1. General information
Before using this machine, you must first read and understand the operating instructions completely.
This manual contains important information regarding the proper installation, operation and maintenance of
the equipment described herein. There are several risks of injury or property damage associated with the use
of any CNC cutting table. Anyone who comes into contact with the installation, maintenance or operation of
the CNC cutting table must be fully familiar with the contents of this manual. To protect yourself from
personal injury or property damage, follow the following directions and instructions in this manual.
Every PRITEC CNC cutting table is produced in accordance with the Machinery Directive 2006/42/EC. A manual
including maintenance overview is supplied with every CNC cutting table. These must be kept and maintained
properly.
Because continuous improvements are made to the equipment with a view to quality, PRITEC reserves the right to
change specifications of the equipment described in the manual.
1.1 Introduction
This manual will help you get started with using your PRITEC ACROS. Read the manual carefully so that you can make
full use of your cutting table and cut the most fantastic products.
1.2 How does the process work?
The table has a control program called Mach3 CNC controller. You can install this program on your laptop by
following the steps in this guide. With this program you can 'manually' control the machine with your laptop.
If you want to automatically cut out a workpiece, you can load a G-code into the control program and then let it play
back.
1.3 What is G code?
G-code is a command used when programming a CNC program .
This G code is an instruction for the machine. The code has a structure with the letter G, followed by a number, for
example G26. The number after the G has a meaning. The numbers 0 to 99 have a fixed meaning that is laid down in
an ISO standard. A G-code tells the machine what to do, in what order, with which tools, in which location and at
what speed and feed.
Not only G codes are important in a CNC program. M codes are also used. These machine auxiliary codes are as
important as the G codes themselves. A G code is used when machining a workpiece, while M codes are used more
as a supplement to give the machine additional instructions, for example M03 or M05. These codes are used, among
other things, to switch the plasma cutter head on or off. The use of these codes is not the only important thing about
a CNC program. The program is largely dependent on coordinates and values that determine the accuracy and
correctness of a workpiece.

3
1. 4 How do I create G-code?
To create G-code you need a program that allows you to create a 2D or 3D file. This file contains the geometry of the
workpiece to be cut. In general you can create this with 2D or 3D drawing software. You then need a program to
convert the geometry into a G-code that the machine can read. Sometimes both processes can be performed with
the same program. Check out our site for the possibilities https://www.pritec-automation.com
2. Safety regulations
2.1 Basic principle of safety in the workplace
Most accidents occur because safety regulations are not taken into account or are ignored. Safety equipment
such as shields, safety glasses, dust masks, hearing protection, etc. reduce the risk of accidents. But even the
best safety measures provide no protection in the event of poor judgment, inattention or carelessness. Pay
attention at all times in the workshop and use common sense. If something seems too dangerous, don't try it,
but find a safer solution, even if it may take more time. Remember: your personal safety is your own
responsibility.
The user of the machine must be sure of the following:
Persons operating the machine have received instructions/training and have been made aware of the dangers and
safety regulations.
The safety regulations are complied with and can preferably be read at the workplace. For this reason, the manual
is part of the machine and must be kept within easy reach of the machine at all times. When the machine is resold,
the manual must be handed over!

5.1 Transport and storage
Transporting material
When loading/unloading or transporting the equipment at the workplace, you must use suitable transport and
lifting equipment (e.g. crane/forklift, truck). Ensure that components are lifted and transported carefully so
that they cannot fall, taking into account package size, weight, center of gravity and fragile parts. Use a forklift
or pallet truck to transport the package (figure 1).
When the machine is out of the packaging, use a lifting strap or round
sling to transport the machine (figure 2).
Storage and stacking of packages
Packages containing the machine should be stored in a covered area, out of
direct sunlight and low humidity, at a temperature between -10°C and 40°C.
Stack a maximum of 3 packages on top of each other.
Unpack
When the machine is delivered, immediately check the package for possible damage due to transport and
storage. Check that the contents of the package are complete using the parts list and drawing. In case of
damage during transport, the customer must immediately inform the transport company. Packages should be
opened with attention to safety, keep a safe distance when opening tires and be careful not to let any parts
fall out of the package during opening.

6. Software installation
For this installation you will need a laptop that has the correct specifications to run the software. (see 4.2 minimum
laptop specifications)
After installation, we recommend that you use the laptop's power cable as a power source instead of the laptop
battery when operating the ACROS.
6.1 Installation software for PRITEC ACROS control
Download operating software
The plasma table is controlled by so-called “control software”. The software is freely accessible and easy to
download via the website. The latest version of the operating software can be found at https://pritec-
automation.com/pages/downloads . This page explains where and how you can download the software.
Perform the installation
NB! Windows may ask you to enter an administrator password. This is caused by the installation program that
installs a driver to establish the connection with the plasma cutting table. This driver is important for the functioning
of the plasma cutting table and it will not be able to communicate with the computer if it is not installed.
A screenshot of the installer starting up.
After this screen, the installation of the Mach3 software starts. The installation of Mach3 must be completed step by
step to ensure that the product functions properly.

12
A screenshot of the Mach3 software installation welcome screen.
The installer recommends closing all Windows applications before the installation begins. Once this has been done,
click Next .
Read the following text carefully . Make sure the text is understood and then click Yes . If it is not agreed, click No .

13
Click Next .
Attention ! Make sure that Mach3 is always installed in C:\Mach3 . This is important for the correct installation of
the program. This is because the installer assumes that Mach3 is installed in C:\Mach3 to copy the profiles of the
machines.

14
Click Next .
This screen is not important for the installation itself, but can help keep your computer organized. You can enter
whatever you want here.
Click Next .

15
This is the final step before installing the software. Click Next .
This screen shows which files are being copied. Typically, installation takes no longer than three minutes. Do not
close the program if it takes longer.

16
The installation notes that external components have been successfully installed. Click OK .
This last screen shows the completion of the installation. After a short moment of patience, you will automatically
switch to the next screen.
Mach3 installation is complete! This menu offers the option to install additional components for the program. It has
been decided not to install any other profiles ( XMLs ) that come with the program and LazyCam will not be installed
either.
Load Mach3 driver is an option to immediately check whether the table can connect to the computer. If you are just
installing the software and the table is not connected to the computer at the time, you will see the following screen.
If the table is connected to the computer, the connection is tested.

17
This final screen confirms the completion of the installation. The profiles have been copied, shortcuts created and
the program is ready to use. Click Close .
6.2 Installing software to write G-code
Generating a machine code (G-code) can be done using various programs. You may already have the right software
for this. If not, look for the options at https://pritec-automation.com/pages/kennis-artikelen
7. Start-up
1. Connect the USB cable to the control box and to your laptop.
2. Plug the power cable into the control box and switch on the red switch.
3. Open Mach3 CNC Controller and click on the blue RESET icon after startup. Make sure the emergency stop is
turned off. The ACROS can now be operated using the arrow keys on your keyboard (Z = Page Up/Page
Down). Use the space key on your keyboard to have the machine automatically return to its home position.
The machine will search for the home switches one by one.

18
7.1 Set workpiece zero point
When you create a g-code, a zero point (reference point) is created. This is the starting point of the process. You can
set a zero point at any point on the table.
Figure 5 example zero point
1. Control the plasma head to the desired zero point position
2. See figure 4 number 4. Make sure the red LED indicator is turned off so that the zero point coordinates are
visible. Not the machine coordinates.
3. Now click on the X,Y and Z ZERO (see figure 4 number 2.) or click on ''zero all''. All three positions have now
switched to zero. The zero point position has now been determined.
4. If you want to return to this position, click on ''GO TO XYZ 0'' (see figure 4 number 3.)

19
7 . 2 Testing
NB! Make sure the table is level before you start testing.
1. Make sure the air compressor and plasma cutter are turned off .
2. Open a test file from the downloads page on our site.
3. Place a plate on the table.
4. Drive the machine to the desired position where you want to start cutting (see chapter 7.2). Make sure there
is enough space. To be on the safe side, steer towards the center of the plate so that there is at least 150
mm available on all sides.
5. “ZERO'' the X, Y and Z axis by clicking on the blue icons (the red lamp indication will turn green). ''ZERO'' is a
reference point so that the machine knows its position. You can set this anywhere you want. Make sure that
you set this point to the correct position due to the size of the workpiece to be cut out. You must prevent
the machine from cutting beyond its table limit.
6. Press the play icon. The machine will now play the G-code file.
7. If this goes without complications, continue with Chapter 9 .
9. Torch Height Control (THC)
The THC works as follows. A voltage is measured between the plus and minus poles of the plasma cutter using the
cable that you install from the control box to the plasma cutter. This voltage will change as the voltage of the arc
between the plasma head and the workpiece increases or decreases. After this has been set correctly, the THC will
respond by turning the Z axis up or down. As a result, the machine will continue to follow any bent plate so that the
plasma head does not come into contact with the workpiece. All this ensures a better cutting result.
With thicker plates it is not always necessary to use the THC because it will not warp quickly. If desired, you can then
disconnect the THC control cable from the control box, so that the THC controller does not receive any values and
will therefore not respond.
For more information go to:
https://pritec-automation.com/pages/toorts-hoogte-controller
9.1 Settings
The Proma SD is set with standard factory settings. After proper connection, it can be controlled by most plasma
cutters.
When you switch on the control box, the THC display will show an “animated” “THC” message. Then a flashing
voltage value will appear for one second. The controller then undergoes an automatic calibration.
Once the controller is ready for use, three dashes will appear on the display as shown in the third image above.
