Entry / exit

These properties apply to both entry and exit.

Enter / exit at midpoint

Closed loop overlap

Use entry parameters for exit

Entry

Type

Defines lead-in geometry.

• Perpendicular line
  Entry will be a line perpendicular to the next entity. For linear leads on arc entities, this will be the line perpendicular to the tangent line of the arc.
  For linear leads, the angle of a lead-in is defined with respect to the first motion after the lead. A 0° lead-in will lead straight into the first cut. Positive lead-in angles are defined clockwise from the 0° position, so a 90° lead-in will cause a sharp left-turn into the first cut. Lead-out angles are defined in a similar fashion with a 0° lead-out extending straight out of the last cut. Positive lead-out angles are defined counter-clockwise from the 0° position, so a 90° lead-out will cause a sharp left-turn out of the last cut.

  For arc leads, angle defines the distance the lead will extend around a circle. A 90° lead would extend one quarter of the way around, whereas a 180° lead would extend half way around - forming a semicircle.

• Tangent line
  Entry will be a line tangent to the next entity on the profile. Useful in cases where lead-in is on a convex profile. Also good for exteriors?

• (show tangent on straight entry or exit, show tangent on exterior lead)

• Arc
  Entry will be an arc motion, tangent to the . Use Arc radius and Arc sweep angle to control size of the lead-in.

• Line and arc
  Arc lead-in with linear extension at start of lead-in.

Side

Equivalent to ‘flip leads’. Can be used to correct situations where leads are placed on the wrong side of a profile.

Height / ramp

I don’t know what this does.

Arc radius

For arc style lead-ins or lead-outs, this is the radius of the arc. Use this to control the size of the entry or exit.

Arc sweep angle

For arc style leads, this is used to control the arc length.

Line length

Used with linear lead-ins, defines length in mm of entry motion.

Extend / shorten path

Undertravel or Overtravel. Use a negative value for undertravel, to shorten the length of the path by some distance. Enter a positive value

Leave at zero to keep original path with no shortening or extending.

Mention the setting in Parameters for Projection to control how the healed surface is used for interiors.

Does RM distinguish between interior and exterior profiles for leads?

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 orientation, as defined in Fanning distance.

...

When disabled, 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 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.

...

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