- This machine should not be operated without induction.
- This machine should not be left unattended during operation.
This is a Trotec Speedy 300. It is a professional-grade laser cutter and is a very high-quality machine. It is used for cutting and engraving many materials including plywood, acrylic (perspex), card, leather, some plastics and many others.
Cutting area : 726 x 432 mm
Maximum cut depth: 12 mm
Maximum work piece height: 200 mm
Maintainers and Inductors
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)
Current inductors are:
If you would like to become a laser inductor, please contact the @lasertechs .
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:

Add yourself to the waiting list for the practical induction
Inductors: Here is a suggested induction presentation (status: mature - been used for several inductions).
Laser Induction v9.pdf (2.0 MB) - 10/03/2023
- laser grade plywood
- perspex / acrylic
- glass (engraving)
- laser grade rubber
- non-treated woods (max thickness depending on type of wood)
- anodised metals ONLY FOR ENGRAVING (contact @ lasertechs if you want to etch metals)
- Polyurethane foams
- All non-laser-rated wood
- Circuit boards
- cutting all metals
If your material is not explicitly permitted or forbidden, then do the following, in order of operation:
- Look at the datasheet for the product and see if it is specifically listed as “laser safe”.
- Look at the Trotec youtube channels (USA, Canada) and see if they cover the user of the material.
- Look at the official Trotec materials shop or download their catalogue for an equivalent material.
- Please start a thread in #discussion:private to get everyone’s opinion before attempting a cut
- If you are still unclear, ask the @lasertechs for “permission” to experiment

- 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.
- Purchase your own (must be laser-grade) - see our Suppliers List
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
Check the mirror for any dust or scratches, and clean if needed
Laser Control Software
The laser runs on software called Ruby
The induction video above covers the key steps in Ruby, more details can be found here.
Ruby uses colour palettes to assign laser actions, you can download files for popular vector software below:

– Inkscape - Inkscape settings.zip (11.3 KB)

Resetting Your Ruby Password
On the Laser PC:
- Go to Desktop / Reset Ruby Password
- Enter your email
- It will confirm you’re found and your temporary password has been set (or say not found).
- 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
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.
- 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
- 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).

|Users required to use approved materials only, correctly set speed & power settings for the material and never leave machine running unattended. CO2 fire extinguisher provided.
|Exposure to laser light
|Machine enclosed and lid fitted with interlock not to be overridden, according to Type 1 laser regulations.
|Servicing restricted to authorised and trained personnel.
|Users advised to use approved materials only. Strictly no PVC or polyurethane foams.
- The fume and dust-control systems must be properly maintained, tested annually and the filters changed according to the manufacturer’s instructions. Used filters should be sealed into strong plastic bags before placing them in the waste.
- Cleanup and machine maintenance must be performed as described in the induction
