Fri Nov 9, 2018 (new doc started for Nov 12)

Agenda

1. Fix extruder on Sara’s
2. Boone Adkins
3. Yes vs. No pics based on existing “Quality Control List”
4. TODO: detailed nstructions on JB Welding the frame
1. Yes & No
2. Use a copious amount
3. Also note the following:
1. 50/50: should not be gummy (should be hard as a rock)
2. Mix it so it's TOTALLY uniform: perfect gray color. no streaks else it's not mixed properly.
3. don't do super big batches
4. Use Acetone to really clean the frame
5. use sandpaper on the edges to it can get the friction right and stick very well?
6. Can you rip it apart with your hands? (how many pounds of force is OK? Aiming for 50-100lbs of strength)

5. TODO: for remote builds, have people make frame beforehand, and take pictures to verify

​

​

Sara

Notes

• https://docs.google.com/presentation/d/1rUhTMleIRipqhow2xcj9W2i2JxVswxyEp-P3yOgWDPg/edit?pli=1#slide=id.g44b829b5a0_0_0
• Undecided: how do you balance these tensions in the workshop design?
• New builders are not qualified to do quality control
• Cannot scale unless new builders do quality control
• Need instructors, but how many compared with # of builds
• Compare these 2 workshop designs:
• 3mm Printer:
• Heated Bed Temperature: Do 70 degrees, not 50. Makes things stick.
• Use .ini file on Marcin’s Log -- some config things have changed
• Two things to note:
• When you screw in the nozzle, and the heat break, you need to be careful…???
• For the neck, you need to be careful of…???
• For retraction settings, this is what’s happening…???
• * gear pulley attached to motor is actually quite difficult.
• * there's just no way to tell. you have to do it again. this is something we have to learn.
• * why it's difficult: stepper motor has a ring on its face. can't figure out how tall it exactly is. where do you measure it? from the bottom or top or w/e??
• 2.85L for the mirrored, 2.85R for the regular, DO NOT USE A 3.0

Updates

​

• Matthew dropped off his printer.

​

Notes

• Make product lines for target customers - such as students, schools
• ASk students on top 100 things that parents
• Ex - doorstop for school
• Framing: school saves $$ available for student education
• Can motivate schools that already have 3d printers to participate in design jams
• Other examples: plastic binders, pencils, pens, crates, organization drawers, bookshelves, geodesic greenhouses, worm bins, composting stuff, stackable food pots
• What is the break-even point for schools -- how long do they have to be running to start generating savings?

Thu Nov 1, 2018

Agenda

• Stephen Kaiser Followup

Action Steps

1. ​

Sara

• 4pm: Go to harbor freight
• Get acetone
• End stop cable research
• Investigate Eventzilla registration issue
• Begin setting up workspace for Friday certification
• Table layout: confirm -- does this layout actually work?
• Test the heat tightening (must be tight so that there’s “no gap,” but… there is… a tiny tiny gap because it’s butting up against the heat break and not the heat block, therefore use a torque wrench to measure the tightness) see “step 7, step 12” in titan aero assembly… do not trust “step 5” picture… because nozzle ‘looks like’ too close to heat block, when there *should* be a visible gap..of around .3-.4mm
• Test the cutter for PEI
• Test hacksaw for 3mm rods after purchasing from HF
• Duplicate control panel drilling template
• Test replicable box ideas - 14”x14”x4” - maybe a little bigger?
1. Find out what similar sizes are standard from ups/fedex/usps
2. And any cost difference between those sizes
3. Newspaper infill/wrap

Alex

• Follow up with Matthew about finishing printer (finishing an extruder)
• Print Carriages and Cable Holders
• Search for heatbreak on Amazon.

​

Marcin

• Start printing parts
• Post the London Workshop on FB and email list
• Setup of angle grinder chop saw
• Print hack saw holder

​

Notes

• What is changing?
• When priorities shift - to kits -

Updates

• Received z probe shipment; now just missing heated beds
• Found: 2 sawhorse purchase for $20
• Made placeholder for 3d printer workshop inventory

​

Notes

• Tool List

Blocks

• Sara Printer #2 not working with 2.85mm filament
• Partially extruding
• Check1: update ini file to use 3mm fila, review retraction settings?
• Check 2: generate gcode w/ 3mm settings
• Check 3: try using 200% for extra power?
• Check 4: hand feed, and see if it oozes out “as it should” (easy, uniform, thick as normal, and rushing out easily)
• Check 5: extrude through Cura (look for clicks)
• Is it stuck? Somewhere… maybe it’s a filament issue. Or the nozzle has stuckage.
• Check 6: extrude through screen
• Maybe the g code is messed up?
• Zprobe end stop cable question
• Clarifying: what are we doing for SF?
• Moving forward, unless Kit Certification and Build Certification goes FUBAR
• Sara confirm that she sees Tool List and can do Harbor Freight Run

GOVERNANCE MEETING AGENDA

1. Adopt [[Standup Protocol]]
1. Appreciations - Alex likes posting updates, and focusing on Blocks. Sara - appreciates goal of 45 minutes
2. Clarifying Questions - To Do items change - Need Work Meetings
3. Crosstalk - Alex - standing up is ableist; some people don’t have energy. Careful deliberation not allowed if standing up. Schedule special meeting if longer discussion is needed. Sara - commonly situations that are not practical. Standing is suggestion rather. Public spaces - don’t facilitate standing up. MJ - Stand up when at home but not in inconvenient places? If tired or in a wheelchair - not. Counteroffer: If there is a block that takes more than 5 minutes - let’s schedule time after standup. Also: a protocol for making sense of something that happened (later in agenda)
4. Restatement
5. Vote - 5-5-4 S-A-M
2. Adopt [[Work Log]] standards
• Appreciations - Alex - scalable is good. Sara - important for efficient meetings - just linking to work product. That helps stay accountability, ex [[Printer Log]]
• Clarifying questions - Time when log is ready for review? What level of detail.
• Crosstalk - Wiki organization is an ongoing job. Convention is modular breakdown of 50 machines + dev template.
• (Date, Link to work product, one-click-access to work product, use “common terms”, Timesheet, Format is =top-level heading for the date=, Timesheet on TOP.)
3. Adopt personal weekly [[Scorecard]]
4. Circles & StrategiesClarify parts of the org into “circles” (ops?) and clarify the strategy of each circle. Marcin decides the strategy for each circle. A strategy follows this pattern “We will do X at the cost of not doing Y.” Strategies allow fellows to make decisions about what to prioritize using their own judgment, leading to shorter meetings and greater clarity and better decision-making. When shift in stratgy is made, it is made explicitTension: Shifting priorities makes it unclear when things change and whether things have changed or if something is “an exception.”. Would like more clarity so I can decide how to prioritize my work on my own. Intent, data that caused the change. Ongoing dialogue.

Here are some proposed circles:

• OSE CIRCLE - vision for the future (GVCS, post-scarcity, extreme manufacturing). Main org strategy.
• Machinery - (create materials that support accessibility to 3d printer, even at the cost of not moving forward on the microfactory or... )
• Product - (6 hour workshops for OSE clubs, schools, makerspaces, and makers
• Traction - How we reach customers. Opportunities & channels & marketing & market research
• Community - ose developers, true fans, followers, potential contributors ()
• Proposal - do this for governance meeting.

​

2. November Stipend - Proposal

Need money to do work. How much is doable?

​

* $500-1000 plus profit from work, paid on Nov 15 -

*$2300 in bank right now, $800 accounts receivable matthew, $3500 CUHK in 1-2 weks

*In 1-2 weeks we have $5800

*Alex Will keep it to 40 hours

*Forecast - $1500+2500 from Ontario

​

​

Fellows Responsibilities Clarification

Clarify expectations on how we spend our time.

​

Tension: this was clear before immerision training, but not after. Need to make this sustainable and healthy on all fronts.

* Before: 100% 40 hours: 25% Workshop, 75% Marketing

* Currently?: 125-135% 50-55 hours: 30% workshop development (product) 30% workshop prep (product) 20% traction 20% machinery & community 20% workshop (product)

* Proposal: 100% 40 hours: 40% traction, 40% product development, 20% workshop (product)

​

3. Structured Standups

Try adhering to this structure to shorten meeting length.

* Check-in

* Updates

* Sense-making - centering 1 question, go around in a circle twice.

* Strategic Decisions - use governance style

* Tactical - ask "what do you need?" -- and person says what it is they need to do their work

​

​

''Do not''' make major decisions during updates.

'''Do''' separate sense-making from decision-making.

'''Do ''' share updates before sense-making.

'''Do not ask for significant follow-up questions or share reactions during updates'''

​

Expectations on Individual Prioritization

* fellows decide what to do

​

Honor Labor

* can we make this a value?

1. Title for the Agenda Item
1. 1 paragraph description of the proposal
2. include tension it is addressing

* the chopsaw or hacksaw? (link to hacksaw is… in an email somewhere?)

* (hacksaw 3mm & 8mm rods… they can always be cut if in trouble)

HAPPY HALLOWEEN!

• Sara fixed her printer issue by running at 200% -- this seems to give more power to the motor and prevents the stuttering that was causing failed prints
• 3 PM PST / 5 PM CST meeting with Russ today

Notes

• What is changing?
• When priorities shift - to kits -
• Priorities are not clear
• Workshop Instructor Training
• Detailed build guide lik
• Why this is a priority it is unclear?
• Sara can build it
• Teacher workshops?
• CLARITY: KIT PRODUCTION IS ABSOLUTELY NECESSARY TO ANYTHING THAT WE DO
• CLARITY: HOW GOOD? SO ANYONE CAN REPLICATE IT AND START BUILDING KITS
• CLARITY ON MANUAL: MISSING PARTS OF PROCEDURE, MISSING PARTS OF QUALITY CONTROL
• Sara: stick to things. Alex: I disagree with this. Marcin: both
• In startup mode, with new info, we must change action
• Prep:
• Little chop saw: will this work or not? (hack saw is not doable w/ 4 kits)
• Use the wire cutters to cut rods: does this work? (signs point to maybe not)
• Table layout: confirm -- does this layout actually work?
• Test the heat tightneting
• Cutting PEI for smooth edge
• Test the cutter for PEI
• Oakland - 4 spaces - large bedroom (not), studio (shared with painter), backyard. Only doable when not raining. 4x8
• Do all the steps in the https://wiki.opensourceecology.org/wiki/Kit_Certification#Certification_Process
• Kit Build Manual - Take Photos of everything
