Notice
- 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.
Technical Specifications
Cutting area : 726 x 432 mm
Maximum cut depth: 12 mm
Maximum work piece height: 200 mm
Accuracy: 5µm
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:
-
Watch the induction Video https://youtu.be/4Gwtv9wWluI?si=YQbyJ7gNF52j8wSL
-
Add yourself to the waiting list for the practical induction
-
Book yourself on an upcoming inductions - list view | calendar view - you will need to login to see these
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:
- 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

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
Ruby
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:

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
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).

Risk Assessment
Click To Expand
**Description of Task** Using a high powered computer controlled laser burning process to cutting blank stock material such as wood and plastic to a pattern from a digital file.| Hazard | Risk Rating | Control Measure | Residual Risk |
|---|---|---|---|
| Fire | Low | 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. | Very Low |
| Exposure to laser light | Low | Machine enclosed and lid fitted with interlock not to be overridden, according to Type 1 laser regulations. | Very Low |
| Electrocution | Low | Servicing restricted to authorised and trained personnel. | Very Low |
| Harmful/toxic fumes | Low | Users advised to use approved materials only. Strictly no PVC or polyurethane foams. | Very Low |
Disposal
- 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
