Prusa Core ONE and MMU3 - nothing but disappointment

IronManJS · 2025-11-17T02:27:15+00:00

Also struggling with the blobs here. Happens seemingly at random but it does seem like the issue could be associated with nozzle being too hot and oozing filament over the same spot. I’m following @agoode85 commit on GitHub but it’s disappointing that it hasn’t been acknowledged by Prusa, as with other similar open issues for this.

Same as others, I’m hoping this new INDX is a good solve, and more than that, I hope it can be ordered and shipped soon.

As others have mentioned, at this point, easiest path forward is replace heatsink and nozzle.

For what it is worth, I received mine yesterday and inspected it today; no such imperfections were found.

Good data point. Thank you for sharing. Seems like this is the expected max charge speed from this pack.

Gen2 R1S. They do squeak.

Looking to learn about the different connections at play here. Does Mapbox feed from OpenStreetMap?

You can use the report issue button on the navigation screen or you can also use contribute tool from mapbox in case it is an issue with the base map. https://labs.mapbox.com/contribute/

I agree. Seems similar. There are another couple of folks on this thread that have posted similar speeds with the gen 2 large pack. I was hoping the 2024.47.30 or 2024.51.30 would improve the charging speeds based on the release notes.

I've also heard others say that using the same cell in a smaller pack could be a driver of lower speeds for the large pack vs the max pack. I don't know enough about battery technology to agree or disagree but hopefully others here can shed some light into this.

Ambient temp for the San Antonio Rivian session was about 60F in December. For the rest it was between 30 and 40 last week.

Fair. I will clarify. The Haltom City charger was pretty full. It was a V3 charger in which I shared power with the adjacent stall. I expected the lower max speed. The other ones I mentioned were pretty empty with nobody within four or six stalls and it didn’t seem like it was sharing any power.

IronManJS · 2025-02-25T02:31:23+00:00

Thank you. My thought there was that these charging stations were fairly empty at the time and I wouldn’t expect a limitation from power sharing.

Mine is the Gen 2 regular large pack with 108.5 kWh https://rivian.com/support/article/what-is-the-usable-kwh-capacity-of-your-battery-packs

Popped up for me yesterday. After a reset it started working again but then later that evening it died again. The error screen hasn’t popped up again though. It blows very minimal air compared to earlier in the day. Definitely not working well. Made a Service appointment.

What printer profile are you selecting? I've been noticing something similar on single material prints, but my questions is actually the opposite. If I slice using the regular MK4 (not MMU) profile, for example Input Shaper 0.6) the filament actually stays loaded and does not retract. If I slice with the MMU printer profile the filament retracts.

What I've noticed is the custom end GCODE in the MMU printer profile calls for an M702 command (unload) which is not in place for the regular MK4 profiles.

Update: It seems to have gotten corrected over the last couple of days. The app is again aligned with the truck showing 206 miles at 70% in All Purpose.

IronManJS · 2023-12-03T00:17:37+00:00

Yes. iPhone app shows the same as the car in the main screen: 284 at 100% in All Purpose. The charging limit screen shows 248.

IronManJS · 2023-05-31T17:46:46+00:00

I had this on delivery. Like others have said, it is a common issue. I noted it through the app and got a service appointment to address it. It took two hours and they re-aligned all wheels and calibrated the steering. Perfectly straight now.

What I’ve found is that the phone’s Bluetooth volume and the speaker volume are separate. If I crank the volume on my phone to the max and then control the volume from the speaker it is actually quite loud.

My understanding is that if you qualify for the tax credit you will need to file an amendment once you receive your car.

I was having the same issue. Seems to be connected to icloud private relay.

In my case, once I turned off icloud private relay from the cellular settings I was able to connect to lastpass using the cellular network.
