License Agreement

Before using the “ArcPro v2 Plasma Control” package and accompanying software tools, please take a moment to

go thru this License agreement. Any use of this hardware and software indicate your acceptance to this

agreement.

It is the nature of all machine tools that they are dangerous devices. In order to be permitted to use the “ArcPro v2

Plasma Control” package on any machine you must agree to the following license:

I agree that no-one other than the owner of this machine, will, under any circumstances be responsible, for the

operation, safety, and use of this machine. I agree there is no situation under which I would consider Vital Systems,

or any of its distributors to be responsible for any losses, damages, or other misfortunes suffered through the use

of the “ArcPro v2 Plasma Control” package and any accompanying software. I understand that the “ArcPro v2

Plasma Control” package is very complex, and though the engineers make every effort to achieve a bug free

environment, that I will hold no-one other than myself responsible for mistakes, errors, material loss, personal

damages, secondary damages, faults or errors of any kind, caused by any circumstance, any bugs, or any undesired

response by the board and its software while running my machine or device.

I fully accept all responsibility for the operation of this machine while under the control of the “ArcPro v2 Plasma

Control” package, and for its operation by others who may use the machine. It is my responsibility to warn any

others who may operate any device under the control of the “ArcPro v2 Plasma Control” package of the limitations

so imposed.

I fully accept the above statements, and I will comply at all times with standard operating procedures and safety

requirements pertinent to my area or country, and will endeavor to ensure the safety of all operators, as well as

Introduction

IMPORTANT

This document makes the assumption that the reader has

thoroughly reviewed the necessary documentation:

Mach4 HiCON Integration Manual

User Manual for HiCON Integra or Mini Motion Controller

Has completed the proper hardware setup, and possesses basic

knowledge and understanding of Mach4 CNC Software.

This document DOES NOT serve as a primer or tutorial for the

use of Mach4. As such, readers without basic understanding of

Mach4, and other software components not associated with

Vital System Inc. are advised to consult the appropriate user

manual and/or software vendor.

This document only serves as a supplemental user guide for the

additional setup of integrating Torch Height Control with the

HiCON and Mach4.

NOTE:Several notes such as this can be found throughout this document which

list key points and comments worth remembering.

Wiring Diagrams

Plasma Electrical Noise Filter for Digitize Sensor (Mini)

Connecting NPN Digitize Sensor (Ohmic Probe)

NOTE: It is highly recommended to follow the circuit diagram below when

using a Digitize sensor on the torch head. Because a Plasma Torch uses high-

voltage for cutting, voltage spikes and electrical noise must be properly filtered

in order to safely connect the sensor to a digitize input on the HiCON Mini.

Importing Mach4 Profile

Download the latest ArcPro Plasma profile available on the sidebar from the product website:

http://www.vitalsystem.com/arcpro

Open Mach4 loader and click on Import Profile. Browse for the downloaded profile (.m4prof) file and click Open. If

you wish to rename the imported profile, change the name and click OK. Otherwise, press OK to finish.

Mach4 I/O Configuration

Plasma Cut Sequence

The typical plasma cut sequence starts with a probe to locate the material. After the probe is complete, the torch is

raised to ignition height and torch is turned on and wait until the Arc OK (Ok to move) signal is detected. Once the

Arc OK signal is found, the Z axis moves to the pierce height and the pierce delay starts. Immediately following the

pierce delay, the XY motion starts and the torch height control begins once the THC delay expires.

All these steps are done by the M3 Macro script provided in the Mach4 Plasma Screen.

The following Gcode shows how a typical plasma cut sequence can be programmed:

M3 (Probe the material, move to ignition height, turn torch on, wait for Arc Ok, move to pierce height, wait for pierce delay)

G0 X5Y5 (Begin XY motion, at the same time wait for THC delay then Z- axis starts to follow the material height)

G0 X10Y10

M5 (end torch height control sequence)

Step 1:

The height that the Z-Axis was at when the cut sequence began.

Step 2:

The torch head comes down to contact the material to determine the material height

(probe).

Step 3:

The torch head lifts to ignition height and turns on.

Step 4:

The Arc Ok signal is detected and the torch moves to pierce height.

Step 5:

Torch waits for pierce delay to complete and XY motion begins. THC delay timer is

started.

Step 6:

THC delay is complete and the THC takes over Z-Axis control
