Usage

Don't use the following materials :

MDF,
PVC plastic of other material containing chlorine,
Teflon or other materials containing fluorine,
Rubber,
Not recommended Polycarbonate (also known as Lexan, it produces a ugly edge and smokes like crazy).

If you are not sure you can use this diagram to identify the material

ALWAYS keep an eye on your job when the laser is working. Don't leave it unattended.

After each use clean the laser (lens and mirror) with a cotton swab and aceton, do not exert pressure on the lens while cleaning.

Preparation

Download Visicut, in version 1.7.9-51 or later you can download under menu 'Options --> Download recommended settings : Select "Netherlands, Enschede: TkkrLab"'
For older versions of visicut, download setting for TkkrLab
Start visicut and use menu 'Extra --> Install Inkscape Extension'

Switch on the wall & emergency button on the laser.

Put in the material

The table have to be on the right height, on the right there is a red line, the top of the material should align to this red line.

Check settings

Visicut

In Inkscape make something you want to cut. If you have your design done use men 'Extensions --> Lasercut path --> Open in Visicut'

For instructions of visicut check FabLab Berlijn

Select the right material and use the settings table for the right power/speed.

Use EXECUTE to start the laser cutter job.

Maintenance

Clean the lens and mirror after each job or at least once a day. Use cotton stick with aceton and lightly brush the surface of the mirror/lens.

Keep the rods oiled (no WD-40)

I (Duality) Quote:

Never use wd-40 as a lubricant. The primary ingredients in wd-40 are kerosene and mineral spirits, which can be corrosive and are otherwise not suitable for mechanical lubrication.

Also you don´t want a (wd-40) sprayed mirror ;).

Air Filter

Transport keep it upright (or let it rest 96 hours).

Replacement parts

Laser tube around € 500 (should last between 4000 hours (if you use always full power) - 10000 hours (if you only use engraving).
Replacement Air filter : cost € 85 for active carbon, € 200 for the rest (285 of the whole filter)). Expected life 2 years
Mirror € 80,=
