10.1. Plasma POST Processor Requirements
G Codes
G00 - Rapid move.
G01 - Linear interpolation.
G02 - Circular interpolation (Clockwise). Note: I, J & K value are relevant to the X, Y and Z values. R
for radius and F for feedrate.
G03 - Circular interpolation (Counter Clockwise). Note: I, J & K value are relevant to the X, Y and Z
values. R for radius and F for feedrate.
G04 - Dwell, P value in milliseconds.
G38.2 - Probing cycle used to find the top of the workpiece.
G92 - Temporary Work Offset, used to zero to the top of the workpiece. Used with G38.2 command.
M Codes
M03 - Plasma On, will switch on the output signal to turn on the plasma arc.
M05 - Plasma Off, will switch off the output signal to turn off the plasma arc.
M666 - Turn THC function Off, will switch off the internal THC control logic and during this time the Z
axis position will not be changed by the torch height signals, only gcode commands can change the Z
position.
M667 - Turn THC function On, will switch on the internal THC control logic and during this time the Z
axis position will be changed by the torch height signals. THC will only work when the torch arc is first
switched on via the M3 command.
Important information
Torch touch to trigger switch offset distance is managed by MASSO and is setup during machine
calibration, there is no need to set this value in CAM or POST.
The touch feedrate and machine maximum Z travel during touch to find the top of the material might
be defined in CAM or POST. For example the Z-120 value can be a variable that the user can set as
per the maximum machine Z travel in the torch touch code G38.2 Z-120 F200
Examples
Making a clockwise arc from X10 and Y20 position to X20 and Y10 position:
G01 X10 Y20 F200 G02 X20 Y10 J-10
Finding the top of the workpiece, the below two lines are required to find the top of the workpiece
and then setting the Z offset to 0.00 so that the piercing and cutting heights can be referenced from
this point:
