Program Playback

After recording a laser measurement program, you can play it back to let Easson2D automatically perform laser measurement according to the recorded measurement steps and movement route.

During playback, the software executes each measurement step in the recorded order and moves to the corresponding positions to complete laser point acquisition.

Play a Recorded Program

Select a recorded laser measurement program and start playback.

Easson2D executes the program in the recorded order, for example:

Move to the measurement position → perform laser measurement → move to the next position → continue measuring

If the program contains multiple laser measurement items, the software completes the entire measurement workflow step by step in the recorded order.

Move Along the Recorded Route

During playback, the machine moves in sequence according to the positions saved during recording.

If you added waypoints with Set Path while recording, these waypoints are also executed in their original order.

For example, if you recorded:

Measurement position A → Waypoint 1 → Waypoint 2 → Measurement position B

the machine also moves along the same route during playback.

Therefore, "Set Path" is not only used for route planning during recording, but also directly affects the actual movement trajectory of the machine during program playback.

The Program Does Not Avoid Obstacles Automatically

Easson2D executes the program according to the recorded positions and waypoints, but it does not automatically detect whether new obstacles appear between two positions.

Therefore, before playing back a program, confirm that:

• The workpiece is placed in the correct position
• The fixture position matches the one used during recording
• No new obstacles are present in the measurement area
• The set waypoints are still safe
• The laser head and machine moving parts will not collide with the workpiece or fixture

If the workpiece or fixture position changes noticeably, recheck whether the original program route still applies.

Watch the Laser Measurement Range

When the program reaches a laser measurement position, make sure the measured surface is within the range that the laser sensor can detect normally.

If the program contains measurement steps that require Zero Return, also make sure there is a detectable workpiece surface under the laser head.

If the actual workpiece height or placement changes noticeably from when the program was recorded, laser zero return and subsequent point acquisition may be affected.

First Playback of a New Program

For a laser program that has just been recorded, it is recommended to watch the entire run carefully during the first playback.

Confirm that:

• Each measurement step is executed in the correct order
• The machine reaches every measurement position correctly
• The waypoints are executed as expected
• There is no collision risk during machine movement
• The laser measurement positions are within the normal detection range
• Each laser measurement step completes normally

Only after confirming that the program runs normally, use it for subsequent repeated measurement.

Repeated Measurement

Once the program is confirmed to be correct, it can be used to repeatedly measure identical workpieces.

The basic workflow is:

Place the workpiece → Play back the laser measurement program → The machine moves along the recorded route → Each laser measurement step is executed automatically → Measurement results are generated

This reduces the need for the operator to repeatedly move the machine and acquire points manually, improving the efficiency of repeated measurement.

Usage Notes

Automatic execution of a laser program relies on the following items established during recording:

Measurement steps + measurement positions + a safe movement route

Therefore, if the workpiece position, fixture position, or measurement environment changes, first confirm that the original program still applies before running it automatically.

For programs whose measurement steps or waypoints have just been modified, it is also recommended to check the complete run route once more before using them for formal batch measurement.
