Touch Sensor and Plasma Torch Height Control Configuration for Mach4
There are two ways of commanding the plasma cutting sequence. You could command all the actions using gcode commands (M62/M63 as torch on/off, G31 for probing, and G4 for piercing delays) or you could set all the operating parameters and just command the plasma using the 2003/M2005 macros. These instructions will configure the system to use it both ways.
M2003 Macro performs the following actions:
Probes or moves down the Z axis to the "Z Min. height" position that is set in the DRO for this value and the feed that is set in "Probing FR".
Set the current position to be the new Z = Zero considering the Z Offset if a Floating Head is used.
Moves the Z up at max velocity to the piercing position or DRO = Pierce Height.
Turn on the Torch.
Wait for Pierce time or DRO = Pierce Delay.
Moves the Z up at max velocity to the cut position or DRO = Cut Height.
M2005 Macro performs the following actions:
Turns the torch off.
Deactivates the THC.
Moves the Z axis at max speed to the position where it would be safe to move at max velocity to the next cutting position. This is DRO =Z Top.
The screen holds the new DRO values and also has the code that will enable the probe while the system is probing.
