What happens to your PCS file
Every needle point lands in the same place in the XXX file as in the PCS 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 | Carried exactly |
| Size and density | Unchanged |
Thread colours
PCS and XXX both store real colour values, so colours carry across exactly. XXX cannot hold thread names, so those stay behind.
Long moves
PCS stores absolute positions, while XXX moves up to 12.3 mm per record. Longer moves are split into a chain of jumps.
Trims
XXX has a real trim command, so cuts carry across as cuts.
Before you stitch
- Open the .pcs 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 .xxx 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 PCS
PCS is an older Pfaff format. Unlike most formats, it stores the absolute position of each stitch, in units of 0.06 mm rather than the usual 0.1 mm.
Trims. Rounding to 0.1 mm can also move a stitch by a tiny fraction of a millimetre when you convert away from it.
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.
The XXX file is for Singer machines and the software that shipped with them. Singer machines that read XXX.
Singer home machines have long, narrow hoops on several models, so check both the width and height.
