15. Configure motors, encoders and limit switches in software
5. Configuring motors to move in the correct direction
It is important to understand that
correct motor direction is determined by the motion of the tool relative to the part, this is not
necessarily the same as the motion of the table. For axes that move the table while the tool
remains stationary such as the X & Y axes on a typical Bridgeport type knee mill, the table
motion is the opposite of the “tool motion”. For axes that move the tool, such as the quill on
a knee mill, axis motion is the same as the tool motion. The illustrations below describe this
concept.
Correct tool motion for each axis
Difference between table motion and tool motion on X axis of knee mill
In the above illustration, the tool is moving in the X+ direction relative to the part
while the table moves to the left.
