This configuration shows how to configure a standard Mach3 Plasma profile.
STEP 1:Start by making a backup of the existing installation:
Make a backup of the configuration and file installation, we recommend creating a backup of the current installation by right-clicking in the current installation folder and zipping it.
STEP 2: Configure Mach3 and ESS Plugin according to the screenshots below or download and install this XML.
You will need to install the screen found in the download folder and place the macro in the macros directory for the profile folder.
View/Load Screen:
STEP 5: Configurations Screen
PIERCE DELAY
Torch motion starts the number of seconds you set as DT after the ARC signal is determined. This can be a value between 0.1 to 9.9 seconds.
HEIGHT
Set the height.
CUT HEIGHT
Set the Cut height.
OFF SET_Z
Set the OFF SET_Z of the switch of a floating head as a probe when using a probe signal to determine the material position.
Z Top Set the safety height, the Z axis will move to this height with the M2015 macro for ending the cut.
Probing FR
Set the velocity/FeedRate at which the probing is executed.
Z Min Height
Set the travel height when probing.
STEP 6: Macros:
M03: Probes, does the initial pierce, and sets the head at the cutting height:
Run G31 Z “Z min. height” F “Probing FR”
Move the Z Offset Z and set Z0
Move the Z Height
Torch on
Wait for Pierce_Delay
Move the Z Cut_Height
Activate THC
M05: Ends cutting.
Torch Off
Deactivate THC
Move Z to Z_Top
M62: Start Cutting.
Torch On
M63: Ends Cutting.
Torch Off
STEP 7: Test the Wiring and Configuration:
Press the knob three times to enter test mode in the THC and observe the ARC OK signal activate.
Turn the knob up or down to move the axis and observe the Torch UP and Torch Down LEDs activate when moving in each direction. The Z-Axis should also move to adjust the position.
To exit test mode, press the knob once.
RECOMMENDATIONS:
If the height adjustment is not smooth or overshoots the position, lower the % of correction speed.
Make sure MACH3 is properly licensed, and THC does not work on DEMO Mode.
If you do not see action on the signals coming from the THC, try tracing them by measuring them at the output of the THC, the input of the breakout board, the LEDs of the breakout board, the Software Diagnostics, the software function, etc... You need to understand where you are losing them.
This post processor does not use the M3 and M5 macros or the parameters set on the screen but sends all the actions via gcode and starts and stops the plasma using the M62 and M63 macros.
The variable for the post-processor will need to be set up as internal variables:
switchoffset = Z Offset
zminheight = Zmin. height
probingfr = Probing FR
OVERVIEW:
The function of these instructions is to show the operation of the postprocessor for sheet cam with Z for MACH3
STEP 1:
Load the postprocessor to be used: Select the "MACH3 CNC4pc plasma with Z" postprocessor in Options/Machine.
STEP 2:
Click on "Set a post-processor variable".
STEP 3:
Enter the values of the variables to be used on probing: Steps 2 and 3 may need to be repeated for each variable. these can be: switchoffset (offset of the floating head switch), zminheight (how low the Z axis goes while probing), and probingfr (Velocity at which probing will be executed).
STEP 4:
Create Cut Feature: After having entered all the variables, we proceed to do the cutting operation.
