Laser Cutting

---

# Epilog

Cutting area: 81 x 50 cm

Maximum height: 31 cm

Laser power: 60 W

---

## Import

???
To import, you print to the machine interface like a printer.

---

## Camera

???
When turning on, the camera is usually offline.
You need to manually turn it on.

---
class: default-slide

## Split Colors

???
Split the imported design to different color.
This enables you to make 1 color, 1 action.

---
class: default-slide

## Size & Position & Rotation

???
Allows you to verify if it is the wanted size.

---

## Focus

???
Use plunger setting for autofocus option.

---

## Job Order

???
Choose the workflow order 
Top is First
Bottom is Last

---

## Vector VS Engrave

???
Choose what you want to do.

Cutting = Vector
Vector engraving = Vector (and not engrave)
Surface engraving = Engrave

Off = nothing happens
You can use colors to help you in designing but hidden from cutting.

Epilog detects filled objects (contrary to Lightburn)

---

## Speed & Power

???
Speed and power in %

---

## Speed & Power Precisions

CO2 Tickle Frequency [Hz]
- The frequency of the laser tickle pulse in hertz

Table Resolution [cnts/in]
- The number of encoder counts per inch of travel for the table
- Must “Home Table” if this value is changed

Power and Speed [Examples](https://www.epiloglaser.com/assets/downloads/material-settings/fusion-pro-material-settings.pdf)

???
Frequency can be seen as the distance between the dots of a dotted line.

Resolution is like your camera.

Best is to just try it out on the laser and see.

---

## Time Estimation

---

## Before Start

Switch on the extraction.
<br>
Green = On
<br>
Red = Off

---

## Switch On

Turn the key and wait until it finishes the homing process.

???
The LED around the start button (play/pause logo) will become green when the laser cutter is ready

---

## Start

---

## Onboard Interface

???
It is a touch screen.
Select the process you want to cut than click on the start button.

---

# BRM

Cutting area: 130 x 90 cm

Maximum height: 20 cm

Laser power: 150 W

---

## Importing to Lightburn

???
Or just drag and drop.

---

## Size & Position & Rotation

???
You can verify if the imported design is the same size as it is supposed to be.

---

## Job Order

[Cuts / Layers Window](https://docs.lightburnsoftware.com/2.1/Reference/CutsLayersWindow/)

???
Lightburn automatically detects color.

To change color order use the arrows.

It is limited to 30 colors.

---

## Vector VS Engrave

[Images vs. Vectors](https://docs.lightburnsoftware.com/2.1/Explainers/ImagesVsVectors/#image-uses-and-laser-behavior)

???
Choose what you want to do.

Cutting = Line
Vector engraving = Line (and not Fill)
Surface engraving = Fill

Lightburn does not detect filled objects (contrary to epilog).
You need to have a colored contour for them.

---

## Switch off unwanted color

[Cuts / Layers Window](https://docs.lightburnsoftware.com/2.1/Reference/CutsLayersWindow/#output)

???

For colors that do not need to be cut.

---

## Speed & Power

[LightBurn Explainer](https://docs.lightburnsoftware.com/2.1/Explainers/SpeedVsPower/)

???

Power Max is used when laser is at the specified Speed.

When accelerating or decelerating it uses Power Min.

You can put both of them at the same level if you do not mind more burned corners.
Otherwise you will need to find your parameters.

---

## Start From

---

## [Selecting a Start From Mode](https://docs.lightburnsoftware.com/2.1/GetStarted/CoordinatesOriginBeginner/#selecting-a-start-from-mode)

<br>

**Absolute Coordinates** tells Lightburn to output graphics in your laser's work area at a location that matches their position in your Workspace.
<br><br><br><br>
**Current Position** tells LightBurn to output graphics relative to the position of the laser head at the moment you start a job.
<br><br><br><br>
**User Origin** tells LightBurn to output graphics relative to a custom-defined origin that you set before starting a job.

---
class: default-slide

## Job origin

The Job Origin control tells LightBurn how to orient output relative to the laser head.

---

## Time Estimation

[Preview](https://docs.lightburnsoftware.com/2.1/Reference/Preview/)

???

Red is moving with laser off.

Black is moving with laser on.

---

## Switch On

]
.column[

Verify that they are turned on

1. Main Switch Key

2. Power On Button (Security Reset)

3. Laser Power Switch

4. Auxiliary Power Switch

]
]

???
If there is no laser, check if Laser Power is turned On

---

## Homing & Job Reset

---

## Moving the Head

---

## Automatic Focus

1. First, lower the bed with z↓

2. Second move the head to be on top of the material

3. Use the Focus Button

---

## Automatic Focus

---

## Frame

Always frame before cutting

???
Verify if your project fits correctly on your material.

---

## Before Start

Verify if the extraction is on.
<br>
Green = On
<br>
Red = Off

???
It is normally always on, and laser cutter will automatically start the ventilation, but better check if it is green.

---

## Start

---

# Lasersaur

Cutting area: 120 x 60 cm

Maximum height: 12 cm

Laser power: 100 W

---
class: default-slide

## LightBurn

It uses the same program as the BRM.

---
class: default-slide

## Focus

???
Manual focus.

The Red Screw driver sometimes fells off.

Always hold the lent to not damage it when unscrewing. (otherwise it fells down)

---
class: default-slide

## Before Start

Verify if the extraction is on.
<br>
Green = On
<br>
Red = Off

---
class: default-slide

## Before Start

Verify if the cooling system is on.
<br>
Green & temperature shown = On
<br>
Nothing = Off

???
It makes lots of noises when switching in.
Wait for 10sec.

---
class: default-slide

## Before Start

Verify if the compressed air is on.
<br>
(You will hear it when it is on)

???
Can be turned off while the laser cutter is idle.
