Inhoudsopgave

Auto Focus vs Manual Focus

In order to engrave or cut a crisp, clean image, your material must be the correct distance from the bottom of the focus lens. Setting the distance from the bottom of the focus lens to the top of your material is the process of focusing, and is accomplished by placing your material on the table and moving the table up or down.

Auto Focus

Activating the Auto Focus can be done on your computer in the Auto Focus box in the Dashboard. The default setting is “Off”, however you may also choose between Thickness mode or Plunger mode.

Thickness Mode: If you select this mode, you must enter the thickness of your object in the Processes Section under each individual process. If all processes in your job need to be focused at the same level, it may save you time to enter the thickness before splitting the job into multiple processes.

For more information on thickness mode, or the auto focus plunger, visit our training site: support.epiloglaser.com

Manual Focus

These photos show the Manual Focus Gauge that is used to determine the correct distance from the focus lens to the top of your material. This gauge is included with your system.

Place the object to be cut or engraved anywhere on the table of the machine. Select the Jog button on the touch screen and use the Joystick to bring the focus gauge to the object. Deselect the Jog button, then select the Focus button on the touch screen and move the Joystick up or down to move the table appropriately until your material just touches the bottom of the gauge. The speed at which the table rises or lowers can be controlled by applying varying pressure upwards or downwards on the Joystick.

You may also fine-tune the table height in the Focus Menu. Once the focus position has been established, you can remove the gauge. Press the Focus button to leave the menu and then press the Reset key to bring the laser head back to its Home Position.

Helpful Note:

If your material has a taper or curve, pick an intermediate point between the highest and lowest points being engraved and focus on that point. In general, the area of the material being engraved needs to be relatively flat. If the area being engraved differs in height by more than about 0.125” (3 mm), the image will begin to look “fuzzy” or out of focus.

Let op:

Do not leave the Manual Focus Gauge in place when running jobs or when using Auto Focus!

Let op:

If you are using Auto Focus or the Manual Focus Gauge and you know there is not enough clearance between the lens carriage and your material, you will need to lower the table before you insert your material and start the job. To lower the table, use the Joystick while in the Focus menu to lower the table enough to accommodate your part.
