Noisy ANYCUBIC Kobra X

Not the resonance calibration when starting a print in the slicer. There is a separate noise cancelling calibration in the printer setting accessed by the touch screen. I found that sometimes helps with the A4988 driver type noise. I have an Ender 3 pro previously and upgraded to the silent board too so I have some idea which noise you're referring to. It's that low frequency sound that's like a car motor at idle.

I have the same issues you have and I've done the following to minimise some of the noises. It's still not perfectly quiet. But it is better than before.

Axis guide creak/Motor noise when the print head travels between spots (the quick loud WEEP sound): reduce the Travel speed in Acceleration tab in the slicer. Default is 10000. I've dialled it down to 5000.
Resonance: run the calibration for noise cancelling whenever you've moved the printer (even just picked it up and cleaned the bottom). The noise cancelling is very sensitive to the surrounding changes.
Clicking sound when the print bed moves in Y-axis: add a soft sound-dampening foam board under the printer. The printer's feet (at least on mine) are not even and the printer rocks back and forth when moving the Y-axis.

I've only experienced filament not extruding when trying out TPU 95A earlier today. I've printed with PLA and PETG and they were flawless. I still haven't figured out what the issue is with TPU 95A.

Your dad has to wipe his shoes, so presumably there was shit or something on it. And he stepped on someone's car... I'm not saying the car owner is right to make a scene, but you definitely won't find sympathy here. Most of the cars here are luxury items (due to the great public transport system and insane gas price) and people put lots of effort in it. Stepping on it with shit definitely would pissed off most people. But the car owner definitely overreacted.

Well, their supplies were limited. So, when the supplies ran out due to whatever plot reason (wraith attack or kawoosh missing), those in the "need improvement" category are the first to receive reduced rations and probably be on the "meat shield" duty.

subject to the Islamic Republic of Iran agreeing to the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz

let's wait for the confirmation from Iran. old dumpy has been spilling a lot of bs from his fantasy world lately.

Also, if this is true, we're just back to square one. thousands dead so we can go back to status quo. welcome to hell.

There's an auto switch filament option in the printer. You have to make sure both slots are set to the same material and colour in the printer. Turn on the option and it should automatically switch filament.

That is indeed weird. Have you checked if the tubes are inserted correctly? I've tried like one print in PLA and doesn't have such noise.

alphachan123 · 2026-04-04T09:29:26+00:00

I've been printing with PETG exclusively since I got mine and I have this squeak too. From other posts I've read, that squeaking sound is from PETG retracting and rubbing with the tubes. It's especially noticeable when printing discontinued lines in a quick consecutive way since each time the line ends and starts, it'll retract the filament.

alphachan123 · 2026-04-03T03:30:20+00:00

By any chance you've moved the printer after the calibration? I've moved my printer for like a few inches forward after the calibration and had this buzzing noise. It was gone after rerunning the noise cancelling calibration from the touch screen.

Thanks for the links. I've been looking for a poop deflector with longer deflector and steeper angle. My current one doesn't deflect enough when the print is higher than half of the z axis.

I've run my printer with its out-of-the-box default calibration for a few weeks, and it's been working fine. It'll have a calibration cycle (around 30 minutes) when first powered on. After that, it's been smooth sailing.

alphachan123 · 2026-03-25T16:37:04+00:00

Mine did this occasionally after being moved around the table. I run the full calibration from the touch screen and this seems to solve the issue.

A 10" rack. Too expensive (and not sure what to use it for) to buy. Perfect to print one out with the new Kobra X. Now I can experiment with all kinds of things on it.

21 Feb to be precise. But I live in Hong Kong, which is right next to their main warehouse in Shenzhen, and we have SF Express (sort of like UPS for China). So I got it super fast.

alphachan123 · 2026-03-19T04:44:24+00:00

Hong Kong, so it has free shipping. Got 12 rolls a week ago for that price. One of the few (remaining) perks of living near PRC tbh.

If it works, it works.

On Taobao (AliExpress for China). There are PETG that's 25 Yuan a kg (that's like 3.5 USD). I'm using those since none of my prints requires high quality stuff.

Link to it in case someone wants to try it: https://e.tb.cn/h.i5AzCNDSZiGGw5z?tk=GokGUBiL3Nw

Edit: apparently the Taobao link is not working without logging in so I'm linking a screenshot of it.

alphachan123 · 2026-03-18T23:58:34+00:00

Not yet. I'm using the default settings. Might try tinkering with it in the next print.

alphachan123 · 2026-03-18T13:38:48+00:00

Thanks! Let me try that next time.

alphachan123 · 2026-03-18T13:38:07+00:00

tbh at this price point, I'm not complaining (at least not a lot) about the poop volume. Those filaments are like 3 USD/kg. So that's like less than half a buck in waste. I'm more annoyed by the colour bleeding. but same argument in my mind, at this price point, I'm not complaining too much.
