The fixation of woodworking carving machines usually requires the following steps:

1. Place the engraving machine on a flat surface to ensure its stability.

2. Use anchor screws to secure the engraving machine to the workbench, ensuring that it does not move.

3. Use a spirit level to check if the engraving machine is level. If it is not level, adjust the foot screws.

4. Use fixtures to fix the workpiece on the worktable of the engraving machine, ensuring that the workpiece does not move.

5. Before starting carving, check again whether the carving machine and workpiece are stable to ensure carving quality.

The above steps can help ensure the stability and accuracy of the woodworking carving machine, thereby improving the carving effect.
