So the power just went it the messy room.
Lights still working.
This fuse tripped.
It wouldn’t go back on.
Turned the extraction off. Turned the sockets with devices plugged into off. (3D printer and laser cutter extension)
Then the trip went back on.
The 3D printer works.
Think the fuse on the multi plug for the laser printer/extraction/ PC has gone as none now work.
Everything else on the space is working. All rooms.
Don’t want to fix the fuse or turn the extraction on.
Top work on fault finding- First thing I would check is the extension lead as it’s taped to the floor. Has someone squashed it ?
Courty
That extension lead can easily be taken out of the circuit and main extraction plugged back in socket beside it. People have been turning the main extractor off by its control panel anyway (as I discovered yesterday when the room filled with laser cut fragrance).
If it keeps tripping that’s a sign of a short (apologies for stating the obvious!)
Ha. That was my first thought too.
Dunno. No longer at the space.
Frank checked the fuse in the extension lead for the laser cutter and it was broken.
But was reluctant to put it back without knowing what caused it. Without a @Courty check first.
Probably something wrong with extraction. That blew the fuse and flipped the fuse on the board off.
Uneducated guess work though. Probably needs someone more qualified to fix
Simple answer to this…
This problem happened before and the reason is because the Laser Cutter should not be connected to an extension lead, it is a power hungry device, it should be on it’s own dedicated circuit.
Last time it nearly melted the extension lead, plug and socket, they were so hot you couldn’t touch them.
DO NOT PLUG THE LASER CUTTER INTO EXTENSION LEADS
To add to that, the power cable on the back of the machine is an IEC C19 16A rated connector, and indeed the spec of our machine is 16A at 230V for any tube over 60W, yours is 80W running at almost 100W output.
So in other words, attaching a 16A laser cutter, plus 1-3A of computer and a fan of unknown power consumption is most definitely over the 13A rating of that extension lead, and the fuse in it, which contributed to the trip.
As a further recommendation, a dedicated circuit was installed for the laser cutter at the time of phase 2 construction, you should probably fit a ceeform/commando socket for the laser cutter to use and buy a suitably rated 16A C19 to Ceeform/commando cable.

Did realise it was that hungry !! Yes it should be on the dedicated 4mm with a commando ! 16a will be peak but that’s too high for a standard socket…
Courty
I think given that I’ve never seen on on a Commado socket it would be okay, but the value is this accident which has now happened three times at Makerspace won’t happen again.
is the socket that the laser plugs into on the ring main with 2.5mm cable?
would it be an idea to run a dedicated thicker cable (with its own rcd on the consumer unit) to cover 16A
or is the 2.5mm adequate?
Also that breaker that tripped was a 32A one from the picture.
It’s been done just need to power it up.
Will try and find time to do it as soon as possible
This has been done. The laser cutter, pc monitor and extractor have now all been separated and are now in their own socket.
Ana and Frank have tested and all working perfectly.
Thank you @ana and @frasco
Your welcome.
oh sorry, I wasn’t excluding you. It was completed before your response was written.
I was just being cheeky 
There is a special dedicated ‘clean’ cable running to the space behind the laser that was intended as a supply just for the laser. like @joeatkin2 says, we’ll get this running on the same phase as the messy room ASAP and that will solve any potential issues instantly.
I’m all for putting it on a Commando or direct connection as it gives max power to the laser without compromising performance or causing voltage drops.
Courty
Isn’t this what it’s already connected to though? The laser socket is a dedicated radial on 4mm. Or is it not on its own breaker? The labelling system was a bit obscure last time I looked.
It might be on it’s own radial, but it’s on the same breaker as the rest of messy. The Ultimaker went down with the Laser cutter.
It’s not working yet.
What is not working?
