Woodworking engraving machine knife is divided into two kinds, one: a long time carving high hardness material tool wear and broken edge is inevitable, the tool wears, the depth of the sculpture can not reach the set requirements; two kinds: It is a very real problem to break the blade, replace it with a new one, and ensure that the two tools are as high as each other.

        These two common phenomena can be categorized as a problem. It can be understood that a situation where the tool wear is severe is equivalent to a broken edge condition. We can handle it in the same way. When we find that the tool suddenly breaks during the operation of the woodworking engraving machine, suspend or stop the operation in time. Then note the current block number, which is used later. After the spindle is completely stopped, replace it with a new tool. Because we are manually changing the tool, this will inevitably lead to a change in the height of the Z direction. We only need to use the counter block to re-determine the origin in the Z direction. There is no change in the X and Y directions. We don't need to control it. After the determination is complete, we find the "Advanced Start" function under the operation menu. The dialog box asks us to enter the starting line segment number. This segment number is the number we wrote down when we stopped the machine. We need to input the starting line number. The number is smaller than the number you wrote down, and the specific number depends on how long we found the broken knife. If you find a late night, you will lose some more. The end of the default segment number can end. In this way, the woodworking engraving machine can automatically continue the engraving on the unfinished part.
