Its very quiet top of the line Honda
I’ve asked about electricity. I suspect we wouldn’t be allowed to use a generator, for noise and smell reasons (no matter how quiet it is)
@SarahJ if nobody else fancies it Ill give it a go - depending on what is decided.
Im thinking it will be easier to talk things through in person. Is anyone about tomorrow evening?
Although Ive used a laser cutter before I could probably do with an induction - @tomnewsom can you help?
@Dermot are you the man to talk to about materials?

Laser inductions will resume once we’ve done a refresher for the existing inductees (to include lens care/cleaning). That won’t be in time for Saturday, I’m afraid.
Oh ok… I just figured ye needed a hand on Saturday. No worries.
@Members is anyone else interested in helping out on saturday? W need a good few more people to join in if we’re to go ahead with this.
What specific model Joe? If it’s very small and quiet we might be able to get away with it.
We wouldn’t get away with it I’m afraid :-/
Fair enough
Car battery and inverter?
Great. I could meet up this evening at say 8:30.
Not a crazy idea. @adamjpage mentioned that he had a decent inverter and some big batteries. How many watts does the 3D printer pull?
I’d be very wary of plugging anything electronically sensitive into a cheap inverter which probably won’t generate a nice pure sine wave…
What power supply does the 3D printer use, though? If it has a plug in transformer we should just replace that with a DC to DC converter.
We have a bit more information:
Fair times: 11am – 4pm
Set-up times: 9.30am
The Norwood Road stalls will be located along the stretch of road that runs between the entrance to the Bath Factory estate (next to Costcutter) and the junction with Croxted Road.
Unfortunately power has proved to be a real problem – so if you have any battery powered lights please
do bring them along - and feel free to decorate your stall with festive fittings. A prize to the most garishly decorated stall (probably a mince pie!).
(my emphasis 
)
There’s also contact nos. etc which I will pass on to the volunteers.
This is the spec of the UM2 psu. DC 24V around 9 amp.

Using the Heat bed will be the more power hungry without the bed DC 24V 3 to 4 amp should be enough. Glue stick applied to the glass or blue painter’s tape and no need for the bed
Most supplies in a 3d printer are 24v/12v heaters and steppers and a 3.3v/5v logic supply however I really would not like to do this as the ultimaker is a consumer product. Also we talking high current on the 12/24v supply so with out building it and doing a decent burn in test which we do not have the time to do so honestly. I think the best would be to put the ultimaker on display and run a video on one of those donated DVD car screens we have at the back.
Trying to 3D print will be a waste of time, it will be too cold for the print to stick to the bed.

Modern switch mode psus don’t normally have a problem with scrapey supplys as the input is usaly a bridge rec
I have got some voltage converters that will run it directly from a battery
