tive equipment, such as a suitable dust mask or ear protection, reduces
the risk of injuries.
CAUTION
This tool is controlled by a computer. During operation, it cannot be con-
trolled directly. Lack of caution or expertise as well as program errors can
lead to unexpected movements.
CAUTION Do not touch the motors as they can heat up signicantly during opera-
tion.
CAUTION Never place any parts of the tool or accessories in your mouth as this can
lead to serious injuries.
FOREWORD
OPERATION
The machine and all connected components have to be wired correctly and be in perfect condition.
The operator must have completely read and understood the entire documentation of the relevant machine
model and its corresponding instructions. Furthermore, he must have been trained in operating the machine as
well as its accessories and has to be familiar with the use of CNC Milling Machine and CNC software in general.
The workplace needs to be compliant with the applicable regulations and provisions of the respective industry.
The operator must use the provided dust shoe to prevent access to the cutting tool and be protected from
ejection of chips while machining.
COMMISSIONING AND SAFE OPERATION
The workpiece must be secured directly on the machine table using clamping devices.
If you want to mill through the material and produce cutouts, we recommend the use of suitable material as
spoilerboard. It is placed under the workpiece and protects the machine table from potential damage.
The workpiece should be suciently clamped in order to prevent it from unintentional shifting during process-
ing.
Never hold the workpiece with your hands during the operating process. There is a high risk of serious injury!
The entire CNC system is controlled and operated via a Raspberry Pi, using a touch screen and a custom key-
board as a user interface.
The operator must have completely read and understood the entire documentation of the CNC control software
before commissioning the CNC system.
For further questions regarding the applied control software, please contact the respective software manufac-
turer at https://planet-cnc.com/
There is no spoilerboard included in our kit. At rst, a simple MDF wood panel is enough to get a grasp on CNC
machining. When being more experienced, we suggest building a threaded insert grid on a surfaced spoiler-
board. If you intend to machine hard material and use a lubrication system on the machine, we suggest you
purchase an aluminium T-slot proles worktable, as MDF will swell in contact with water.

tions
WORK AREA SAFETY
NOTICE Keep work area clean and well lit. Cluttered or dark areas are prone to ac-
cidents.
NOTICE Operate the machine only in interior spaces on a solid, horizontal table or
workbench.
CAUTION Keep children and bystanders at a distance while operating a power tool.
Distractions can cause you to lose control and can result in accidents.
CAUTION
Do not operate the machine in explosive atmospheres, such as in the
presence of ammable liquids, gases or dust. Machines can create sparks
which may ignite the dust or fumes.
USE OF THE MACHINE
NOTICE Do not leave a running tool unattended, turn power o. Only when tool
comes to a complete stop and is disconnected from the mains it is safe.
NOTICE
Use the machine and accessories in accordance with these instructions,
taking into account the working conditions and the work to be performed.
Use of the machine for operations dierent from those intended could re-
sult in a hazardous situation with high probability of supercial injury.
NOTICE
Never use dull or damaged end mills. Sharp end mills must be handled
with care. Damaged end mills can snap during use. Dull end mills require
more force to cut the tool, possibly causing the end mill to break.
NOTICE
The speed and feed of the end mill when carving, routing or cutting is very
important. Always observe the speed and feed for the particular end mill
recommended.
NOTICE
Do not allow familiarity gained from frequent use of your rotary tool to be-
come commonplace. Always remember that a careless fraction of a second
is sucient to inict severe injury.

PROTECTIVE MEASURES
ADDITIONNAL SAFETY MEASURES
CAUTION
Depending on the application eld of the machine (private or commer-
cial), observe the applicable occupational safety and health, safety and
accident prevention and environmental regulations.
WARNING
Some dust created while machining certain types of material can
contain chemicals known to cause cancer, birth defects or other re-
productive harm. Always inform yourself on the material you have
at hand before machining it. Some examples of these chemicals are:
lead from nonferrous metals with lead content, carbonate from car-
bon ber, arsenic and chromium from chemically-treated lumber.
Your risk from exposures to these varies, depending on how often you per-
form this type of work. To reduce your exposure to these chemicals: work
in a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to lter out microscopic
particles.
The Evo CNC Machine has been designed for advanced users and is only to be operated by technically skilled
persons above the age of 18.
The machine is only to be used in a technically perfect condition, which is to be ensured by the user prior to
each operation.
The emergency switch as well as, if applicable, additional safety devices, always need to be easily accessible and
fully functional.
The use of lubrication systems is allowed. Please take into consideration that if you are using a MDF spoilerboard
(machine worktable), the MDF panel will swell and be damaged by the water.
ASSEMBLY & SYSTEM SETUP
The machine is solely suitable for the operation in dry, interior spaces.
Keep the environmental temperature of the machine dust-free. High dust exposure can cause damages to the
system.
The humidity should be within normal limits for humidity indoors (40 to 60 %). Protect the machine against
wetness and humidity.
The ideal environmental temperature for the system lies between 18°C to 25°C, respectively from 64°F to 77°F.
Particularly protect the electronics against overheating by avoiding direct sun radiation or indirect heating up
nearby a radiator.
Place the machine on a suitable table or on a machine stand. In order to provide a comfortable working height,
we recommend a working height of approx. 840 mm. For a torsion-free stand, the surface of the machine stand
needs to be solid and even. The machine is to be secured in a way that it cannot shift or fall down.
All movable parts of the machine must be able to operate collision-free.
The routing of the tool´s cables, such as with the milling motor, has to be eected in a way that the cable cannot
be clamped between the guide ways of the machine. For this purpose, use the cable chains we have set up for
the dierent axis.
The machine has to be easily accessible and operable. Especially the emergency switch has to be easily acces-
sible at all times.
Take care to ensure a sucient illumination of the machine`s location and the workplace surrounding the ma-
chine.
The control unit has to be ideally placed under the work area of the machine and the interface unit has to be
placed in the vicinity of the machine.
Please follow carefully our attached mounting guide and datasheet in order to properly mount your Mekanika
CNC machine.
If you have any questions, please do not hesitate to contact us!
ENVIRONMENTAL CONDITIONS
MACHINE POSITIONING
MACHINE ASSEMBLY

12 9
The Evo CNC Milling Machine is constructed for a permanent and regular application for professionals and hob-
byists. Due to the machine stiness, a variety of dierent materials, such as wood and non-ferrous metals, can
be processed.
The plausible and reasonable scope of uses include:
• Manual movement mode, using a digital“jog”to move the machine along its 3 axes independently.
• Automatic Homing procedure, operated by the user by clicking on a button. This procedure moves the ma-
chine sequentially on each of its axes in the following order: Z, X, Y, until it encounters the limit switches.
• Automatic Square Gantry procedure, operated by the user by clicking on a button. This procedure moves the
machine along its Y axis towards the front until it reaches its limit switches on both sides of the axis.
• Measure Tool Length procedure, activated by the user by clicking on a numerical button. This procedure
makes the machine descend at reduced speed along its Z axis until its tool comes into contact with a remov-
able sensor previously placed by the user.
• Normal operating mode, where the machine moves automatically according to a machine code, called
G-code, previously loaded by the user.
• Manual control mode using a terminal, the machine moves according to a machine code, called G-code,
entered directly by the user.
The plausible and reasonable scope of interventions include:
• Manual movement of the machine to access certain zones.
• Adjustment of the belts tightening.
• Adjustment of the wheels tightening;
• Changing the cutting tool on the milling spindle.
• Attachment/removal of the dust shoe.
• Attachment/removal of the raw material to be machined on the work surface.
• Switching on, pausing and stopping a machine code (G-code).
• Connection/disconnection of external machine cables.
• Opening of the cable entry chains to access the cables.
The workplace needs to provide enough space around the CNC Milling Machine in order for the machine to
work comfortably and to be able to fully use its traveling paths. Additionally, a safe distance to possibly nearby
positioned machines is to be maintained.
The location of the machine as well as the workplace surrounding the machine has to be suciently illuminated.
WORKPLACE
INTENDED USE OF THE MACHINE
PERSONAL PROTECTIVE EQUIPMENT
EMERGENCY STOP BUTTON
When working with the Mekanika CNC Machine, the operator has to wear at least the following personal protec-
tive equipment and has to be compliant with the below-mentioned safety aspects:
• Safety glasses to protect the eyes against ying chips and other projections.
• Ear protection to protect the ears against noise.
• Safety shoes to protect the feet against falling objects.
• No wearing of clothes which can get caught in the machine, such as ties, scarves, wide sleeves. Roll up
sleeves to prevent caught in moving parts. Additionally, jewellery, watches, rings and especially long neck-
laces and rings are to be dispensed with.
• Shoulder-length or longer hair must be secured with a hairnet or a hat in order to prevent it from getting
caught in the linear guides and / or rotating tools.
Prior to all adjustments to the machine, such as to the milling motor and to the control box, its control or sys-
tem-guided tools have to be disconnected from the power source.
Never hold the workpiece with your hands. It is mandatory to secure the workpiece on the worktable. Otherwise,
there exists a high risk of injuries!
The emergency stop is located in a separate housing with a magnetic disk and is securely connected with the
machine. In order to be able to intervene at all times, the emergency stop has to be positioned at a suitable
place.
By pressing the emergency stop switch, the emergency stop is triggered. The control of the machine is immedi-
ately interrupted. Additionally, the control software receives the signal to stop the operating process, freezing
the user interface. The machine stops moving immediately.
ATTENTION! The emergency stop switch can only eect the stop of all components if these components are
electronically connected with the emergency stop switch. The spindle motor, that features a separate ON /
OFF switch, is NOT controlled via the Raspberry Pi and the USB controller. The milling tool will continue to run
although you have activated the emergency stop switch, leading to a risk of personal injury and damage to
property if you don’t act with caution.
If you want to deactivate the emergency stop status, reactivate the control by turning the emergency stop
switch to the right. The operating process has to be restarted.
If you have any questions on this matter, please do not hesitate to contact us.
RESIDUAL RISK
Despite all safety precautions against the contact with rotating or hot tools and the protection from crushes, a
residual risk remains due to a careless handling and automatic movements of the CNC system.

CHECKLIST FOR A SAFE USE OF THE MACHINE
SAFETY SYMBOLS
MACHINE DESCRIPTION
The Evo CNC Milling Machine is a digitally controlled milling machine, which can be used for a regular process-
ing of wood, plastics and non-ferrous metals.
The machine has three axes which are oset by 90°. This way, it is possible to travel to any point within the
working space. Each axis is equipped with one or two stepper motors and with one mechanical micro-switch,
working as a limit sensor. The stepper motors drive the movable axes elements via a belt and pulley system The
position of the axis is determined during the homing procedure, at the beginning of the job, with the aid of the
limit sensors.
The Evo CNC machine is delivered as a kit and includes the following components:
• A 3-axis CNC router, with 4 motors and 4 limit switches
• A plug-and-play electronic control unit, already assembled and tested
• A plug-and-play interface unit, composed of a touch screen and keyboard
• PlanetCNC software, pre-installed on a Raspberry Pi 4 and already congured (software used to control your
machine)
• A lifetime license of PlanetCNC
• A power cable for the control unit (EU plug)
• An AMB (Kress) 1050 FME-1 milling motor
• A touch probe device to locate your workpieces easily
• All the basic tools necessary to assemble the machine
• A USB key with all the necessary documentation
In addition to the above mentioned items, you will need the following ones in order to be able to properly use
the machine:
• A spoilerboard. At rst, a simple wood panel is enough to get a grasp on CNC machining and we don’t think
it’s relevant to ship such an bulky object, which is easy to nd at your local hardware shop. When being
more experienced, we suggest building a threaded insert grid on a surfaced spoilerboard. The procedure to
build one is described on our website under the Learn section.
• A vacuum cleaner and a dust shoe, to help you work in a clean environment and to be protected from the
rotating tool while the machine is working.
• A CAM software. You will need a Computer Aided Manufacturing software to translate your 3D models into
a G-code readable by the machine. We suggest to use Fusion360.
• A table which can bear the weight of the machine.It needs to be robust and sti, as vibrations will aect
the precision of your cuts.
