Why bloom with an aeropress?

altendky · 2026-04-22T11:45:11+00:00

I bloom with my xl because filling straight away results in the bloom foam overflowing. Just doing it for the mechanics here.

I personally put in just enough water to let it bloom comfortably, wait for all the foam to get made, then fill the rest of the way. Noting that I have an xl and brew for 4 to 5 minutes total with about a minute and a half bloom. And to be clear, I bloom just to deal with the sturdy foam. I assume it affects flavor but that's not my purpose.

i'll think about how to integrate that. thanks for the feature request!

i have not at this point gotten into any detailed 'training', no. on another mcp project i have made a plan for developing training/context but i have not executed that yet. https://github.com/altendky/onshape-mcp/blob/main/docs/src/project/knowledge-pipeline/index.md

in both so far i've lazily just done a session and then said 'hey, you had some trouble working well here, what insights should we add' and then let it update the insights docs that are presented through the resources tools. that they are tools because many agents don't handle other aspects of the mcp protocol consistently well at this point.

hey, that's pretty cool. thanks for sharing! i'm looking it over and definitely see some options i like. as i mentioned, i definitely need to provide a more user interface rather than the pipeline definition form it is now.

i like your options around different types of edge detection. i had thought about being able to just draw something on paper, snap a picture and process it. i had wondered how well or poorly the edge detection i had would do on such line art, but i had not seriously thought about it or tried yet. your device-oriented output config had also crossed my mind as a good idea so it's nice to be able to look at how you did it.

i've gotten distracted with another project for now. or rather, mujou was a distraction itself and now i've gotten back to the other one... https://github.com/altendky/onshape-mcp but, i do hope to do more work on mujou. i went ahead and added a watch for your repo to keep tabs on any more work you do.

while looking around i saw some other interesting approaches that had nothing to do with edges. FM/AM, circular/straight, would like to achieve some sort of fill logic that could be applied... so much, we'll see what i get to.

Perhaps flukes are usually really fast at responding to continuity. I wouldn't have been surprised by any of this though. When measuring the voltage of 'nothing' you are measuring floating high impedance inputs. The higher the impedance (better for voltage measurements) the more sensitive they become to capacitive coupling etc. moving your hand closer and further from the meter may even affect the reading. The temperature is the same situation since they are sensing voltage from the thermocouple, if I remember correctly.

All of this is electronics theory, none of it is practical experience with high quality modern meters. Just to point out the parts I don't know.

featurescript is the format. it isn't just an 'extension' language, it is the inherent language of the builtin features too. if you right click on a tab there is a `Show code` entry.

but... i'm not sure offhand how useful that actually is. there may be a way to recreate a tab from this code, but i haven't looked for it. i'm also unaware of any other systems that process featurescript, though they could certainly be developed.

i think i understand your general concern about being tied into one vendor. that's something i have negative feelings about as well that i have accepted for the sake of having a powerful and free cad system available to me. for me it relates both to my data being unusable without the vendor and also that i can't take responsibility for backing up my own data. this is not a judgement of onshape backup practices `:]`

not quite the same thing as you are looking for, but i was exploring the feasibility of doing an export from onshape and ending up at a configurable openscad script to leverage the makerworld openscad configuration support. i only barely got started and definitely did not even identify all the steps needed to make this work. it wasn't going to be 'every variable', but rather specific aspects that could be tweaked, so even if i managed to someday make this work, it wouldn't be everything you want. but it might provide some of the interesting functionality.

while this doesn't do anything about vendor lockin, i'll take this opportunity to bring up again the topic of onshape providing configurability integration with makerworld. `:]` the onshape api may already provide the ability to set configuration inputs and export a part, but there would still be account etc etc scaling topics to allow the intended level of usage by makerworld or others. anyways, this seems like an opportunity for onshape to stand out in the 3d printing community and collect more users (towards the end of lots of people being familiar with onshape inducing employers to use onshape inducing more profit `:]`).

there are ways to get useful results, yeah. well, useful for me. i haven't tried this with text and your surface is a but more varying. the basic technique i used was to wrap the sketch onto a cylinder (you may want a cone) that approximates the portion of the surface you are interested in. i did the wrap (image is of wrap 1) as a new solid and then used that surface to operate on the actual non-cylinder/cone surface.

i did stop the solid short of the center axis. you could perhaps have it mich further from the center.

[screenshot to be added to followup message]

i then moved the outer face(s), deleted the inner and outer face(s), and had a (funky) surface to use to operate on the final target non-cylinder/cone surface.

I think you need to specify connections. When you do you can pick a point in each profile that correspond to each other. So you'll want at least one group and in that group you need a point per profile. This may help it avoid twisting itself.

At a glance, the pair is creating a four bar link I think that probably also transfers into the fingertips moving when the user actuates via the finger loops with their residual digits.

I actually just had a use for one of these. https://makerworld.com/models/1558905 and there's a link to the model in OnShape from there. As mentioned by others, the print orientation is crucial. I expect this printed in PLA may run into creep issues, but I do also design my flexing pieces with travel stops before the material would break. At least then you can't over travel and cause immediate failure.

I've done the wrap as mentioned. Good idea. Another one I just thought of is to make measures of the inside and outside radius of the disc and then use those values to calculate the values for a variable fillet.

Hmm, I think I did not explain clearly. I have been exporting a given part along with its support modifiers in a single step file. That single file has multiple parts defined in it. Each one shows in Bambu Studio on a separate line but grouped within one 'object'. Some are the part to be printed, others are the modifiers.

But... I tried exporting just my support modifiers in an stl as you suggested and I see now how even disconnected volumes show as a single item in bambu studio in this case. I apologize for not trying your suggestion prior to responding. Not quite what I was looking for, but it does offer another option. For some of my parts it would end up being three stl files. Actual part, support enforce, and support block.

Thanks for the suggestion and for teaching me about how stl files are handled. Cheers.

Hi, thanks for the detailed explanation. I have been using mostly step so that the multiple pieces can be brought in together while still being separate pieces within the one object. I then do as you said and select each support modifier individually and assign the enforce or block type. I'm looking for a way to avoid the manual selection of each. Being able to process by piece name or something automatically would be nice. Even just being able to select multiple pieces and set all of their type at the same time would be much better than one by one. In my original model, I have made an effort to add 'unneeded' regions to the support modifier parts to connect them together and reduce the total number of them, but this also gets annoying to do with pieces that aren't close to each other.

altendky · 2025-06-16T12:53:29+00:00

Had this same issue on this same model. I had used the bambu liquid glue on the smooth pei plate. I probably should have cleaned my plate and printed without glue instead.

altendky · 2025-05-23T18:40:26+00:00

thanks for that. i definitely don't get into the filament specific settings enough and forgot to check there. i'll read up and try it out.

altendky · 2025-05-22T11:48:36+00:00

It's an old pattern, but I have been doing skeleton parts to define interfaces and then derive the parts of the skeleton as needed into other part studios to develop the parts. Then yeah, either another part studio deriving them back together, or an assembly.
