What happens to your XXX file
Every needle point lands in the same place in the PEC file as in the XXX file, and Hoopbench reads the new file back to prove it before you save it. The details below are what actually changes between these two formats.
| Stitch positions | Identical, to 0.1 mm |
|---|---|
| Colour stops | Same number, same order |
| Thread colours | Matched to the Brother chart |
| Size and density | Unchanged |
Thread colours
XXX stores real colours, and PEC needs a thread from a fixed chart. Each colour moves to the nearest in the Brother chart, so close shades can land on the same or a slightly different thread.
Long moves
PEC can move 204.7 mm in one record and XXX only 12.3 mm, so everything fits. Chains of jumps from the XXX file stay as jumps.
Trims
PEC marks moves with a trim flag, so each trimmed move carries across. Brother machines cut on these moves, depending on the machine's own settings.
Before you stitch
- Open the .xxx file above and watch it sew, so you know the file is sound and in the order you expect.
- Choose your hoop under Hoop fit. The check uses the design's real size, not the file's header.
- Download the .pec file, and stitch a test piece on matching fabric and stabiliser.
Converting doesn't resize a design or change its density. If a design needs to be much bigger or smaller, use digitising software, as stretching stitches without recalculating them can leave gaps or heavy spots.
About XXX
XXX is the Singer format. It has a 256 byte header, then stitch records, then a table of real colours after the end marker.
Thread names and catalogue numbers. Only the colour value is stored.
About PEC
PEC is the machine section of a PES file on its own. It holds stitches, a list of slots in the 64 colour Brother chart, and small black and white thumbnails for the machine screen.
The PEC file is for tools that use the Brother machine data on its own. Tools that ask for PEC by name. Otherwise choose PES.
Most people want PES rather than PEC, unless a specific tool asks for PEC.
