Power cable

These are the optional products.

Placing the disc

Screw tightness should be just enough to hold the blocks so your block won't rotate while milling. If you overtighten you might damage your soft material blocks.

Place the desired block you will mill into the block holder.

Tighten the screws with provided allen key until the block is secured and won't move. 

Tool replacement

When changing a new tool or when you remove tool from the spindle, the tool length must be measured.

Press the “Tools tab" button on the main tab of the  CNC program. The tool table will come up on the opened page. Then click on the pocket number to either install a new tool ( If the pocket station is empty) or to change the tool.

For tool installation;

To install the tool, navigate to the page of the desired tool and proceed by pressing the "Mount/Release" button.


When the movement stops, click on the “collet open” button and insert the new tool inside the collet. Then click on the “collet close" button while holding the tool.

Kill the old tool life, then adjust the maximum write tool life according to the tool type.

Click on the "Measure" to measure the tool length.

Then click on the "Restore button" to finish tool installment.

For tool change;

To change the tool, navigate to the page of the desired tool and proceed by pressing the "Mount/Release" button.


Once the tool is on the spindle, hold the tool with one hand then press the "collet open" button. 

Remove the old tool then insert the new tool. Then press the "collet close" button.

Click on the “Measure” button to measure the tool length.

Click on the "Restore" button to finish tool replacement.

Start milling

The jobs needs to be placed in “NC” folder, pinned on windows taskbar. (Directory of the “NC” folder is “D:\isac\lav\lav”.)

Double-click on the name bar.

Select the file you want to process and click on "Apply" button.

Press “start” button to begin milling.

Stop milling

Press the "pause" button to stop axes movements.

Press the "start" button to resume milling.

Press to stop milling. (Resets the CNC program.)

Resume milling after interruption

In the event of an interruption such as a power outage or similar interruptions, the program can be resumed from the last successful tool checkpoint.

General cleaning

Do not blow compressed air into the machine.

Daily cleaning

There are bellows in your milling machine to protect rails and guides. These rails and guides are essential for precise axis movements. Make sure to clean the Y axis bellows the upper section and lower side sections daily, so the dust and particles won't clog and prevent the axis movement.

You need to clean the bellow link threads with help of a brush.

Cleaning back bellows of Y axis can be hard since B axis metal sheet blocking your way. Push the particles to the sides with help of a brush.

Lastly you need to clean the side edges of your bellows.

Collet cleaning

The spindle is both the most powerful and the most sensitive part of your machine. Even a slight vibration can cause imperfections.
Make sure to clean the spindle collet once a week with the collet cleaning kit you receive with the machine.

Open your collet and hold the tool with your hand if there is a tool inside the spindle. Remove the tool and leave the collet open.

Use the collet apparatus to loosen the collet. Then remove the collet by rotating it.

Put a little solution on to small brush and clean the insides of the collet.

Use big brush to clean all excess debris may have been inside the collet.

Use conical cleaning part to clean inside the spindle. 

Screw your collet inside the spindle by rotating completely inside the spindle. Use the collet apparatus to gently tighten the collet. Make sure your collet is semi-tightly screwed into its place.

Drains cleaning

For better cutting liquid circulation, drains inside the machines should be checked and cleaned once a month.

Zirconia dust, or metal shavings can collect inside the 90 °C fitting and may prevent drainage.

Fitting can be cleaned by clearing blockage with a stick-like object.

Tool measurement sensor probe cleaning

The dust and particles beneath the measurement probe can pile up and prevent the movement of the probe. This may produce miscalculations, can cause tool breaking, or even worse machine malfunction. 

The probe must be checked weekly. 

You can clean underneath of the probe with a brush. After cleaning check with if the probe is free to move.

Brush might not be enough with wet milling. Zirconia and cutting liquid can be hardened. If that is the case please use a penetrant/lubricant sprey such as Wd40.

Deep cleaning

Make sure to turn the machine and air off before starting.

Deep cleaning requires you to remove the machine cover to clean hard-to-reach areas of your machine easily.

After you have removed the front cover clean your machine throughly with an electric vacuum cleaner. Zirconia dust may cause malfunction for regular vacuums, we suggest an industrial vacuum.

Remove the top cover

Disconnect the grounding cable.

Disconnect the tablet computer cables and remove the tablet pc.

Remove the cable cover by unscrewing it.

Disconnect the cable from the socket.

Locate the air hoses behind the back panel.

You can disconnect the air hoses by simply pushing the circle around it inside.

You may remove the cover by lifting up first and then pulling towards out.

General maintenance

The need for maintenance is based on actual or imminent failure. Ideally, maintenance is carried out to keep equipment and systems running efficiently during at least their usual life cycle.

Make sure to have your machine in tip-top shape to keep the precision high.

Collet tightness checking

You should check your collet tightness once a month.

Also when the margins are thinner than expected, collet tightness is the first to examine. 

Checking air pressure and humidity

You can check both the air pressure from the gauge and humidity on the plastic tube on the conditioner which is located at the back.

You can check the air pressure from the gauge

You can check the humidity from the tube: You can tell from condensed water drops or water that has accumulated inside.

Calibration and measurement

Calibration is the act of comparing a device under test of an unknown value with a reference standard of a known value. A person typically performs a calibration to determine the error or verify the accuracy of the device under the test’s unknown value.

Make sure that the calibration tool is present on your machine. If you do not have a calibration tool in the spindle or in your pick-up station, first install the calibration tool on your machine.

Connect the calibration disc sent with the machine to the disc holder of your machine. (10 to 14 mm wax discs)


Calibration without RTCP will only be needed after a mechanical adjustment has been made. ( This calibration is done only with the supervision of technical support.)

Calibration RTCP

Under normal circumstances, calibration RTCP should be done during seasonal changes. The machine should be calibrated in thermal equilibrium and near constant ambient temperature. That’s the reason why we are calibrating Yenadent machines in seasonal changes as the ambient temperature changes accordingly. Only calibration program 1 and calibration program 2 are needed for the user.

Calibration program 1

Make sure the dotted place on the block is not milled. The part will be milled here.

Press the “Calibration program 1" button. The machine will start the calibration program.

Calibration program correctly finished. Return to the selection menu.” A message will pop-up. Click on the “Back to the selection menu button”. Then proceed to “Insert measurements

Do the measurement as shown below. Then enter the values into the corresponding boxes in the program 1 section.

If (***) threshold error occurs, contact technical support.

Calibration program 2

Make sure the dotted place on the block is not milled. The part will be milled here.

Press the “Calibration program 1" button. The machine will start the calibration program.

Calibration program correctly finished. Return to the selection menu.” A message will pop-up. Click on the “Back to the selection menu button”. Then proceed to “Insert measurements

Do the measurement as shown below. Then enter the values into the corresponding boxes in the program 2 section.

If (***) threshold error occurs, contact technical support.
