The Evo CNC Milling Machine is constructed for a permanent and regular application for professionals and hob-
byists. Due to the machine stiffness, a variety of different 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 sufficiently 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 flying 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 effect 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.
