3/14, 04.11.2009

2 SEWING UPDATES
2.1 Thread tension for the underlay segments (buttonholes)
To eliminate possible thread loops, the thread tension for segments with short step stitches is inc-
reased from 2.0 to 3.0.
2.2 Manual threading
In some cases during manual threading, the thread swing support mechanism can be blocked.
This update avoids this issue without performing any mechanical readjustments.
4/14, 04.11.2009

2.3 The use of straight stitch feet with thread cutting
The opening of the straight stitch foot is 0.4mm on both sides. The “tie on” stitch after cutting is
0.4mm to the left side. After thread cutting, the first stitch failed resulting in the animation “need-
le will penetrate presser foot” due to the narrow tolerance in the foot opening. This has been
resolved.
2.4 Disable automatic thread cutting when opening the bobbin door
Previously the thread was cut automatically before the hook turned to the front.
To accommodate the need to change the bobbin without cutting the upper thread, the cutter is
disabled and the “lower thread empty” message appears.
2.5 Thread cutting without fabric movement
Thread cutting with the needle stop down, will NOT result in fabric movement.
2.6 “Manual” winding of the lower bobbin thread
The filling process stops at a detection of 100% fill level. As a result of mechanical tolerances, it
is possible that the bobbin does not fill to the maximum capacity.
5/14, 04.11.2009

In addition to the “automatic” mode, an extended manual mode is implemented.
This mode gives the user the opportunity to start and stop the winding process by
holding and releasing the winding button.
2.7 Winding indicator during sewing/embroidery
When closing the winder menu during winding, the clock symbol changes to the
winding symbol and allows switching back to the winding menu.
2.8 Reset of back stepping history
Lifting the presser foot when the needle is up automatically deletes the back stepping history in
memory.
6/14, 04.11.2009

2.9 Thread breakage hint
If the thread breaks, press the threading button to open the thread tension and remove the th-
read. Rethread the normal way.
2.10 Problem with Foot #57D and straight stitch compatibility
Select stitch #1, attach and select the foot #57D (Patchworkfoot with guide).
Open the securing function and select the straight stitch plate.
Now, it is possible to start the sewing process, without the warning message appearing:
7/14, 04.11.2009

2.11 Presser Foot #0 can be used for automatic threading. With the “Walking foot”
automatic threading is not possible
The original help text mentioned that the machine cannot be threaded automatically with foot
attached. New help text implemented:
2.12 Information Foot #2a corrected
Data correction of the dimensions of the presser foot sole.
8/14, 04.11.2009

2.13 Pattern #169 improved
Elongation limited to a maximum value of two for optimal results.
2.14 Tension changed for the “tie on” stitches
To improve the “tie on” quality with stretchy threads, such as polyester, monofilament etc. the
tension setting for the first four stitches is reduced.
2.15 Upper thread detection changed
To prevent an inaccurate warning messages from the upper thread detection, if the thread tensi-
on is detected not to be correct the machine now stops after eight stitches.
New: Before:
Max. Warning Stitches = 8 Max. Warning Stitches = 6

3 EMBROIDERY UPDATES (BERNINA 830 ONLY)
3.1 Start of embroidery
If the Start button was pressed while the bobbin door was open, either the embroidery start was
not possible or the start position was incorrect. This has been resolved.
3.2 Using zoom option with panning
When using the zoom option, only the view of the design will be moved. The hoop position rela-
tive to the design will not be changed.
3.3 Using Foot #44C (The new CutWork & Echo quilting foot)
Developed for the CutWork tool, this foot can also be used for quilting.
For designs with “cut” and “normal” embroidery layers, the foot #44C can be selected in the
stitch out mode. The outlines for the selected foot will be immediately set. The position of the
design will not change.
10/14, 04.11.2009

3.4 Thread tension can be changed to a minimum of 0.5
A new parameter controls the minimum thread tension range (between 0.0 - 1.0)
In the embroidery mode, the thread tension can be lowered to a minimum level of 0.5, instead of 1.0.
When decreasing the tension values to less than 1 a warning message appears.
After confirmation, the minimum tension of 0.5 can be set.
11/14, 04.11.2009

3.5 Stop for manual cutting can be switched off
Deselecting of the scissor symbol, will disengage the stop sequence for manual
cutting at the beginning of a design or color.
3.6 Manual “tie on” for embroidery
Disabling of the “tie on” button will disengage the automatic tie on.
User brings up the lower thread manually and during the first stitches the thread
must be held.
Attention: If “tie on” is deactivated, the setting for jump stitches will be ignored and the cutting
of jump stitches is NOT possible.
When the machine is turned off it returns to “activated”.
12/14, 04.11.2009

3.7 Delay of Start/Stop button has been reduced for embroidery
Delay time reduced from 800ms to 200ms
3.8 Thread breakage during jump stitches
The tension was closed during the module movement when the function “cutting of jump stit-
ches” was disabled. This potentially caused thread breakage. This has been resolved.
3.9 Stitching “without thread”, is displayed in embroidery mode
As is in sewing mode (in setup), the selected “no thread” mode will be displayed.
4 IMPORTANT POINTS
4.1 Hoop calibration
Calibration of hoops has to be done after updating the BERNINA 830.
4.2 Feedback issues
Please inform BERNINA (standard information way) about any unusual crashes, error messages
and malfunction in form of a log file. Please document every step of the application and manipu-
lation that led to the malfunction so that the process can be reproduced.
4.3 Free memory
If there is nothing stored on the sewing machine memory and the free memory counter does not
show 100%, the software version has to be updated again (this will free all allocated memory
not used).
