CEB Press, Power Cube
Updated drawer guides worked great and were simple to assemble (compared to nightmare last time). New controller + solenoid valve mounting by Nick was great. Welding went smoothly and quickly. New power cube was fabricated - including the hydraulic reservoir - entirely with novice builders, including design and build collaboration. 2 new torching stations were set up and used. Full time time lapse worked well. Participants were great - not a single sour grape.
Blocks in certain steps prevented me from helping others properly. Nightmare for me fixing up main cylinder leaks. Nightmare for me with main cylinder mounting, in that the press foot ended up being 3/16" too high and had to be ground down. Bolt hole for connecting frame to primary arms was not correct and had to be torched. 2 parts missing from materials order. Screws for engine were unidentified. No charger on the power cube. Too few people signed up for the workshop. 2 welders broke. Electric impact wrench broke. Mechanism needs to be added so right angles do not pinch in during welding.
CNC torching with our own torch is a necessary pre-requisite to get entire job done and to provide work samples. Correct the drawer guide space issue, and update CAM file for the upper tab of chamber plate. Put go-pro cameras on peoples' heads for first hand footage of steps. Add another time lapse camera on a tripod for 2 total. Add internet and overhead projectors for instructionals in the shop. Add a dedicated computer for taking notes and for real-time instructionals production - where people go to the computer to report steps after every task. Add one or more auto upload camera for real-time instructionals - possibly an app where pictures are uploaded on a per-module basis. Add a Free Worskhop option to marketing - with paid training day. Develop open source welder and open source power tool construction set to nail the equipment breakage issues.
Yes, I'll get the OSE Devs can work on CAD and CAM file update to CEB Press - it would be useful to create a CAM File Validation protocol in FreeCAD, and generate CAM in FreeCAD. Nail the CNC Torch with the Dev Team. Do Power Cube CAD and CAM in FreeCAD. Introduce Remote Documentation protocol to OSE Dev team. An open source go-pro would be a valuable addition to the documentation process - and a great case for applications of the 3D printer.
|***||Absolutely, with the disclaimer that people have to be willing to learn and troubleshoot on their feet.|
This event showed how much still remains to be done to produce a seamless event. The good part is we've gone so far already, in that nobody is carrying on Extreme Builds like we are, and other good part is that we can make this so much better still.
|3D Printer||Friendly, helpful staff.|
Not enough time, plus need step-by-step instructions, disappointed that did not learn anything about programming etc.
Get rid of the magnets. Fasten everything together with bolts/screws--no welding, no magnets. Creating plastic jigs for drilling holes, and get a cheap $100 drill press. Angle iron doesn't need to be quite so hefty. Magnets might be nice for optional plexi curtains, but nothing else. Please no magnets and no glue. Provide picture of assembly & assembly steps and wire harness diagram and connections. Hold a brainstorming session to improve design following assembly. This is OSE, after all! This should probably be a two-day course, not a one-day course--although perhaps if you lose the magnets and printable instructions, the units could be built in half a day, though.
|Not at this time||**||Not until it's improved. OSE seemed to be spreading itself too thin on this one.|
Open source should be about collaborating and improving on "free" designs, not building inferior "me-too" products. I would frankly rather have paid more for a lulzbot, that reflected far more design effort and better performance.
|Elie Chrôme||3D Printer|
the wiring was easier than I tough, I could also have a diagram laying around that would help
The axis assembly was a little bit messy. Not everyone looked at the wiki files, so it would be better if we have a good look at the wiki file right before putting into work . There could also be a computer in the shop where people can find Cad files/general information about part assembly while working so there is no time lost .
Defenetly the double Z axis , and the wider Y end part belt slots. Than , nee mounting design for the lolzbot mini nozzle.
Definitly! I'm waiting for a new SSD, as soon as it arrives trought the mail, I'll take the OSE developpers test!
New frame design are very interesting, I'm actually working on a wood frame and will defenitly build a thicker pvc one as well
CEB Press, Power Cube
Marcin's conversations before the day started were helpful and felt welcoming and inclusive. He was also very helpful when he was able to stop by and inspect our work, make suggestions, etc. Based on the movie, Reversing the Mississippi, it seems that this has improved. Two suggestions to improve even more: (1) a sign or a person to welcome guests on the first morning and have some breakfast stuff laid out somewhere if that's what the pre-course materials say. (2) Marcin needs to be able to orient people in the workshop and be as hands-on as possible, making sure no one is spinning their wheels unnecessarily.
If there is a machine needed for a client, I would really try to minimize the amount of prototyping that is going on and/or extend the time to accommodate prototyping. We designed a frame for a power cube even though this is one of the more highly developed products. Similarly, with the CEB press, there were numerous time-consuming modifications required.
In addition to the above: Give a tour of the farm, give a tour of the workshop, tell people where all the tools are and the logic for them being where they are (perhaps grocery store style aisle signs would help?), introduce people to a shop culture (including putting things away when done, labeling broken stuff, etc.), have updated documentation or check at the outset that it is relevant for the particular project someone is working on so time is not wasted.
It's not realistic to dedicate 10 hours/week to this.
|***||I'm not sure. It was valuable and even kind of epic, but I'd warn people about current levels of disorganization especially because the goal is very efficient lego-style modular swarm manufacturing. That's not happening yet from my experience.|
It's such a great vision and overall project. Just a monumental task that I will continue to follow, encourage, and support. My suspicion is that it will be key to make sure each participant has a good experience so that word of mouth is not ambivalent. I think Marcin would benefit from having a detail-oriented, anal, cruise director type person as a partner during the workshops.
CEB Press, Power Cube
getting hands on, working with other team members.
It was a bit disorganized, felt like not everybody could get up and running without asking Marcin lots of questions, but maybe it was just me, the drawer had no specific directions printed. I didn't know the first thing about jumping into the hydraulics or electric.
Is it a new build everytime for PowerCube and Press? Feels like this should be standardized and not re-inventing in some way each time, and then digital plans could be created that could be distributed on phones. Maybe I don't have the full picture here to make this suggestion, but I would love to be able to consult my phone and pull up any/all parts of the machines to get a better understanding.
I would have liked more exposure to hydraulics and electrical for a better understanding of the the full machine. I realize we had some setbacks so maybe that would have happened in a build with less issues.
I was also bummed about having to leave at noon due to transportation issues. I scheduled an evening flight based on communication prior to the workshop, but spent all afternoon at the airport rather than in workshop. I feel like Sunday (and the money paid toward that day) was mostly wasted for me.
Yes - not sure what all Developers do, but what comes to mind for me is creating content with full information around the build, that can be distributed digitally and easily pulled up to help in fabrication and overall big picture knowledge
Getting to work at different stations throughout the day and talking to others with different backgrounds.
It's a looong day, so better access to food/water and an area to take a break. There was the Hab Lab, but it was away from the workshop and going up there to take a break seemed anti-social or that I was skating out on doing some work since it was a communal build, and I wasn't just building my own. If I was just building my own, I think I would have been more willing to take rest breaks when I needed them. Definitely some stools to sit on while doing some of the assembly. Also, there were no wiring diagrams available for the electronics. We had already been working over 14 hours by this point, so that was a no-go for me to even attempt to figure it out at 11pm.
I'll start from the first part of the experience through the end with the understanding that the people in attendance are generally the type of people who figure stuff out, so some might be overthought and nitpicky: 1) It might be a nice touch to get a "welcome" email a day or two before the event to confirm it once again, since the location is a bit "in the middle of nowhere" and most of us came pretty far to get there. I had a small amount of anxiety that it might not happen 2) The morning of, there weren't any signs or anything where to go (or just to confirm, "yep this is the place". I just pulled into a remote farm, in an area I've never been to. Luckily, there were a couple of other folks already there, so I went to talk to them. I guess I'm used to most events having some kind of registration table or something. This was much more informal, which is good in a way 3) Which reminds me that we need to make sure people sign the waiver 4) The posting for the event said we would start at 8am, but no one (I was talking to), had heard from Marcin by that point. I think we started at more like 9am 5) The Hab Lab was a cool meeting place 6) The workflow of the builds: 6a) Seemed a bit on-the-fly as we randomly started working on an area of the build without knowing anything about that station 6b) It would have been nice to get some more instruction of what to do at each station, at the least, an instruction sheet at each station. The way it went down, people would move to a station and hear what to do from someone. This is kind of a neat collaboration thing, but we also had numerous times where we did things wrong and had to do rework. This was ok the first couple of times, but by 5pm it was not :) 6c) The electronics wiring takes a fair amount of concentration. This was very challenging at 11pm with no wiring diagrams on-site. 7) Tooling: 7a) Seems like a Dremel tool would have helped a lot for cutting the rabbet out of the heat sinks 7b) It would have been good to have some clamps (not these, but like these https://www.amazon.com/dp/B01M9IY5ED?psc=1) for gluing the magnets 7c) We also had some issues with magnet pockets on the 3d printed parts not having flat bottoms, might have been good to have a bit that could drill those out 8) The schedule was a bit long, maybe it should be broken into 2 days until the process is streamlined enough to make it work in 1 day at a reasonable pace. It took a lot of fortitude to continue at some points. The pizza delivery around 8pm lifted everyone's spirits a great deal and they said it was only about $30 for 3 pizzas 9) Learning: The event was advertised as "build your own 3D printer", but that's not technically true. We worked together to build parts of everyone's printers, and did not necessarily get to work with all parts of the printer. I actually had no idea which would be my printer. While that's fun, I did actually expect to go through the entire process of building every part of the 3D printer from scratch, and therefore, learn about each part of it. For example, I didn't mess with any of the heat bed or electronics. I guess my expectation was more of what I had to do with my X-Carve CNC router (http://x-carve-instructions.inventables.com/500mm/). In retrospect, it did take me about 18 hours to build the X-Carve, so I'm not sure how doable this would have been without the swarming approach, but it was not really marketed that way either (i.e., this wiki page calls it "Extreme Build Experience", but I don't recall that from the event posting. It does mention Extreme Manufacturing near the end, but I don't think I really understood what that meant at the time) 10) Machine design: 10a) I think it is, by design, for part reuse and teardown, but it is entirely possible to put the parts together the "wrong" way. This led to a lot of rework. It's flexible for taking the thing apart, but in reality, I'm hoping to not have to ever take it apart :) When I'm putting it together, I want to make sure I put it together correctly. I learned that rework during the build process hurts morale. Perhaps the parts could be designed keeping in mind that the builder doesn't know what they're doing, so it would be better to have it not be possible to put the parts together the wrong way (As examples, it can only be bolted from one side, it's clear which direction the part should face, etc.) Or perhaps the parts could have labels 3D printed into them. Not being able to put the parts together incorrectly actually seems even more important for this build approach because it can be a little unfocused, at times, with people chatting, etc. 10b) Too many magnets? I was one of the people who did the frames, so by the end of the day, my hands were cramping from trying to separate the magnets. 10c) The magnets didn't fit in the parts that well, and even if they did, the manner of inserting them was a bit of a magic trick as they often moved towards a bolt before getting them place. Perhaps we can make a jig for holding them or attach them before bolting? 10d) It seems the printer needs a cooling fan as part of the design? 10e) Is there a way to level the print bed? 10f) Maybe the parts could be designed or printed in a way so there is no overhang on the magnet pocket areas that caused the fitting issues we had with the magnets 10g) Figure out printer settings to reduce the "cleanup" work we had to do on the printed parts that had lots of stray artifact in the holes, etc. 11) Plan for people traveling by airplane to be able to transport the machine. I think it's possible to take them on the plane in a large box, but I didn't bring a box and was leaving on a Sunday and wasn't even sure where/if I would be able to get a box somewhere on a Sunday morning 12) Have lots of water available :)
Joined as OSE Developer :)
|****||Yes, but only if they are seriously interested. The workshop is (currently) not for the faint of heart. It's a long day and a lot of work, so in it's current state, it seems beyond a casual level of interest. But it is fun!|
I was very happy to be part of the procedural thinking process of the workflow
We took used pieces to produce our 3d printer and it make it difficult time wise considering we had just one day... Without that last factor using these part is a very good idea.
The workflow is something we were working on, so I think I've said what I had to say. Regarding the machine design I will have to use so i'll let you know later. The event schedule was maybe to tight, but I guess this has something to do with the fact that we were just two participents...
I think that considering the situation i'm in, the more intelligent way I can help OSE is in trying to develop connection in Montreal regarding OSE bay first trying to organise a workshop on 3d printer and maybe more. I spoke to my superior at the college and she's totally sold for the project, she's meeting the DG tomorrow to talk about OSE. So we'll see how this situation evolve, but it's surely a good start as it meets almost perfectly the goals the institution put in front of itself 2 weeks ago. This might be the beginning of something big, we'll see...
This project is truly inspiring, I've rarely seen such a purposeful way to react to the challenge our civilisation is facing. Thank you so much for contributing to the world in such a thoughtful way.
Collaborative brain storm worked great, less "gotchas" would have finished the build on time
Ironing out any caveats or "gotchas" in the build process (e.g mirror image axis vs duplicate axis) increased build time significantly, also not having all the parts readily available for the build (e.g some parts were bad/defective).
Lowering barriers entry to participation to attempt to obtain full participation and unlocking the synergy of group brainstorming
Sure I don't mind volunteering (on weekends preferably) but I don't think I know enough of OSE's internal workflows to suggest and execute improvements. I just went to one workshop but as we discussed, In that one workshop I definitely noticed these "gotchas" that consume a significant amount of one's time and bring to a stand still the the main workflow effort of the workshop for hours and the only way to fix that is to EXPLICITLY document the gotcha in each instruction step.
Printer shipping weight was 54 lbs + packing materials. Cost of shipping for me was ~$34.00 but if shipping to residential home probably ~$50ish
I got to practice a lot with welding and torching which is something I was looking forward to with this workshop.
I got out of the workshop everything I wanted.
Better organization for tools, more lighting, move tools out of workshop that are no longer working (laser cutter, etc) to free up space.
Yes, already OSE Developer.
focusing on the bare minimum tech. I actually valued not having CNC abilities
I think the lack of drawings or printouts for cutouts. Also, we were going in multiple different directions to start, but once we clarified our path things really zipped along.
build the same tractor again (also see log on the wiki)
Working on the development team already! In the near future, I would like to replicate in Colorado.
Depending on the person's goals, yes!
|Tractor||Great group of people. Excellent project.|
Maybe internet in shop would help check drawings and update documentation.
Workflow worked well. Lots of shared learning.
Yes, looking forward to possible automation projects. Hydraulic robot arm.
|*****||Yes.||Thanks for putting it together. Super fun great community.|
Amazing crew of team players. Better preparation and streamlining one after another of the many elements - such that it turns into a replicable Starbucks experience.
Lack of documentation and supporting resources to make the event better, and tools (CNC torch table). (complete build instructionals, exhaustive instructionals on many aspects of the build, insights, cheatsheets, details, Learning Station in the workshop, internet in the workshop, less cluttered workshop, more organized workspaces and tools)
CNC torch table; better scheduling to market the event 6-8 months ahead of time
Yes. By continuing to run ambitious monthly builds.
|Getting closer to viral replication.|
The overall experience, and a near finished tractor, worked for me. Do better: 1. Knowledge of how to get here, what to expect at the hablab, food/grocers/restaurants nearby. 2. A cleaner shop and better organized tools.
Not enough wood for the stove. Have a cord of firewood.
The old machines should be torn down.
Have a parts list for each part of the tractor. Have paper drawings in the shop. The workshops can be labeled as prototype or production.
The ose website is showing its age. The forums should be deleted. I took a look a few months ago, and thought that ose stopped in late 2013, until I found your youtube channel.
Yes, If the website is open to user updates.
I could add a cinva machine to the tool set
I suggest having an "ose academy" section and partner with a local college. Also, to have a "store" section and sell user documentation and the machines. You can outsource the manufacturing.
Hands on working with the great people I met there.,
Pre event learning tools/instructions
|I will work with lex city||*****||Yes|
This was an intense Building project that I was glad to attend. This is the type of thing that is a great fun but also educational.
The setting - the environment created at Factor E Farm is inspirational and empowering. Although not the focus of the course, I enjoyed a brief tour of some structures, including the Seed home, aquaponics greenhouse and CEB houses. Being able to work in a well-equipped and organized workshop also facilitated learning opportunities. I would appreciate the opportunity to learn more about some of the systems in place, or in development (waste cycling, food production, power generation, etc.)
Staying on site in the hab lab - being able to wake up, get dressed, eat, and begin the day with a meeting to talk about the day's activities was great. Staying with everyone else here really helped with camaraderie and enabled deep discussions in the off-hours.
Working beside experienced operators - I found it beneficial to work and learn alongside a number of people more experienced than I. Being able to learn a tool's operation from different people gives insight into universal best practices, and into tricks and different ways of doing the same thing.
Working on many different aspects of the project - I enjoyed being able to contribute to many different tasks and parts of the project.
Problem-solving - Although it would have been nice to have a true to life CAD with step by step instructions, I had a lot of fun and enjoyed helping to work out some of the innumerable problems we ran into during the build.
Sharing meals -
More ventilation and better lighting in the shop would be awesome.
I would include a suggestion in the registration confirmation emails, outlining some extra preparation, research and work that could be done before the workshop - maybe some how-to videos on using specific tools that will be used for the workshop.
Perhaps. Depends on my available time over the next months, and my ability to become proficient with FreeCAD, google docs, OSE wiki, etc.
|*****||yes||Had a really enriching experience. Thank you for doing what you do here.|
Loved the teamwork and working together. Perhaps print outs of each task that once a task is completed the team could find a new task with relevant instructions on it. (All pertinent data, could even be hand written.)
Spent a lot of time looking for tools. Initially it would be nice to have a map of the shop with the general categories of where everything is located, just like many grocery stores and large box stores.
More details would be nice regarding transportation to and from airport if it is available, exactly how the food will work (provide our own, someone cook for everyone with food provided, or volunteers taking turns cooking ). What is important is taking the mystery out of what it will be like as some people are hesitant to commit when things are unclear. It would also cut down on pestering emails asking questions. A list of food places close by (when it is stated it is in the middle of nowheresville, that may turn off some people so the knowledge that there is a bit of civilization not too far away. Perhaps a lot of this could be answered in a FAQ.
I certainly am interested in being an OSE Developer. I've got to get up to speed on Freecad. I can't do much until snow hits and stays which is usually sometimes in November or December in North Idaho.
Absolutely!! Awesome experience.
|I'd like to build the workshop tools that are used to develop machines and contribute in a more significant way.|
The ppl and the flexibility worked. A more organized space and more grounded expectations would serve to heighten that combined effect.
The bar was too high. Yes, I get the tedx concept. But I also observed faults that damaged the credibility of the project. Ex: incomplete cnc table, unreliable tools incomplete plans. Remedies : stabilize the design & shopspace, organize tasks and tools communicate early, often and thoroughly.... Since we addressed in situ, for which I credit Marcin's ability to temper ego in the name of outcome.
The intended workflow was adequate however the design, tasking docs, material and space were not supportive of the pace required. I don't want to harp on it but stability of design and order of space is crucial to sustained efficiency in working with enthusiastic participants.
Yes. I'm willing to support a stabilized design into replicability. Repeat a build. Build a workshop and repeat, train the trainers... Then microfactory distant rollout with... I've got experience, let's talk.
Yes. And I would set their expectations accordingly.
Thank you for your vision and the effort it takes to share it forward... I look forward to finding a roll in moving it... And I hope you are doing what it takes to sustain your self.
|CNC Circuit Mill|
CNC Circuit Mill worked on the first try, and the circuit produced worked on the first try as well. This is perhaps the best result to date - typically there is a bunch of troubleshooting that has to be done.
Schedule was completely messed up because I did not make it clear to Shane that we absolutely need his D3D Circuit Mill as a model to improve the speed of build. We failed to coordinate effectively before the build on the build instructions, so there were 2 cooks in the kitchen regarding providing build instructions.
Better software integration - we could not even install FlatCAM, though we did run Copper Carve and KiCad successfully. Copper Carve needs bed leveling integration still.
|Yes. Doing it full time.||****||Yes!|
Not five stars because we didn't follow the schedule. I felt like a 3 stars after the first day due to the missed schedule - until the spectacular result of BOTH mills working perfectly on their first try.
|CNC Circuit Mill|
Most of the machine's parts fit together well (no struggling to assemble them).
It would have been great to have an assembled model and visual/textual assembly instructions.
|7/12/2018 6:46:03||Bill Clark|
|CNC Circuit Mill|
Having an example machine assembled as an example to follow, time for banter, very knowledgable workshop leaders.
Fell behind in assembly process. I wasn't certain ahead of time that I was going to participate, therefore I didn't preview online wiki materials beforehand. The wiki for the workshop is thorough and could have helped.
For workflow, I find that when students are following a complex procedure, an explicit step-by-step method helps to reinforce process and assure student understanding. See example at https://learningwilds.net/learnd/node/23. For machine design, I mentioned that the carriages, motor mounts and other 3D printed parts could be redesigned as a single multi-purpose part to reduce the unique part quantity. That would be a good design challenge for someone.
Certainly, as an OSE fellow candidate, I will experiment with that workflow model as I develop my leading techniques and share it with others.
Perhaps making the 3D printer workshop a pre-requisite for this course would be a good idea. As the D3D 3D is simpler and essentially a sub-set of the circuit mill concepts it can help build up to the mill which relies on additional knowledge about electrical components, etc.
|CNC Circuit Mill|
I really enjoyed meeting the people and working with them. I know OSE's typical model is the extreme build. But I really liked the laid back feel we developed - typically that is more condusive to learning. At least that's what I've found teaching at the university - Stressed out students learn nothing, and calm students retain information. I think the workshop could be improved by having a more liberal schedule - but at the same time more strict in enforcement.
I think more coordination is necessary when there is more than 1 person running the workshop. At times, we (Marcin and I) were giving contradicting tasks, and burned up time because of it.
The software tool-chain needs to be completed and refined. Increased documentation, and I think a pre-workshop online meeting is a great idea to get people in the mind set and give them "pre-read" material
I'm working on the software and will be working on the mill and it's construction manual in the following weeks.
Yes - I hope to recommend it to friends when we host a worksho in Houghton
|I had a lot of fun.|
STEAM Camp only 1/3 of the time. Remote participant.
As a general introduction to machine design the workshop was very friendly. It is always nice to get in touch with other people that is also inspired by the ideas postulated by OSE. To make it better: more realtime media.
Media. First and foremost: sound. In several opportunities the conversation was carried out very dynamically among the onsite participants but one could not follow from the distance because it was not possible to hear what was being said. That, and the lack of images for visual stimulation resulted in my attention drifting away from the meetings. A further consequence could be that the remote participants will contribute a lot less in the whole process.
I stick with audio and video for the time being.
Not in position to contribute at the moment.
|Please, carry on doing what you are doing.|

Steam camp (remote)
i think, a general notion of the important things involved in the projects of the OSE, in particular, I found very useful the table of contents, the design guide and how to use it. to make that better, could be good to put more links of each subject for further investigation for remote people,
I think the internet connection is very important, for us in the remote mode was very difficult to follow what was happening in the workshop and in class, it could be very good if the OSE improves the internet connection so transmission does not fail, the other thing that can improve this is to have more than one camera so the remote mode can choose what to see in order to understand the class.
As a remote participant is difficult for me to know how to improve this, maybe involve more the remote participants in the software design... i don´t know really...
I definitely wold like to assist, may be as a tutor or something like that, or as a helper in the practical stuff, i Have worked as the guy in charge of summer and winter social camps (we went to small poor villages in chile to build basic houses) on a school in which around 300 boys and girls participate for 10 days, maybe y can share with you the programs, schedules, ways we have to make it work, we had a good organization under it, but still I live quite far in chile...
yes, but presential
|i am grateful of the camp and the knowledge the OSE staff has shared with us, thank Marcin!!!|
Microfactory STEAM camp (remote participant)
Very interesting topics, and very practical and useful knowledge.
For remote participants, there were at times problems with the connection (not your fault, of course)
Only one point I expected a little different: for the classroom lessons content I expected at least a few formulas
I'm still not sure, but possibly yes
CEB Press, Power Cube
Brief orientation on the first day and feedbacks on following days were very helpful.
I wish it was bit more organized and well prepared.
Current design of CEB press is too heavy and need to reduce the weight where it is not necessary
Yes, joined as OSE Developer
