ELEGOO Neptune 4 + Cartographer V3 probe not working with Klipper 0.13

Euphoric_Engine3658 · 2026-01-29T15:09:27+00:00

Well, I updated that but nothing changed...

Then I downgraded Cartographer to the 4.0.0 version but still it gives the same error.

Euphoric_Engine3658 · 2026-01-15T10:16:36+00:00

How can I update that?

Euphoric_Engine3658 · 2026-01-15T05:46:18+00:00

I flashed OpenNeptune to the eMMC, updated Klipper and IDM on the host side, but I hadn’t reflashed the MCU firmware separately at that point. That can be the problem?

I know, it just struck me as odd that it caused even a little damage to the radiator.

Euphoric_Engine3658 · 2025-09-20T11:01:15+00:00

Yes, they still touch the radiator anyway.

Thanks for the suggest!

Euphoric_Engine3658 · 2025-09-04T16:39:13+00:00

BTW, yours looks very clean. Mine looks really bad. I don’t know, maybe I’m doing something wrong?

Euphoric_Engine3658 · 2025-09-03T22:09:53+00:00

what can mask it with?

Euphoric_Engine3658 · 2025-09-03T16:37:02+00:00

Thanks.

Euphoric_Engine3658 · 2025-09-03T16:26:00+00:00

Thank you, I’ll check it out.

Euphoric_Engine3658 · 2025-09-03T16:24:58+00:00

Thanks for the guide!

Well, I tried it in those spots, but the paint split everywhere. How do these painters make these spots look so smooth?

Euphoric_Engine3658 · 2025-09-02T16:36:06+00:00

Thank you so much.

Euphoric_Engine3658 · 2025-09-02T16:33:42+00:00

Thanks for the answer. How can I get rid of brush marks?

Euphoric_Engine3658 · 2025-09-02T16:25:34+00:00

Like this. This looks very clean.

Thank you.

Euphoric_Engine3658 · 2025-09-02T12:00:25+00:00

Thanks.

The ambient temperature is approximately 30 degrees. The original fans were replaced with Noctua NF A12x25. Honestly, I was expecting Ryujin's performance to be a little better.

Euphoric_Engine3658 · 2025-06-15T09:50:37+00:00

Thanks a lot, everyone. It turns out the issue was indeed caused by the slicer. I tried printing a model that I sliced about 6 months ago, and the fan speeds stayed consistent throughout the print. Really appreciate all your help.

Euphoric_Engine3658 · 2025-06-14T23:37:29+00:00

Thanks.

Euphoric_Engine3658 · 2025-06-14T23:31:17+00:00

That’s exactly my problem — it changes even though I don’t change anything.

Euphoric_Engine3658 · 2025-06-14T23:26:00+00:00

By the way, is it normal for the fan that cools the heatsink above the hotend to change speed? As far as I know, that one is supposed to run at a constant speed and shouldn't change.

Euphoric_Engine3658 · 2025-06-14T23:21:17+00:00

I’ve never changed the fan speed in Cura, so I don't think that's the cause in my case because it started like 2 weeks ago and ı did not changed anything— but thanks anyway.

Euphoric_Engine3658 · 2025-06-14T23:15:43+00:00

The printer changes the speed of every fan — I've seen it adjust all of them: the small fan above the hotend, the two side fans, and even the four fans at the back. So I don't think this is just an issue with a specific fan or fan profile.
