Class MachineCoordSelectSyntax

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

Handles G53 (machine coordinate selection) — non-modal, one-shot. The axis values (X/Y/Z) in the block are interpreted as machine coordinates, bypassing all work offsets, local coordinates, tool height compensation, and coordinate rotations. If G91 (incremental) is active, G53 is ignored per ISO standard.

Must be placed before ProgramXyzSyntax in the syntax chain. When G53 is active, this syntax consumes X/Y/Z from Parsing and writes MachineCoordinateState directly, preventing ProgramXyzSyntax from processing them as program coordinates.

Examples

G53 with full XYZ on a first block (no #Previous:) — FindPreviousMc falls back to Vec3d.Zero, transform defaults to identity, so ProgramXyz equals MachineCoordinateState: #BeforeBuild:

{ "Parsing": { "Flags": ["G53"], "X": 10, "Y": 20, "Z": 30 } }

#AfterBuild:

{
  "MachineCoordinateState": { "X": 10, "Y": 20, "Z": 30 },
  "ProgramXyz": { "X": 10, "Y": 20, "Z": 30 }
}

G53 with only Z specified — FindPreviousMc picks up X/Y from the previous block's MachineCoordinateState; Z is overwritten: #Previous:

{ "MachineCoordinateState": { "X": 100, "Y": 50, "Z": -200 } }

#BeforeBuild:

{ "Parsing": { "Flags": ["G53"], "Z": 0 } }

#AfterBuild:

{
  "MachineCoordinateState": { "X": 100, "Y": 50, "Z": 0 },
  "ProgramXyz": { "X": 100, "Y": 50, "Z": 0 }
}

G91 active on the same block → G53 is ignored per ISO standard; nothing is consumed and no machine-state section is written: #BeforeBuild:

{
  "Parsing": { "Flags": ["G53"], "X": 10 },
  "Positioning": { "Term": "G91" }
}

#AfterBuild:

{
  "Parsing": { "Flags": ["G53"], "X": 10 },
  "Positioning": { "Term": "G91" }
}

Constructors

MachineCoordSelectSyntax()

Initializes a new instance with default settings.

public MachineCoordSelectSyntax()

MachineCoordSelectSyntax(XElement)

Initializes a new instance by deserializing from the given XML element.

public MachineCoordSelectSyntax(XElement src)

Parameters

src XElement

Source XML element.

Properties

Name

Syntax kind name (typically the concrete type name).

public string Name { get; }

Property Value

string

XName

XML element name used to register this syntax with XFactory.

public static string XName { get; }

Property Value

string

Methods

Build(LazyLinkedListNode<SyntaxPiece>, List<INcDependency>, NcDiagnosticProgress)

Build syntax arrangement into the syntaxPieceNode in-place.

public void Build(LazyLinkedListNode<SyntaxPiece> syntaxPieceNode, List<INcDependency> ncDependencyList, NcDiagnosticProgress ncDiagnosticProgress)

Parameters

syntaxPieceNode LazyLinkedListNode<SyntaxPiece>
ncDependencyList List<INcDependency>
ncDiagnosticProgress NcDiagnosticProgress

MakeXmlSource(string, string, bool)

Creates an XML representation of the object. This method may also generate additional resources such as related files.

public XElement MakeXmlSource(string baseDirectory, string relFile, bool exhibitionOnly)

Parameters

baseDirectory string

The base directory for resolving relative paths

relFile string

The relative file path for the XML source

exhibitionOnly bool

if true, the extended file creation is suppressed.

Returns

XElement

An XML element representing the object's state

Remarks

For the demand of easy moving source folder (especially project folder) without configuration file path corruption, the relative file path is applied. The baseDirectory is typically the folder at the nearest configuration file folder. Since the folder can be moving with the configuration file.

Reg(XFactory)

Registers this type's deserializer with the given XFactory (or Default when factory is null). Idempotent.

public static void Reg(XFactory factory = null)

Parameters

factory XFactory
