some of these machines and if they are not
recalibrated when swapped or if the wrong
grid is used the module will not perform correctly
and you may also get error messages.
Some issues that may come up are the machine
stitching in place when in embroidery,
mega hoop designs do not go to the correct
section or embroidery sews in place, the embroidery
foot bumps the edge of the hoop, etc.
Once the machine and module have been
recalibrated the embroidery should function
normally

When removing the thread from an 830 be
sure to cut it at the spool and pull it from
the needle through the machine’s tension
unit. If you pull the thread from the spool
end it goes backward through the tension
unit and could possibly damage components
within the tension unit and threading
mechanism. We have replaced check
springs, complete tension units and the first
thread guide on machines that have had
thread pulled through them incorrectly.

This really should be done on all bernina machines the way they are designed at the take-up lever.
