Program Recording

Easson2D probe measurement also supports program recording.

Like vision measurement programs, probe programs use automatic recording. You do not need to write each program step manually. Simply complete a probe measurement following the normal workflow, and Easson2D automatically records the corresponding operations and generates the program steps.

Therefore, the basic workflow remains:

Complete a correct measurement → automatically generate the program → repeat the run later

Measure as You Record

During program recording, you can use the probe in the normal way to perform:

• Point measurement
• Line measurement
• Circle measurement
• Height measurement
• Flatness measurement
• Cylinder measurement

Each time the probe contacts the workpiece and acquires a measurement point, Easson2D records the position of that probe point.

After the measurement is complete, the corresponding probe measurement steps are automatically added to the program.

How Probe Programs Move

Probe programs have one very important difference from ordinary vision measurement programs:

The program records the position of every probe touch point, and when the program is run again, it moves the probe to these positions in sequence.

Between two consecutive recorded positions, the machine positions itself along a straight-line path.

For example, if the program records in sequence:

Position A → Position B → Position C

When running, the probe moves in the same order:

A → B → C

Watch the Probe Movement Path

Easson2D executes probe movement according to the recorded positions, but the program cannot automatically detect whether obstacles exist between two positions.

Therefore, if the following exist between position A and position B:

• Workpiece bosses
• Fixtures
• Screws
• Workpiece side walls
• Other protruding structures

Even if both measurement positions A and B are correct, the probe may collide with obstacles in between when moving directly from A to B in a straight line.

Therefore, when recording a probe program, you must consider both:

Whether the measurement points are correct + whether the movement path between two consecutive positions is safe.

Add Waypoints with "Set Path"

If two probe measurement positions cannot be reached by a direct straight-line move, you can click:

Set Path

during program recording to add one or more intermediate waypoints.

For example, the normal recording is:

Measurement point A → Measurement point B

But when an obstacle exists between A and B, you can change it to:

Measurement point A → Waypoint 1 → Waypoint 2 → Measurement point B

This lets the probe first move to a safe position, then move around the obstacle to reach the next measurement position.

Waypoints are mainly used for planning the probe movement route and do not need to be actual measurement points.

Route Planning Principles

When recording a probe program, ensure that:

Any two consecutive program positions can be reached safely along a straight line.

If not, add waypoints using "Set Path".

Pay special attention to the following when planning the route:

• Raised areas on the workpiece
• Steps of different heights
• Fixtures and clamps
• Workpiece side walls
• Areas the probe ball and stylus may pass through

Do not only check whether the probe ball can ultimately reach the measurement point; also consider whether the probe and stylus have enough clearance throughout the entire movement.

Recommended Recording Approach

For workpieces with a more complex structure, the following recording approach is recommended:

1. Move the probe to a safe position.
2. Enter the area to be measured.
3. Perform the probe point acquisition for that area.
4. If there are obstacles between this area and the next measurement area, first use "Set Path" to add safe waypoints.
5. Move to the next measurement area and continue measuring.
6. Complete the measurement workflow for the entire workpiece.

You can think of the recording process as:

Measurement steps + a safe movement route

Together, these two parts form a complete probe measurement program.

Pre-Run Check

The probe is a contact-type measuring device, so when running a newly recorded program for the first time, pay special attention to the movement route that has been planned.

It is recommended to confirm:

• The measurement point order is correct
• The waypoint positions are correct
• There are no obstacles between two consecutive positions
• The probe will not hit the fixture or other areas of the workpiece
• The entire measurement route has sufficient safe clearance

A probe program does not actively detect and avoid obstacles on its own, so a safe movement route must be planned by the operator in advance during program recording.
