What is Jog Back?

Jog Back is a feature that allows the user to move the spindle or tool head out of the way to inspect the workpiece or the cutter, and then automatically return to the previous machining position.

Jog Back becomes active after a G-code file is loaded or when the machine is placed into Feed Hold. No manual setup is required.

How Jog Back Works

When you jog the machine, MASSO records the axis positions at the moment jogging begins.

When Cycle Start is pressed to resume machining, MASSO moves each axis back to its original position one at a time.

Only the axes that were moved during jogging will Jog Back.
For example, if only the X and Z axes were jogged, only those axes will return.

Each press of the Cycle Start button moves one axis back to its previous position.
If three axes were moved, three presses of Cycle Start are required to fully return to the original position.

The Jog Back order is: X , Y , A ,B , Z

Jog Back During Feed Hold

If the machine is in Feed Hold, pressing Cycle Start will Jog Back one axis at a time.

Once all axes have returned to their original positions, pressing Cycle Start again will resume machining.

Cancelling Jog Back

Jog Back is cancelled under the following conditions:

• A new G-code file is loaded.

• The Rewind button is pressed.

   

Any jogging movements made after loading a G-code file or pressing Rewind will create a new Jog Back sequence.
