Bit off-topic, but if you know anyone who is looking for some free
short/medium term studio space, Outer Spaces (
https://outerspaces.org/spaces/) have 4 very large open-space warehouse
units in Dyce coming up.
See you there :)
Hello there,
I will also cycle through BOD on this fine day, before ending up at the
space around 8pm.
My project for tonight? Trial software for designing furniture, and
calculate bill of materials. I have heard SketchUp might be good for that.
Anyone got experience with it?
Cheers,
Wouter

Hi all,
TL;DR: The Formlabs printer and Lulzbot printer really need some love. Let's spend a couple of hundred quid on each or throw them out. Can we approve a budget of up to 400 GBP to get it under control?
At the moment the printers are taking up space on a bowed desk in the lab and need maintenance to be usable for all.
In the case of both, we're at the point of use it or lose it. We're carrying a lot of stuff and there's nothing less appealing for new faces than "oh yeah, i remember when so and so used that successfully once, but we've got 7 not-really-working-3d-printers".
Let's get them moved to a dedicated, flat, stable workspace and invest in makign them usable and repeatable.
I suggest the old radio area that currently houses a boat anchor and TV, maybe combined with the table housing a sewing machine. The Desks are flat steady and reliable.
Formlabs (SLA):
This has sat unused for a long time as we're a bit afraid of it, but it's an outstanding printer which is easy to use and, if dialled in and cared for, should be a pull factor to the space.
Items/Parts/Hardware it needs are:
* New Tank
* Resin
* Wash / Cure
Tank: This is the thing the resin sits in and the print rises out of. Formlabs considers them consumable, and ours has sat with semi set / set resin in it since the last time anyone tried to print. [1]
Resin: the printer will take all kinds - I sugest we standardise on something cheap from Amazon[2] and get that dialled in.
Wash/Cure: Once someone has printed something, it needs exposure to UV to cure and IPA to wash off excess resin. Floating around there's an ultrasonic cleaner and a UV Lamp, but with the explosion of home resin printing there are dedicated products on the market that are affordable, we just need to match our print area in size [3].
Lulzbot (FDM):
The hackerspace has always been a bit crap at FDM 3d printing with printers that almost work. The lulzbot is currently in the liminal state of mostly working but being a bit disappointing. Every print I've done this year has had a warping/lifting issue [4] and layer 1 is a bit crap, I don't really know where to start on improving that.
It would really benefit from someone dismantling the hot head, cleaning it thoroughly and assessing if we need to repair/replace/update the whole thing or the nozzle or something else.
Similarly, it has mounting holes for a plastic enclosure to improve temperature regulation of the print area. Is this something we need? [5]
We have a lot of old filament that isn't well stored, which probably isn't a great starting point for good printing. Does anyone have any opinions on whether we can revive it, or are we best to chuck it out, invest in some decent storage [5] [6] and start from scratch? I lean towards a new and controlled start.
Computer:
Wipe it and restart//recover the root password and update.
Cura LE [8] is now under active maintenance again, get that installed.
Other Printers:
When these two work, let's give away every other 3d printer we have as 'free to a good home, no warranty' on facebook marketplace/somewhere else as a ploy to both clear the shelves and get people in the door.

Code the City have got their own building. Have been a couple of recent news stories that do a better job of explaining what + why than I could:
https://postabdn.com/historic-aberdeen-building-reimagined-as-tech-and-comm…https://aberdeenbusinessnews.co.uk/aberdeen-charity-transforms-empty-buildi…
I, and a few other people, will be there¹ on Saturday morning looking at what we can do for tech/IT/IoT stuff and hopefully making a start on setting some things up.
Plans include setting up network, putting in some LEDs, setting up Home Assistant, looking at control for the door lock and discussing what else it would be useful and/or fun to do.
I'm aiming to be there from 10:00 - 13:00. If anyone would like to help with any of this, or just drop in past and have a look round the building, you'd be very welcome.
Robert

I go the extra mile.
Usually because I missed the turning I was supposed to take.
I am thinking of heading down to space this evening for a couple of hours at about 8ish to move the 3d printers around. Anyone want to come play?
I could do with a hand moving that boat-anchor of a radio that's sat on the old radio desk if anyone's about.
Relatedly, can the owner of the big boat anchor radio receiver retrieve it from the hacklab or find someone to do so, it would be much appreciated.
Cheers,
Hibby

Hi All,
After taking a look at the Large Format Printer in the lab it will need at
minimum a Maintenance Cartridge. It is highly unlikely that any other parts
would be required as the print cartridge - if gunged up - can probably be
cleaned and made to work and we have additional ink cartridges if any of
the ink is unusable
LCL MC-10 Maintenance Cartridge ink Replacement for Canon MC-10 Replacement
for Canon imagePROGRAF iPF750, iPF755, iPF760, iPF765, iPF670, iPF680,
iPF685, iPF770, iPF780 (1Pack) : Amazon.co.uk: Computers & Accessories
<https://www.amazon.co.uk/LCL-MC-10-Maintenance-Replacement-imagePROGRAF/dp/…>
let me know your thoughts but I believe there is a high likelihood that
this would be the only required part
We have next meeting of python user group coming up on Wednesday with a talk + coding challenge on LLM delusions.

Then, explore practical techniques like RAG and semantic search to bring accuracy back to the forefront. Finally we will build a Streamlit-based semantic search tool to give you an introduction to the hands on experience of serving up the truth to your LLM.
