Download Bernina Simulator 790 or 880

Posted by Alfonsina Uriburu on

You don’t need a Bernina 790 or 880 to use the Stitch Designer on your 740/770/570/590 or other 9mm Bernina sewing machine with a USB port. Just download the 790 or 880 simulator and modify or create new stitches directly on your PC! And you can even use your mouse instead of the stylus to draw your stitches!

Copy the stitches from your simulator’s “virtual” USB drive to your physical USB drive and transfer them to your sewing machine.

You can also do this in reverse and modify existing stitches on your machine (like a 570/590): save the stitch on your machine to your USB key in the favorites heart folder, then copy the stitch file over to the simulator’s virtual USB drive. Modify the stitch in the simulator and copy it back to your sewing machine!


  1. Download the Bernina simulator from the Bernina website
  2. Launch the simulator and create a new stitch, click the green “Save” checkmark:

    Design Your Stitch

    Design Your Stitch
  3. Go to the Heart “favorites” and save the stitch to USB :


    Save Your Stitch to virtual USB
    Save Your Stitch to virtual USB
  4. Open the virtual USB drive by clicking the USB stick icon in the simulator.
  5. It will default to the virtual USB Embroidery directory (EBY_PC_CARD), so move up a level and go into the virtual USB sewing directory (SEW_PC_CARD) :


    Choose SEW_PC_CARD directory and copy your stitch file
    Choose SEW_PC_CARD directory and copy your stitch file
  6. Copy your new stitch file to your real USB drive and copy it over to your sewing machine!

Now you`re ready to custom stitches for Bernina users to share – if you create some nice ones, share in the comments below!

Tips for stitching decorative stitches

Embroidery success starts with needle and thread.

Select a needle explicitly designed for machine embroidery changing often.

Choose a good quality machine embroidery thread explicitly designed to withstand the heat and friction associated with high speeds of embroidery.

Next, select an embroidery bobbin thread, typically lighter in weight than machine embroidery thread, to aid in pulling the top thread to the backside.

Maintenance for the best results

Clean and oil the machine every 3 to 4 hours of stitching time.

The high speed of embroidery creates more lint and fuzz than encountered during regular sewing.

Tension Troubleshooting

Bernina simulator

The rule is to see on the wrong side of the fabric 1/3 bobbin thread and 2/3 of top thread

Higher upper thread tension = the upper thread is tightened, which pulls the lower thread up to the topside of fabric.

Lower upper thread tension = the top thread is loosened, which allows you to pull the backside thread of the fabric.
