Problem Description

        There may be burns on parts end near the section in actual production, for example:

        As shown in the picture, the burn occurs near right cut-off line, which means the laser beam burns it during part’s falling when the last cutting path is finished. According to the factors above, we provide three methods to solve it.

1. Adjust Slow Stop Parameters

       In TubePro, Layer, you can enable Slow Stop process to set specific cutting parameters for cutting path near the part end.

        Slow Lead: The distance applied this special parameters.

        Speed: Cutting speed for this section.

        Precise Adjust: Enable it to adjust Duty Cycle and Frequency for this section of cutting path.

2. Add Leadouts

        You’re allowed to apply Leadouts Process on right cut-off line of the parts, but if the parts are Co-Edged during the nesting, Leadouts process will get invalidated on co-edged cut-off lines, you’d better try other methods to solve the burns.

3. Add Gap

        You can also add proper Gap on the cut-off line to get this effect eased.

4. Adjust Cutting Parameters

        Modify the Power Curve in Layer Parameters appropriately, for example, you can lower the laser power when the machine is at a relative low speed of cutting.
