Entry / exit

These properties apply to both entry and exit.

Enter / exit at midpoint

On a closed path, this moves the entry / exit point to the midpoint of the path’s first segment.

Closed loop overlap

On a closed path, this extends the start and end of the path to cause an overlap. Only positive values are permitted.

Use entry parameters for exit

Uses entry values as the exit parameters. The Exit option must also be enabled to use this option.

Entry and exit parameters

Type

Defines entry or exit geometry.

• Perpendicular line
  Entry or exit will be a line perpendicular to the base toolpath at the intersection point of the entry / exit and toolpath.

  Image Removed

• Tangent line
  Entry or exit will be a line tangent to the base toolpath at the intersection point of the entry / exit and toolpath. This is useful for entry or exit on a convex curved toolpath or where the entry or exit should be aligned with the toolpath.

  Image Removed

• Arc
  Entry or exit will be an arc motion, tangent to the base toolpath at the intersection point of the entry / exit and toolpath. Use Arc radius and Arc sweep angle to control size of the arc.

• Line and arc
  Arc entry or exit with linear extension added.

Side

Entry and exit motions can be placed on the right or left side of a path. You can use this setting to correct situations where entry or exit motions are placed on the wrong side of a path.

...

Height / ramp

Create an incline on an entry or exit motion. Ramp height is the offset distance from the original start point of the entry or exit, along the approach vector.

...

Ramp height can also be used with Arc entry or exit paths.

Additional angle

Only available for linear entry / exit types (Perpendicular or Tangent). This adjusts the entry or exit path by a specified angle.

...

Arc radius

For Arc entry or exit paths, this is the radius of the arc. Use this to control the size of the entry or exit.

...

Arc sweep angle

For arc entry or exit paths, this is the angular distance the arc sweeps from the connecting point on the tool path.

...

Line length

Used with linear entry or exit, defines length in mm of entry or exit motion. Negative values are not permitted.

...

Extend / shorten path

A positive value will extend the base toolpath by adding a line tangent to the path, at the intersection of the entry / exit. The effect would be to move the entry or exit past the intersection point, creating an overlap.

...

A negative value will move the entry / exit back from the intersection point, leaving undertravel or a gap in the base toolpath.

...

Note that on curved toolpaths, the extension follows a tangent line, it does not follow contour of the toolpath.

...

Normalize direction

...

Normalize direction

When enabled, the tool axis control vector of approach will be perpendicular to the healed surface geometry, at the start of the entry. This will ensure that the pierce occurs with the plasma torch perpendicular to the workpiece. After piercing, the tool axis control vector gradually transitions to the cut path vectororientation, as defined with in Fanning distance.

...

When cleareddisabled, the vector of approach will be parallel to the cut path vector.

Note that using Normalize direction requires that the Projection option (on the Path Parameters page for plasma cutting) is set to Automatic or one of the other options that will create “healed” CAD geometry in Robotmaster.

Fanning distance

...

When the Normalize direction option is enabled, Fanning distance controls the distance length of the transition from the initial pierce tool axis control vector orientation until the entry or exit vector is parallel to the cut path vector.(image)

...

Set this to Automatic to transition gradually along the entire length of the entry or exit.
