1.2 Mini XLR Jack
The miniXLR jack provides the option of connecting extensions without additional hardware.
For example:
Tool length control, Security housings with door switch
3D Buttons
Note:
Concomitant use of this socket and a 4th axis, such as a rotation axis or tangential knife, the
connectivity is limited because both the miniXLR socket and the reference switch the 4th axis are
found via the PIN15 of the LPT port.
For this combination, we have a solution. To do so, please contact our customer service.

This guarantees also that the power supply is interrupted at faults and in emergency case.
The maximum power consumption per outlet may not exceed 8A.
The current consumption of the two sockets together may not exceed 13.5A.

5.2 Milling motors
Milling motors by Kress:
Art. 211105 Kress 1050FME-1 / 1050 W / 5.000 - 25.000 R/min
Art. 211110 Kress 1050FME / 1050 W / 10.000 - 29.000 R/min
Art. 211100 Kress 800FME / 800W / 10.000 - 29.000 R/min - 110Volt (for USA)
Our recommended milling motors Kress; can be attached directly to the Z-axis in the designated
tool holder (Ø43mm).
The milling motor itself contains an on and off switch and setting wheel for the speed. A speed
control via software is not possible here.
However, the milling motor can be turned on/off via the relay socket 1 (Rel.1) Zero-3 control via
software or program.
- Make sure that the control is turned off.
- Connect the power cord to the socket 1 (Rel.1) Zero-3 controller.
Of course, milling motors by other manufacturers can be connected in this way.
You should also read the notes from chapter 2.2 for max. current consumption.
5.3 Noga spray cooling with solenoid valve
Art. 350100 Noga spray cooling - without solenoid valve for manual operation
Art. 350110 Noga spray cooling - automatic control via solenoid valve
Art. 310250 Vacuum pump / compressor -0.7 bar / 2.5-3.0 bar
The Noga spray cooling requires an air pressure of min. 2.5 bar. from a compressor. This should be
designed for continuous operation. For this application we have a small, handy pump in the
program (see above).
Via solenoid valve, the air supply from the compressor can be automated by software or program.
This is recommended by us. This has the advantage that lubrication is only done when it is
necessary.
-Make sure that the control is turned off.
-Connect the power adapter to the socket 2 (Rel.2) Zero-3 controller.

5.4 Inverter and HF spindles
The output from the software WinPCNC PWM signal for the spindle speed is converted by the
zero-3 into an analogue control signal and outputted to the 0-10Volt LPT2 output.
Thus you can connect an inverter to operate a HF spindle directly to the Zero-3 controller.
-Make sure that the control is turned off.
-Connect the power cable of the inverter to the power outlet 1 (Rel.1) Zero-3 controller.
-Connect the "control cable" of the inverter with the LPT2 output of the controller.
-Make sure that you back up all connections with the knurled screws from loosening.
-Observe the notes from page 6 for max. Power consumption.
Caution:
Inverter and HF spindles that have higher performance, can also be used, but require an external
power supply!
Please feel free to contact our Customer Service.
5.5 Granitograv and laser engraving unit
Art. 230100 Granitograv CNC-Module
Art. 220500 Laser engraving unit
With this accessory, there is an additional control box that needs to be powered. For this purpose,
each power supply can be connected to the Zero-3 controller. As a result, the accessory is
disconnected from the power in emergency case!
-Make sure that the control is turned off.
-Connect the power supply of the respective control box with the socket 1 (Rel.1) of the
Zero-3 controller.
Please note for operation the associated manuals with more detailed information!

6.1 WinPCNC
WinPCNC is a convenient and comprehensive 3/4-axis NC control under Windows for milling,
drilling, engraving, dosing, and more.
Different variants with graded functions and prices provide the right solution for beginners and
model makers, as well as semi-professional use or for demanding industrial plants.

The additional hardware ncUSB (WinPCNC USB) and the USB dongle (WinPCNC
Economy) should be connected only after installing the software to the PC. The
required drivers are installed and the hardware can be detected correctly afterwards.
6.1.1 Installation
Now, let us start the initial installation of the software WinPCNC .
Install the software from the supplied CD into the directory specified for it. After installation, you
may have to restart the PC.
.
6.1.2 Connecting the computer to the Zero-3 control
The connection of the computer to the Zero-3 controller depends on the software and the associated
additional hardware. (see page 12)
-Make sure that the control is turned off.
-Depending on the software, connect the supplied connection cable to the PC and the
controller. Secure all cables against loosening!
-For WinPCNC variants Light and Economy there is no additional hardware interface, the
LPT cable is connected directly to the controller.
-In the other variants of the PC is connected to the additional hardware interface. This is then
connected via LPT cable to the controller.
-In all variants, the LPT2 port is only used for optional accessories, and some machines
extensions.
The additional hardware (ncUSB, USB dongle) is now recognized and installed by Windows.

6.1.3 Configuration
Start the software WinPCNC.
From the Start menu choose language and machine type.
The specification of the correct type of machine is very important because the software
automatically loads all important parameters for the selected type of machine.
The communication between PC and Zero-3 is controlled depending on the software version on the
LPT, USB or serial interface.
In WinPCNC USB installation and configuration is complete. In this version WinPCNC determines
the interface automatically.
With other versions yet the interface or port address of the PC must be determined on which the
communication runs.
6.1.4 Determination of the LPT interface (Light and Economy)
With the variants "Light" and "Economy" the LPT port or the port address must be entered in
WinPCNC (see page 17).
Some computers have multiple LPT ports, so that the right one first has to be found out. If the
interfaces are not marked on the PC, you need to find out which interface you have connected to the
control.

How do you find out the correct port address of the LPT port?
In the Device Manager of the PC all available interfaces are listed.
Standard interfaces, see Ports
(COM & LPT)
Use interfaces on expansion
cards (interface cards), it may be
that this is a multifunction
adapter or similar in the Device
Manager!
Select the interface to which you have connected to the machine. Go to the properties of the
interface (eg with double-click) and look under Resources after the port address (I / O area).
This is the first entry (4-digit hexadecimal) as seen in the screenshots.
When using 2 LPT ports (only Economy) please repeat with both connected interfaces !
This port address (es) you must now enter in WinPCNC (see 6.1.6).

6.1.5 Determination of the COM interface (Professional)
For all "professional" versions the COM interface must be entered in WinPCNC (s. Page 17).
Some computers have multiple COM interfaces so that the right one first has to be found out. If the
interfaces are not marked on the PC, you need to find out which interface you have connected to the
control.
If the PC has no COM port, it is possible to work with a USB / Serial converter . This adapter then
emulates a COM interface. (see below COM4)
Art. 400305 Digitus DA-70156-VPR2.0 USB to Serial Converter
In the Device Manager of the PC all available interfaces are listed.
Standard interfaces, see Connections
(COM & LPT)
Here you can see, for example, a PC with three COM ports
(COM1, COM2, COM4).
The machine is connected in this case to COM4.
In WinPCNC you must then select COM4 (see 6.1.6).
The COM4 interface is provided via the USB / Serial
converter. This is indicated by the entry USB Serial Port
(COM4).
