RolesRole: maintenance technician
Practise diagnosing and fixing machines, safely
Find out why a machine is failing from its data and history, isolate it properly, fix it and prove the fix worked, all on a 3D machine in a simulated plant.

A real exercise
The press on Assembly B stopped mid-batch. The line still powers up, but the press head won't move as it should. Is it the drive or the tooling? You lock the line out in the right order, read the drive's signals, and tell the maintenance lead exactly which part to order.
How it works
Every exercise follows the same rhythm as the real job: a problem arrives, you investigate, you act, and the simulated company responds.
- 01
An alarm goes off
Machine data shows something is wrong.
- 02
Investigate
Read the data, check the maintenance history, ask the reliability engineer.
- 03
Work safely
Lock out and tag out before you touch anything. Then inspect and measure.
- 04
Fix and record
Repair, verify, and write the work order the next person will rely on.
What you practise
Concrete tasks taken from the exercises on this page. Each one is done with real data, under real constraints, inside the same simulated company.
- T01
Read machine data
Vibration, temperatures and other signals against their limits.
- T02
Use the history
Past work orders often hold the answer.
- T03
Lockout/tagout
The simulation refuses to let you work on live equipment.
- T04
Root cause, not just the symptom
Fix why it failed, not only what failed.
What you get
Experience you can point to.
- 01
Safe habits
The safe order of steps becomes automatic.
- 02
Better diagnosis
Practise a methodical approach instead of trial and error.
- 03
Ready for the floor
Arrive on the job having already handled a breakdown.
The tools you work with
Working tools, not screenshots. They read the same live data as the rest of the simulated company, and what you change in one shows up in the others.
- 01
Machine data
Vibration, temperature, cycle time and throughput per work centre, over time.
- 02
Work orders
Work orders, repair history, spare parts and who is assigned to what.
- 03
Capacity
Load against available hours per work centre, with overtime and offload options.
- 04
Job sequencing
Order released jobs by rule or by hand and compare how late each plan runs.
Six levels, one exercise
Start by watching it done, then take the hints away one step at a time until you can do it alone.
- L1
Watch it done
The exercise solved step by step, with what each step changed.

A debrief after every attempt
You see what went well, what did not, and what a stronger approach looks like, based on what you actually did.
Every action, in order
What was checked, who was asked, what was changed and when. Nothing is overwritten.
Scores by skill
Each exercise scores the skills it was built to test, from what was actually done.
Weak habits, flagged
Poor patterns in how the work was done are flagged, not only wrong final answers.
A replay of the attempt
Step through the session as it happened, with typed personal details masked.

Do I need tools or a workshop?
No. Everything happens on 3D machines in your browser.
Does it certify me?
No. It is practice, and it does not issue safety certificates. It helps you follow what that training teaches.
