1.0 Safety.
Caution: Plasma cutters are a source of life-threatening voltage (in
HF/HV models it can exceed 10,000V) and generate very high interference
which can disturb or damage the electronics (computer, controller,
controllers). Assembly and connection should be carried out by a
person with electrical qualifications.
Failure to make good contact between the material/ground clamp
terminal and the material to be cut can lead to irreparable damage to
electronic equipment.
1.1 rounding, shielding
Protective earthing is used to discharge the dangerous potential of
the plasma arc to earth. The resistance to earth of the structure should
not exceed ΩIt is important not to make a ground loop. The
disturbance/overvoltage should have only one way of escaping to earth and
it is unacceptable for it to have an output to earth through electronic
components. This can be implemented by electrically separating the
control part from the machine structure and connecting it to earth via a
separate conductor ( usually the PE protective earth of the mains supply -
via the electronics supply cable ).
When connecting the protective earthing of the control box to the
machine structure ( i.e. using the same earthing as the structure ), do not
use any other earthing source that could create a ground loop.
In order to minimise the influence of interference, the plasma source
as well as the torch cable should be placed as far as possible from the
control cables and the computer. The use of shielded cables, the shields of
which are connected to the earth bar only on the control box side, will
considerably reduce the influence of interference on the operation of the
machine (see example diagram 2.0).

1.2 Emergency stop
The controller has a emergency stop push=buton input labeled
as E-STOP, which interrupts the controller's operation, disables all
optional outputs as well as blocks the possibility of restarting until the
emergency button is unlocked. At all times - especially when
commissioning the system - be prepared to press it quickly in case of any
problems.
NOTE : The controller input interrupts the operation of the
controller. For full protection, the auxiliary contacts must be used to
disconnect the power supply to the machine, which is not part of this
manual and should be carried out by the installer. This description refers to
stopping the operation of the MyPlasm CNC system.
The E-STOP button should short-circuit the IN input ( middle
terminal ) to the MINUS ( right terminal ) of the controller's E-STOP
input. In the programme configuration it is possible to select the type of
NC / NO contacts (described later).

3.0 Basic parameters and requirements
The MyPlasm CNC control system is
managed via USB 2.0 via the Windows control
software, which can be downloaded for free from
the manufacturer's website:
proma-elektronika.com → "download".
The software has a freeware licence which does
not exclude use for commercial purposes.
The control software works correctly on
Windows XP, 7, 8, 10, 11. The additional
modules MyMiniCAD and 3D Viewer require at
leastWindows 7. The software has very low
requirements and works with any PC / Laptop
hardware configuration.
Power supply for the controller: 24V DC ( 22 - 26V DC)
Maximum current consumption : 0.6A ( 600mA )
Number of axes : 4
Motor driver output signals : TTL 5V STEP (PUL) / DIR 40mA
Motor frequency: 0.02 - 250kHz
Limit sensor inputs ( 8 x 4V ) : NPN NO, NPN NC, Contacts,
active state : LOW
Dimensions of CNC Controller : 120 x 100 x 15 [mm].
Dimensions of the Plasma Interface: 115 x 60 x 25 [mm].
Measuring voltage ARC / THC max : 300V DC ( test 1000V DC )
HF / HV protection : 10kV AC ( 15kV AC test )
Optical isolation : 2 x 3kV
PC communication : USB
Plasma Interface Communication : RS485
Optional outputs ( ) : OC 0.5A 5-30V

4.0 Commissioning the controller
Initial commissioning should be carried out STEP by STEP as
outlined in this manual. If something does not work correctly in one step
then there is no point in moving on to the next step without finding and
solving the problem. If user connects and configures everything at once, it
can be very difficult to find a possible error.
4.1 Software installation
DO NOT CONNECT THE CONTROLLER TO THE COMPUTER
BEFORE INSTALLING THE SOFTWARE AND USB DRIVERS !!!
The latest software version can be downloaded from the
manufacturer's official website: proma-elektronika.com → tab
"download". When installing the software, the USB drivers are
automatically installed. At the time of writing this manual, this is version
1.2.0 and the description applies to this version. During the first start-up,
select the language and units used in the programme.
The instructions assume that the software has factory settings. If this
is not the case, it is recommended to restore them during the first start-up.

4.2 Power supply and initial start-up
IMPORTANT !!! Use the original USB cable supplied with the system
by the manufacturer !!! Do not use USB extensions.
The controller requires a 4V DC power supply to operate ( 1 - A
recommended ), the controller's current consumption does not exceed 0.6A
( 600mA ). If the power supply is more powerful ( more than 1.5A ), an
external 1A delay fuse should be used.
First connect only the power supply and the USB cable.
The top right corner of the screen displays the status of the connection to
the controller as below examples..
Communication OK - Communication correct, controller firmware
version compatible with the software installed on the computer.
No USB device : Device not connected to USB port or problem of driver
installation in Windows.
Communication error : Device installed and connected correctly but
communication error occurred. Problems with the 24V DC power supply
to the controller or incompatibility of the Firmware version with the
software version installed on the computer. If this is detected, the software
will attempt to automatically upload the correct Firmware version.
In the event of problems, it is possible to manually force a
Firmware update by holding down the SHIFT key and resetting the
communication.
8
If everything is working correctly the program should display a
message about correct communication with the controller. There may be
a message about a communication problem RS485 / with the plasma
interface ( because it is not currently connected ).
The message should disappear when the Plasma Interface is deactivated.
In this state, the software should not display errors. It is possible to
control the controller outputs. By clicking the manual control arrows ( or
keyboard arrows ) the XY axis coordinates should change and the blue
LEDs on the STEP(PUL)/DIR outputs of the controller should light. The
PgUp / PgDown and Green arrow keys are used to control the Z axis. The
PUL LEDs light up always during movement and DIR only in one
direction ( determines the direction ).
9
4.3 Connecting the motors
The controller generates STEP(PUL) / DIR signals TTL ( 5V ). It
can work with stepper motor drivers, servo stepper motors and servo
drives if they support 5V STEP (PUL) / DIR signals .
The controller outputs have been designed to drive the opto-isolated inputs
of the controllers. In order to minimise the influence of interference,
connections should be made with twisted pairs of wires (max 50cm ).
If the machine is equipped with a second motor on one axis, it can be
connected to the auxiliary output PUL' / DIR' and configured accordingly
in the program in the electronics tab :
