Plenum

The Plenum is a regular meeting of all people involved with the space to talk about things, and decide stuff.

If you have stuff to add, go right ahead! Please sign your points with your name (by adding a "--~~~~" after your text).

Preamble

• The Plenum is an institution to decide on what the space should look like, physically and in other ways, such as virtually.
• Things concerning the space should be discussed at a plenum.
• Everyone who's there can participate in that process, member or otherwise.
• Everyone can head a plenum, no need for board members to do that.
• Topics should ideally be announced on the Plenum wiki page beforehand
• The Plenum should be held in a language that everyone participating understands.
• Scheduling: second Thursday of the month at 8pm and last Sunday after the cleanup (which starts at 11am)

Next Plenum: Thursday, April 8 at 8PM

Topics for the Plenum

Disclaimer online plenum

Holding an online plenum is no new process and we will only do this do try it out during the time the space is closed. Doing online plenums in the future needs plenum approval. In case we decide to do online plenums in the future this acts as a proof of concept.

Projects & Groups update

Just a quick update from from of the groups meeting at our space, or other longterm space projects

• • I (Bernhard) got an idea of how to Further improve the CNC-Mill. I need someone to help me take off a few sidepanels of the mill to investigate some Stuff and take measurements i need for additional planning / calculating the Costs.

Say Thank you

Let's say thank you to those who did some awesome stuff for the space since the last plenum

Stuff from the past

What was discussed at the last Plenum? What's the current status of those things? 20210328 Plenum

• we still havent set a monthly budget for the workshop, even though it was already approved to have one.

after some talking we decided that 50€ per month would be enough to cover some expenses for broken / dull drills and other stuff.

Anything you don't feel comfortable within the space? What would you like to change or to be changed?

Is there anything that's bothering you?

• Just go for it. I want to upgrade the CNC machine, to precisely mill some aluminium. We did an Online Workshop and had a lot of Participiants. One of the key Questions was wether we could mill some aluminium.

I tried with a few Special aluminium tools and it seems to basically work but it is not precise.

However i noticed two things: 1: the Z-axis is very Wobbly, 2: The one sided Y-Axis is also very wobbly. -> Conclusion: they need to be redesigned.

My Idea is to spend about 1200€ in Parts. This will give us: Precision Ballscrews on each axis (2 needed for the Y-axis), Precision ground Linear Guidelines with ball Carriages, an complete Y and Z-Axis with Enough Stability to mill Aluminium, a high chance to even mill steel, Precision to about 0,02mm (high chance to be even better?!).

YES i know this is expensive. But i think the CNC-Workshop has shown that there is a lot of interest in having such a Machine (and we got a few Donations + i'm willing to chip in a few bucks if we run short on money). Also past buying decisions have shown that it pays off to buy some higher quality gear than the bare minimum needed.

Things to Buy

• The drill chuck in the Flott drill press is pretty worn and needs to be replaced. Bernhard and me searched for a replacemewnt and agreed on a Röhm Spiro-I. Cost for the chuck and arbor ~ €170 --Meier (talk) 07:40, 2 April 2021 (CEST)
• The drive belts for both drill presses need replacing. Total cost for 3 belts ~ €30 --Meier (talk) 07:40, 2 April 2021 (CEST)
• The Mill needs some Automation stuff to shut off the cooling air automatically. An electric valve, some Couplers and a Relais cost around 33€ together. BotoxBitch
