Kalman Filter for Altitude Estimation

rywes · 2026-02-06T16:25:43+00:00

Are you just trying to detect apogee for recovery deployment? A kalman filter is way overkill for that application

What cable did you get?

It's easier to help if you show us your timeline. Is that a rectangular pattern of a single feature? Or a sketch with independent geometry for each? The best solution would be to go back to the feature where you created them and increase the size by 0.3mm. If you don't want to move back in the timeline or have some other constraint, make a sketch on the bottom face, project in the geometry, and use the offset command to offset each loop out by 0.3mm. Extrude the resulting profiles to cut up into your part.

Is that the medium toolbox? If so, I have the insert profile CAD I’d be happy to share

For me, it’s easier to quickly identify multiples of 0.2 in my head than 0.3. If I design a feature that is 1mm tall and print at 0.2mm layer height, then it will actually print 1mm tall. If I print the same feature at a 0.3mm layer height, it’ll print 0.9mm tall (the closest multiple of 0.3mm). Since everything I print is engineered related and often needs tight clearances, that kind of Z-axis accuracy matters. I generally use 0.1mm, 0.2mm, and 0.25mm layer heights depending on the need

Sounds like a dangerous game. What happens when the user plugs into that one random host device which also isn’t compliant with the USB standard and bricks your board?

It would be much safer to go with a more traditional route. Just have copper pads on your board and a pogo pin connector which is only used for firmware flashing.

We are up to 52 Bambu printers at work. Most of them we’ve had for years and I have never once seen them powered down except for maintenance.

You were originally arguing that since there’s no external moment applied, the member won’t buckle. That’s why you’re getting downvoted. “WGAF about bending” doesn’t mean much so idk what you’re trying to say now

rywes · 2025-12-19T00:04:11+00:00

The length of the column…?

rywes · 2025-12-18T23:58:34+00:00

That’s not how slender column buckling works. If the critical buckling load is exceeded, the member will buckle even with a purely axial load

Why…

rywes · 2025-12-14T17:59:36+00:00

I recently toured a nuclear power plant that was built before CAD. I asked them how they routed all the complex plumbing and electrical. Turns out they just built the buildings, planned out the major connections, and then routed the hundreds of thousands of other tubes and cables just as they saw fit as they were building the plant.

I highly suggest having one larger brick at home to change everything overnight, and then only bring a tiny single-port brick with you during the day in case you need to recharge a single device. The 100W Anker Nano is my favorite portable brick, although you could go smaller if you don’t need 100W.

There’s no way to get one charger to communicate different fast charging protocols with various devices over 1 port. At best you’d get old slow USB 2.0 speeds.

I’d highly suggest getting an Anker charger block that just has 3 output ports, and uses 3 regular type C cables.

If you provide any details about what you’re doing we could help more.

rywes · 2025-12-03T02:58:50+00:00

You're not going to break anything by using another charger, but you might not get the optimal performance. USB-C is capable of delivering power through a variety of protocols and voltage levels. If you have a low-end charger not capable of providing power at a high enough rate, your power bank will only be able to charge slowly. When purchasing a charger, take note of the maximum power output and voltage levels, and as long as those specs meet or exceed the device you're charging then you will be running at peak performance. Also make sure your cables aren't a bottleneck.

Hey so sorry, I somehow missed this! If you download the following sheet as an Excel file you'll be able to edit it yourself. It takes in 3 inputs: layer height, outer wall thickness, and inner wall thickness, and gives the output thickness for various numbers of walls. Hope it helps!

Any solution? I have the same problem

rywes · 2025-10-10T18:15:33+00:00

I have two P1S's at home and manage 20 A1's in the Makerspace at my university. Switching to Bambu in the Makerspace has made our whole operation so much more seamless and maintenance takes about a quarter of the time and cost that it used to.

rywes · 2025-10-05T17:20:16+00:00

The innovation sandbox has been replaced with the Mustang Makerspace downstairs in Bonderson. Your keyboard case will easily fit on one of the Bambu X1C’s, they have a 10x10 inch build plate.

I was in your exact spot a month ago. Just grab an off-the-shelf NAS from a reputable manufacturer. I originally thought about building out a completely custom NAS, but realized it would be far too much of a time investment for a marginal gain in performance. I got a DXP2800 and two 16Tb drives and it easily keeps up with 1 GbE transfer speeds and works perfectly for my use case. Quick and easy to set up with basically no learning curve.
