StitchPilot.aiMachine guide · EXP format
Bernina embroidery machines use EXP as their primary machine-ready format. This guide covers EXP format basics, hoop size planning, USB transfer tips, color sequence management, and workflow advice for getting the best results from Bernina artista, aurora, and Q-Series machines.
Working with Bernina machines
Bernina machines vary significantly by series. artista and aurora models have different maximum embroidery areas and hoop sets. Confirm the largest available hoop for your machine and plan your design size accordingly before digitizing.
Use StitchPilot.ai to convert PNG, JPG, SVG, or WebP artwork into EXP format with AI-assisted digitizing. Review the stitch preview for fill coverage, color stop sequence, and edge quality before downloading your file.
Copy the EXP file to a FAT32-formatted USB drive and insert it into the USB port on your Bernina machine. Navigate to the embroidery selection menu, load the design, and set the color sequence manually using your color stop list.
Use your machine's preview function to check scale and placement, then run a test stitch on scrap fabric with the same stabilizer as your production material. Adjust thread tension and stabilizer weight as needed before the final run.
Bernina machine series
Bernina's embroidery lineup spans from entry-level models to the premium Q-Series multi-needle machines. EXP is the common denominator across most Bernina models, while ART files are used within the Bernina software for design editing and color management.
EXP format and color management
Because EXP does not embed color data, you will need a color sequence reference when stitching out a multi-color design. Create a color stop list alongside your EXP file — noting thread brand, color number, and stitch order — so the machine operator can set colors accurately.
Bernina machines — common questions
Bernina machines primarily use the EXP format (Melco Expanded format), which stores stitch data without color metadata. Bernina software also works with ART files for editing, but EXP is the machine-ready output format.
Transfer EXP files to a Bernina machine via USB stick. Format the USB drive as FAT32, place the embroidery files in the root directory or a simple folder, and insert into the machine USB port. Navigate to the embroidery menu to select the file.
No. EXP is a stitch-only format with no embedded color data. Color changes are indicated by color stops in the stitch sequence. You will need to assign thread colors manually on the machine or refer to a color sequence sheet.
Some Bernina models support DST files, but EXP is the native Bernina/Melco format. Using EXP ensures the best compatibility with Bernina embroidery software and machines.
Before production, check that the design dimensions fit within your hoop, review the stitch preview for coverage and edge quality, confirm the color stop sequence, and run a test stitch on scrap fabric with the same stabilizer as your final project.
