Warm-up is a necessary process for your machine to mill as intended.
Ideally, when you start your machine, the machine prompts you to warm up. 

If the machine is idle for about 2-3 hours, you need to do the warm-up again manually before starting milling.

After opening the warm-up file, click start to run the warm-up.

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.

You can do the tool replacement either for changing, broken/worn-out tools or first time installing the tools. 

Press the "Replace tool" button on the Jog Control page of the program.
The tool table will come up on the opened page.

The Last tool is measuring spindle length.

● Click the number on the “No" column to select the tool number you want to identify or change.

● Select the type of tool you want to define or change from the "Type" section on the upper right.

● Click the “Replace Tool" button. 

On the screen, you will receive a message box that is prompting you, it will place the tool inside the spindle to its dedicated location.

You will receive a second message box that is asking if you could change the tool in this spindle position, or do you want to send the spindle to the home position for easier tool replacement.

When the "Replace Tool" operation is completed, you will see that the tool number information on the lower left side also changes.

Before clicking the collet button, make sure to hold the tool with your hands, to prevent the tool from falling. (This only applies to tool change)

When you receive the third message, you can now replace the tools by clicking the collet button. If this is your first-time tool installation, the spindle will be empty and again clicking the collet button you can place your tool inside the spindle.

In the new message that appears on the screen, click on the "OK" button, asking if you want to measure the length of the new tool.

Finally, after measuring the tool length, a message will appear on the screen informing you that the tool change process is finished. Click the "OK" button. Finish the tool change and installation process. 

Start milling

Click file at the top left side of the window and open batch jobs.

Double-click on the shown box, then select the file you want to process.

“Warm-up” is an example.

The “work in” section should always be “left”

If you have one file, you. can click on “check file

If you have multiple files you can click on “check all

You can start to mill after clicking on “ start the job”

Stop milling

Press the "stop" button to stop axes movements.

Press the "CW" button to stop the spindle.

Press the "home" button to send axes to the home position.

Resume milling after interruption

The program will be called after you pressed the "yes" button.

Press the "start" button.

The program will resume where it left off when you press the "OK" button.

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 month 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.

Rotate and unlock the security of front panel socket and disconnect it.

Disconnect up and down air hoses for front cover.

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.

If your machine hasn't been running for more than 15 minutes before starting the calibration, be sure to run the machine warm-up program before starting the calibration.

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)
