Steps

Export one DXF per sheet from Zorocut (profile R2000, or R12 for older software)
Import it in CypCut and map the ZC_ layers in the Layer mapping dialog
Add lead-ins, kerf compensation and micro-joints in CypCut, check the path, then cut

Which controllers this covers

FSCUT2000C and FSCUT4000 controllers ship CypCut as their control software; the EtherCAT models FSCUT2000E and FSCUT4000E run CypCutE. All of them read DXF and clean it on import: they remove tiny shapes and duplicate lines, join unclosed shapes, smooth, and detect inner and outer contours. An open contour is not a contour to CypCut — it is drawn in red and not cut as a part.

What Zorocut writes

Item	Value	Why
Format	ASCII DXF R2000 (AC1015); R12 as an option	Lines, arcs and circles are valid in both, so R12 costs nothing
Units	mm ($INSUNITS = 4)	One unit, stated in the header
Entities	LINE, ARC, CIRCLE only	No splines, ellipses, polylines or blocks for an importer to smooth or misread
Arcs	The original arcs, moved and turned — never re-approximated	Holes stay round; nothing for import smoothing to change
Joints	Consecutive segments share identical end points	Contours close at any import tolerance
Origin	The sheet's lower-left corner at 0,0; one sheet per file	Predictable placement on the table
Not written	Lead-ins, kerf compensation, micro-joints, G-code	The controller adds them; Zorocut never drives the machine

The layers

DXF layer	Contents	Map it in CypCut to
ZC_CUT	Cut contours: outlines and holes	A cut layer, e.g. layer 1 (or this material's process layer)
ZC_MARK	Marking	Layer 15 — CypCut runs it first
ZC_ENGRAVE	Engraving, open paths allowed	A marking layer
ZC_LABEL	Part names as text (option)	Layer 0 — not processed
ZC_SHEET	The sheet outline (option, on a layer that is switched off)	Layer 0 — not processed

Nothing is written on DXF layer 0. CypCut's own layer 0 is its background layer, which is never cut, and AutoCAD's default layer is also called 0: keeping it empty means the two are never confused.

Map the layers once

Import the DXF in CypCut. When the file has more than one layer, the Layer mapping dialog opens.
Assign ZC_CUT to your cut layer, ZC_MARK to layer 15, and ZC_LABEL and ZC_SHEET to layer 0.
Leave the import optimisation (File → User parameters) as it is: on a clean file it finds no duplicates or gaps to fix.
Add lead-ins, kerf compensation and micro-joints with CypCut's own tools, check the cut order — CypCut can sort it again — and simulate before cutting.

Because Zorocut always writes the same five layer names, the mapping is the same on every job. Whether CypCut remembers it between imports depends on your version — the manuals we read do not say.

Common problems

Two parts sharing a line: CypCut removes duplicate lines on import, so a shared edge could leave a contour open. Zorocut never writes two parts on one line — the part spacing is always above zero — and leaves common lines to CypCut's co-edge tool (common-line cutting).
Wrong scale: the DXF is in mm. If CypCut shows the parts 25.4× too big, it is reading inches — see DXF units.
Labels being cut: map ZC_LABEL to layer 0, or switch Part labels off in the machine's export profile.
Older software that cannot open the file: switch the machine's export profile to R12. The entities are the same; only the header is older.
