INFORMATION: If you are using a G3 controller for Plasma and are wishing to purchase a torch height controller unit you may wish to consider the MASSO DTHC which is specially designed to integrate into the MASSO Controller.
MASSO supports THC control signals to easily connect different types of THC units. THC units that are designed to control the Z-axis directly using STEP and DIRECTION signals are not supported.
Control Signals
Plasma Arc OK Signal
This signal is required to tell MASSO that the arc has been successful.
This signal should go HIGH from the THC on a successful arc start.
Wire this to one of the inputs on MASSO and assign the input as Plasma Arc OK Signal.
Z Up Signal
When this signal goes HIGH, the Z-axis moves up.
Wire this to one of the inputs on MASSO and assign the input as THC-1.
Z Down Signal
When this signal goes HIGH, the Z-axis moves down.
Wire this to one of the inputs on MASSO and assign the input as THC-2.
PROMA 150 Wiring Example
Setting up MASSO G3 and MASSO Touch with Proma Compact THC 150
Enable the Plasma Torch option in Multi-head settings and leave the MASSO DTHC software module required box unticked, otherwise it will not work.
You can leave X, Y, and Z offsets at 0 if you are using a standalone plasma machine.
The Torch Touch Offset value is used to compensate for the difference in torch height relative to the touch-off switch. This value is not used for Ohmic touch.
Wire the THC to MASSO as shown in the wiring example above.
Remember to invert inputs as needed so they show LOW when not active, for example Plasma-Arc OK, THC-Up, and THC-Down.
Inputs can be inverted by selecting the input and pressing the spacebar.
All inputs and outputs change to HIGH when active.
Enable Plasma
Enable Plasma and ensure the MASSO DTHC software module is disabled.
Assigning THC Inputs
Assign the required THC inputs.
Assign other Inputs
Assign any additional required inputs.
Assigning Plasma Outputs
Assign plasma outputs as needed.
The G200 G-code command is the standard for MASSO G3 plasma use from Version 5 software. Please read the G200 documentation carefully, as it is important to understand this command structure and how to use it correctly.
G200
G200 defines how your plasma will operate.
A G200 command with no parameters will turn off G200 operation and the plasma will operate in legacy mode, where all operations must be completed manually using G-code.
For information on using G200, refer to the relevant documentation - HERE
Post Processors for Version 5 Software
Post processors have been developed to work with MASSO Version 5 software.
These post processors are suitable for all plasma THC units or for plasma systems without THC.
Please read the information provided in the G200 G-code documentation to understand how it works.
