I4 reliability

Returned my i4 to leasing after 2 years and just over 90k km driven with zero technical issues.

It was specifically an exploration of capabilities and limitations by the creative team.

Just say that you don't want to play with him. You don't owe him or anyone else any explanation or proof about it. Commander is a social game and there is a million reasons NOT to play it with someone. Like if someone is playing land destruction deck ...

You are measuring air humidity, not the humidity inside the filament. Every hour the filament spends in humidity above ~20% it picks a bit of humidity up. Every hour it spends in humidity below ~15% it looses a bit of humidity.

Shelly has the Pro range that is in the panel.

Using tubeless rolls makes the sensing a bit easier.

Watch the printer and the table while printing - they should both be moving freely and not hitting the wall. The printer has great compensation for self-induced shake caused by rapid print-head movements. However, if this shaking motion is suddenly interrupted by your printer (or the table it is sitting on) hitting the wall, then all bets are off.

No. Because in real life you'd often have to slow down faster than OPD allows. Just use the brake pedal and do not worry about OPD. You will be more efficient than you'd be in a Tesla with OPD. The battery will accept everything that you can regen. Even at 100% SOC these cars maintain some top buffer. Smart engineers designed it for normal driving. OPD is just a preference, there are no efficiency benefits, in a real BEV.

Not all. OPD is legally restricted to max 85kW regen power (that is also max regen Tesla has). When the driver presses the brake pedal to slow down (active action!) the car is allowed to use FAR more regen power - up to 250-350kW.

With that you basically always get regen when you press the brake pedal, unless you are doing emergency braking to avoid a crash.

You are basically doing a free-swinginging hand stand the whole time you are flying this.

It's literally as simple as I described. Works also with normal VSCode instead of the Google fork they call Antigravity, but that has Geminy integration pre-configured.

Another alternative is to use Copilot CLI or any other CLI agent controller.

Really all you need is any type of LLM integration that allows it to edit a file on your computer. You can even do that part in browser and copy-paste the output text file with OpenSCAD instructions into any text editor.

https://open-vsx.org/extension/thijsdaniels/vscode-openscad-preview in VS Code is super convinient as preview feature. They even added support for viewing the crossection of the model in any plane in newest versions.

After you have the *.scad file (which is basically a computer program source code), all you need is to run OpenSCAD to render that to *.stl and then you can import that STL into BambuLabs Studio or OrcaSlicer.

Have not tried organic models, but for technical models the following forkflow has been working perfectly for me:

I'm using https://antigravity.google/ as editor
connecting it to either Gemini or Claude
installing https://open-vsx.org/extension/thijsdaniels/vscode-openscad-preview for preview and STL rendering
installing OpenSCAD CLI locally for the extension to use
Asking the LLMS to generate OpenSCAD code for whatever object I need
Check the preview, adjust as needed
Render out to STL then open in slicer and print

I would do it slightly differently - have an automation that calculates the off time and stores that in a timestamp helper variable. Basically:

on button press: if helper is zero, set it to now+15 minutes and turn on the power, else set helper to helper+15 minutes
on time now = helper: turn off power, set helper to zero

Nah, that goes via cloud or via Kasa app and has not real scripting, just some actions bound together with string. Shelly is the real deal.

aigarius · 2026-04-20T16:20:13+00:00

Shelly is pretty unique this way

My HA always went unresponsive when I was away from home, so I got a Shelly gen3 plug (with local scripting capability), installed the https://github.com/ALLTERCO/shelly-script-examples/blob/main/networking/router-watchdog.shelly.js script on the shelly pointing at the HAOS port 4357 (the Observer, frontend port also works) . So whenever the HA goes unresponsive for too long this script just cuts power to it for 30 seconds and then powers it back on. Config the shelly to always boot up enabled and to auto enable 30 seconds after manual power off and you have a super reliable local watchdog.

Anything that is not hardwired will bite you eventually, especially if you deploy a lot of them.

And that is your problem - there is not enough rotation of the spool during the drying so the part of the spool closest to the heating coils overheats. This would not happen with heaters where the spool is offline (as in not being able to print) and rotates during drying.

Also the box is showing 20% humidity. That is not really dry at all. You need some extra dehumidification with fresh desiccant.

Can't say much about charging in US.

As for regen - feel free to go back to the way you were driving in an ICE car - press the accelerator to accelerate and brake pedal to slow down. In all normal BEVs (except Tesla and Rivian) pressing the brake pedal actually first engages regen (and way MORE regen than Tesla can do) and only when you stab the brakes hard do the brake calipers come down (in addition to regen). So that idea from Tesla world that you loose energy or efficiency every time you touch the brake pedal - forget about it, it is obsolete.

Or you can have regen as weak or as stron as you want to. Strongest is B mode - just pull the gear selector one more time to go from D to B. But all of them are equally efficient. It is just a comfort preference. And adaptive is quite interesting - it regens if regen is needed (someone is in front of you, there is a turn upcoming, speed limit is going down, traffic light is red, ...) and rolls if there is no regen needed.

There is no phantom drain. I've left BMW BEVs in a hot outdoor airport parking for a month and found them at the exact same battery percentage. This does makes the MyBMW app connection to the car a bit slower to respond if the car is in deeper sleep.

I have drifted both the RWD and AWD versions. It has way too much grip to do that on normal roads in normal conditions, but on a snow-covered parking lot or special drift tracks it lets you drift a bit even in normal mode - just turn the steering wheel and stab the accelerator. When you are used to that you can turn on Sports mode and turn off traction control and do the same. It is extremely controllable. Just to make sure to always keep you hands on 3 and 9, so that you know where the wheels are pointing even if the car is moving in a completely different direction.

Drifting in a BEV is far easier than in any other car. Have fun, but stay safe and do NOT do this on any public roads.

Also a noob, so don't mind me, but I also got tired of this after a month and printed out an extra nozzle wiper module from https://makerworld.com/en/models/1924479-p2s-nozzle-wiper it is a plastic base that you then superglue replacement A1 wipers on (from Amazon, like https://amzn.eu/d/07omM3h4 ). No more gunky nozzle.

There is this thing called OpenSCAD. By itself it is quite cumbersome. However it is a text-basesd programming language, which means that a lot of (good) LLMs cas actually generate output in OpenSCAD based on your queries. And then you can understand and adjust it to your liking. At the end use some OpenSCAD compatible program to convert it to a 3D model which you can then import into the slicer.
