MASSO offers three methods to recover your cut after your Plasma machine has stopped.
It is important to choose the correct type or resume that suits the situation

• Plasma fails to ignite at the start of a cut
• You want to start the cut at a point partway through the Gcode file
• The machine stops part way through a cut and needs to restart.

 Restart after Plasma fails to ignite.

This is the easiest to recover from.
After probing the Plasma torch rises to piercing height and the torch ignites.
If it fails to ignite you will receive a No Arc OK alarm and the machine will stop.
 

Retry

• Press Cycle Start to resume.
• The Plasma will probe the material and resume the cut.

Starting part way through a Gcode file

There may be several reasons that you want to start part way through a Gcode file. 
For example you may not have time and wish to continue the job the next day .
This method is used where the cut has not already begun

• Enter the line number that you wish to start from and press the Start from Line button
• MASSO will search backward through the Gcode file and find the last M3 Gcode command and start from this line.

• The starting point will be indicated on the MASSO screen.
• If this is not the correct toolpath yo wish to cut then enter a new line number and press Start from Line again
• Once the correct starting position is shown press Run to begin.
• Press Cycle start to move the Axes one at a time to the starting point.
• Once the Torch is over the start position press cycle start and the torch will probe and start the cut as normal.
