Resuming Program or Jump to Line

When machining complex jobs such as moulds or detailed engraving, machining times can be very long. A power failure, tool breakage, or interruption may require the job to be restarted.

Restarting a G-code file from the beginning can be time-consuming and waste material.

To solve this, MASSO provides the Resuming Program (Jump to Line) feature, which allows machining to continue from a selected point in the G-code file.

Important Information

Jump to Line is not currently available for Lathe.

MASSO continuously stores the current G-code line number in high-speed internal memory while machining. If power is lost, the last processed line number is retained and can be used to resume machining.

When Jump to Line is used, MASSO moves to the position immediately before the selected line. This ensures that the selected line of G-code is executed correctly when machining resumes.

If the selected start line contains a tool change, MASSO will first prepare the previous tool, then execute the selected line and perform the tool change as required.

WARNING: Jump to Line must not be used to resume toolpaths that use Cutter Compensation, as this may result in unpredictable motion. For compensated toolpaths, machining must be resumed from the start of the compensated section. Cutter compensation is available in Beta software v5.100b or later.

Resuming a Cut Using Jump to Line

Power on the machine if it is turned off.
Home the machine if it was powered off, an E-Stop was used, or position was lost.
Go to the F6 – Load File screen and load the G-code file if it is not already loaded.
Go to the F2 – Program & MDI screen.
Press the button or press CTRL + J on an external keyboard.
The last machined line number will be filled in automatically.
Adjust the line number to a few lines before where machining stopped.
Select and allow MASSO to process the G-code file.
Review the calculated machining parameters carefully.
Press to proceed.
The Z axis will move to the Home position and the X axis will move to its starting position.
Press Cycle Start after each axis movement and confirm the axis has moved to the correct position.
The final axis to move into position will be the Z axis.
Machining will resume after the final Cycle Start.

Power on your machine if the machine is off
Home the Machine if the machine was powered off, the E-Stop was used or you have lost position.

Resuming from the G-Code Editor (MASSO G3 & MASSO Touch)

Go to the F6 – Load File screen and press Edit to open the G-code editor.
Scroll to the line you want to start from and place the cursor on that line.
Press
MASSO will close the editor and open the Jump to Line screen with the line number pre-filled.
Select and allow MASSO to process the file.
Review the displayed parameters carefully.
Press to proceed.
The Z axis will move to Home and the X axis will move to its starting position.
Press Cycle Start after each axis move and confirm correct positioning.
The final axis to move into position will be the Z axis.

INFORMATION: If the selected line contains a tool change, MASSO will prepare the previous tool before executing the selected line and completing the tool change.
