Maintainers

The @lasertechs are responsible for general maintenance, repairs etc.
Users need to perform some maintenance tasks at the beginning and end of their session (covered in the Induction)

If you would like to become a laser inductor, please contact the @lasertechs .

Induction

You must not use the laser cutter without being inducted first. Improper use can cause serious damage to the machine. The laser has a Tool Control system that will only turn the laser on for inducted users.

To get inducted:

Inductors: Here is a suggested induction presentation (status: mature - been used for several inductions).

Unlisted

If your material is not explicitly permitted or forbidden, then do the following, in order of operation:

  1. Look at the datasheet for the product and see if it is specifically listed as “laser safe”.
  2. Look at the Trotec youtube channels (USA, Canada) and see if they cover the user of the material.
  3. Look at the official Trotec materials shop or download their catalogue for an equivalent material.
  4. Please start a thread in #discussion:private to get everyone’s opinion before attempting a cut
  5. If you are still unclear, ask the @lasertechs for “permission” to experiment

Obtaining Materials

Our Shop

  • Sheets of ply and acrylic in various thicknesses are available in the shelves below the Laser PC.
  • Purchase online via the online shop at southlondonmakerspace.org/shop or via the QR code on display at the laser station
  • Sheets are approximately 405 x600mm

Free materials in the space

  • Cardboard is available in the store shelves for test cuts, jigs and cool cardboard projects
  • The scrap pieces in the clear boxes under the mini-CNC are free to use.

Alternatives

Your Scrap

Please contribute usable scrap pieces left over from your sheets

Important Maintenance Checks

It is important the the following checks are done before and after each Laser Session

Check the Nozzle

Unscrew the nozzle and clean any residue

Check the Lens

Check the lens for any dust or scratches, and clean if needed

Check the Mirror

Laser Control Software

Ruby

The laser runs on software called Ruby

Resetting Your Ruby Password

On the Laser PC:

  1. Go to Desktop / Reset Ruby Password
  2. Enter your email
  3. It will confirm you’re found and your temporary password has been set (or say not found).
  4. Users will have to set their own password upon login. The temp password (printed when you launch the script) is Aaaaaaa1

JobControl - the original software - is being phased out by Trotec and may become unsupported at short notice, please make sure you are inducted on Ruby - more details on how to use Jobcontrol can be found here

Material Settings

You need to set the power and speed in order to achieve the engrave or cut that you want. The settings are determined by the type of material and the sheet thickness.
Please refer to the Ruby manual to see how to set these, we also have recommended settings for common materials listed here.

Giving Back

  • In return for the loan of the laser cutter, we have promised to promote interesting projects. Please consider writing up your project for our blog, or tagging @trotecuk and @ldn_makerspace on twitter.
  • You can also volunteer to become a lasertech and help with maintenance, or run inductions and training sessions

Getting Help

  • Contact @lasertechs on Discourse if you are having any problems with the machine.
  • Trotec Operation Manual (generic, doesn’t include information about our specific laser and how we use it, but does fulfil the function of a datasheet).
