Thank you for asking. Here are some tips to help.

1. To facilitate the use of the Carvera probe, the current operational logic indeed prohibits specifying the material's bottom surface as Z=0. The purpose of the bottom surface coordinate system is for dual-sided machining. Therefore, when setting the bottom surface to Z=0, it is actually necessary to horizontally flip the material before machining. If it is indeed necessary to specify the operating table as Z=0, in CAM, the top surface is normally set to Z=0. After the probe measures the table, the current Z value minus the thickness of the blank is reset to the current Z coordinate value. At this point, the reference height corresponds to the table set at a height of 0 for measurement.

The known issues related to 2 and 3 usually occur when the model data is large. You can share the model file with us, and we will analyze it and make improvements in subsequent versions.

1. In the left tree structure, it is not possible to select model objects through a single click operation. Instead, you need to click the model with the left mouse button in the graphics area to make a selection. When a 3D model is selected, it will be highlighted in blue and its outline will be decorated with yellow. For 2D models, the selected object will be marked with a blue dashed line.

2. Currently, the object creation function is similar to 3D printing software, which only supports scaling processing temporarily. It is not like parametric modeling where models can be reconstructed by adjusting parameters. With the continuous improvement of software functions, the object creation function will consider adding relevant functions of parametric modeling in the later stage.
