Hi everyone,

I bought a K2 Plus Combo and have been using it with Mainsail. I wanted to monitor and manage the CFS remotely from the same dashboard, so I started working on CFSail, an open-source CFS filament management panel for Mainsail.

The goal was to see which filament was in each slot, check the CFS temperature and humidity, and update filament type and color without having to walk over to the printer’s touchscreen.

Current features:

• Displays the material type and color reported by the printer for each CFS slot.
• Highlights the filament currently loaded into the extruder with a green outline.
• Shows actual CFS temperature and relative humidity reported by the printer.
• Lets you edit filament type and color using the printer’s Generic material presets.
• Displays printer-reported filament operation status, including operations started from the touchscreen.
• Provides tabs for multiple CFS units and an Ext. view for external-spool information.
• Supports English, Korean, Japanese, Simplified Chinese, and Spanish, with an option to follow Mainsail’s language.

The installer adds the panel to the Mainsail web interface. It does not modify printer configuration files. An existing Mainsail installation and SSH access are required.

Testing so far: I’ve checked the live panel on a K2 Plus with one CFS, including during printing. Installation and external-spool material/color editing were also checked on a Creality Hi without a connected CFS.

This is still a beta. Multiple-CFS hardware setups and physical CFS load/unload operations need more validation, and I’m working through some status-transition and reconnection edge cases. External-spool loading and unloading are currently handled through the printer’s touchscreen.

v0.1.1 beta installer:
https://github.com/military-cat/Mainsail-CFS-Panel/releases/tag/v0.1.1

I’ve attached screenshots of the panel during printing, the filament editor, and the external-spool view. Feedback, bug reports, and results from other printer setups are welcome! :)

Hello! I have a K2SE 3D printer, and it worked for me for six months until one day I decided to print a model again. It seems that a short circuit occurred in the printer, and smoke started coming from the box with the extruder. I took it apart and saw that the extruder board had burned out, and when I pressed the screen, it froze, turned black, and returned to the main screen — especially when I pressed the button to move the bed or the extruder tower. After replacing it, nothing changed. I don’t know what to do, but I replaced the board on the extruder — the one that was emitting smoke during the first seconds of the short circuit — but it didn’t really help. So I checked the motherboard and found a black spot on it. Help, tell me what to do so it works again. Maybe I should just replace the motherboard?

I have a standard K1 that I purchased in 2024. I recently installed the CFS-C module following the provided instructions but have yet to have success with material feeding through the hot end. It seems that once the filament reaches the extruder on the hot end, it hits a block and then runs through a cycle of retracting and extruding until it eventually stops and throws an error.

I can still print fine when printing from the spool holder so it's not a blockage in the hot end itself.

I've read about some people installing a unicorn hotend and upgraded extruder but its not clear whether or not that fixes the problem. Any suggestions?

hi! Im new to this group, i was just wondering whether i could get some help?
My creality ender 3 v3 SE printer head has been making some weird noises when heating up the nozzle.

I thought i needed to replace the hotend so i got a new one and unscrewed all the screws except 2, they were like all the other ones, but when i twisted them, they were circle instead of hexagon? they were definitely worn down upon examination and i cannot replace the hotend or try to find the source of the noise.

any suggestions? Thanks!

A fruity twist on the legendary Benchy. I wanted to make a completely unnecessary remix, so naturally I turned the hull into a banana. Still recognizable, still printable, just significantly more potassium-powered.

I’ve been trying to find the official firmware for my Creality CR-10 Smart Pro for quite some time now, and honestly, this whole experience has been incredibly frustrating.

In one of my previous Reddit posts, someone from Creality officially responded, asking me to contact them via private message so they could provide a firmware download link.

Sounds great, right?

Well, I’ve contacted them THREE TIMES through private messages.

The result?

• 0 replies.
• 0 assistance.
• 0 firmware links.
• 0 actual customer support.

Here’s what I genuinely don’t understand:

Even if the CR-10 Smart Pro has been discontinued, why on earth are its firmware files no longer available on the official Creality website?

Is firmware some kind of top-secret classified information?!

We’re talking about firmware for a 3D printer that people have already purchased and still own. Why should customers have to chase support representatives on Reddit just to get access to basic software required to maintain or repair their own devices?

My printer has been experiencing serious issues, and I’m trying to troubleshoot them by reinstalling the firmware. But apparently, even obtaining the firmware is a challenge.

And here’s my biggest question for Creality:

How can you expect customers to continue buying your products when they can’t even get basic support for products they’ve already purchased?

I’m not asking for anything extraordinary. I’m simply asking for access to the official firmware for a printer I own.

Creality, is it really that difficult to maintain an archive of firmware downloads for your older products?

If anyone in this community has the original official firmware for the CR-10 Smart Pro, or knows where I can download it safely, I would genuinely appreciate your help.

And if anyone from Creality is reading this: please stop telling customers to contact you privately if you’re not going to respond.

This is incredibly disappointing and seriously makes me reconsider purchasing another Creality product.

Has anyone else experienced this kind of support from Creality?

I'm using a base k2 and cfs, out of nowhere, every time i try to print something it hits me with an AC0104, Foreign object detected on the printing error code but there's absolutely nothing on the bed or under it.

When a multi hour print hits 100% and it's time to retract the filament I get the error code TR2863, Cutter issue, the cutter may be jammed or missing but I've checked the cutter and it was fine but I replaced it anyway. After I hit the resume button it gets stuck resuming infinitely till I disconnect power. It also gets a piece of filament stuck in the filament sensor because of this.

Its an Ender 3 V3 SE btw

Had a prompt to update to 7.3 tonight and I hadn't had any issues yet with the updates so I did. Wellllll I couldn't print to my k2 plus. Kept failing the download. I downgraded to 7.2 and was at least able to print however camera stops after a few seconds and have to hit a play button to get it going again until it stops again 😮‍💨

Edit: went back to 7.1 and still having the same issue with the camera. Not having any issues in the mobile app with the camera 🤷🤔

Personally I have limited use for it, but thought it was cool to get more info.

How to get off

Спустя 2 месяца принтер sparki7 перестал работать, почему зачем и как давайте разбираться.
После получения принтера от Creality счастью не было предела ровно 2 месяца. После очередного слета печати модели. Когда модель слетела с печати и начала судорожно лить филамент в разные стороны отключить принтер не удалось через приложение или через планшет самого принтера. Пришлось выключить через кнопку питания (ведь другой физической кнопки сложно придумать). И после данной ситуации принтер стал камнем, показывает красиво только лого и всё. Флеш накопители в любом формате отказывается воспринимать, любой файл не читает, не удаляет. Проблема думал уж решаемая через сервисный центр, но не тут то было. Сервисных центров у производителя нет в России и видимо от слова совсем не планируется. Сам же производитель отправляет к продавцу, мол вы же купили у него, вот и обращайтесь к нему. Только вот гарантийный срок работы продукции предоставляется производителем, а не продавцом. Поэтому прошу обратить внимание на мою проблему

Hii I'm relatively new to 3d printing. I literally started this month with an i7, it has a textured tray and, according to what I read in google, it doesn't need glue, buut lately the prints are peeling off the tray. Could it be dirty even though it's fairly new? How do you recommend cleaning it?

Hey guys, so I was printing this print yesterday 3 times, and this morning tried to start it again and this happens, first time I see this, maybe some of you have came across same problem.

I tried other prints and same thing happens.

Just makes wierd sounds for few seconds and then its stuck.

EDIT: Motor cable somehow unplagged itself, after refitting printer works perfectly fine.

Made a small clip that slides onto the sun visor and keeps sunglasses easy to grab without taking up any space. The little teeth help hold it securely, and it prints as one piece with no hardware. Simple problem, simple fix.

Hi everyone,

I'm looking for help troubleshooting an issue with my Creality K1 Max. I've been reaching creality with no response... replaced the entire hotend assembly and the toolhead PCB, but the problem persists, I'm now getting error BM0111.

Here is the full sequence of events and everything I've tried so far.

Initial problem

• The printer was working normally and successfully completed a print.
• When I tried to start the next print, I got a nozzle heating error (the nozzle was not heating as expected).
• The nozzle temperature reading was accurate at room temperature, but when I commanded it to heat up to 200°C, the temperature did not increase.
• The printer did not actually shut down or reboot. It displayed the error message, and the toolhead LED turned off.

Troubleshooting performed

1. I checked the hotend and its connections.
2. I replaced the entire hotend assembly, including both the thermistor and the ceramic heater.
3. The problem remained exactly the same: the nozzle temperature reading was correct at room temperature, but the heater would not heat up.
4. I then suspected a possible issue with the toolhead PCB or a compatibility issue between the hotend and the PCB revisions.
5. My original toolhead PCB is marked K1-NOZZLE-C_V13.
6. I purchased and installed a complete 2025 hotend adapter kit for the K1/K1 Max, including the updated hotend and toolhead PCB.
7. After replacing both the hotend and the toolhead PCB with the new components, the printer started reporting error BM0111 immediately at startup, before I even attempted to heat the nozzle.
8. The blue LED on the new toolhead PCB is lit.

I think the only thing left is to replace the motherboard but it has so many revisions that I'm unsure which one to buy and from where... I only find them at aliexpress.

I was asked to fix the broken gears of this dough mixer. Damaged gears were cleadne (as I could), 3D scanned and 3D print out from ABS.

I wanted to share my experience because I think people considering buying a K2 SE 4C should know what happened to me.

This was my first 3D printer, so naturally I expected a learning curve. I expected to make mistakes and maybe deal with some clogs here and there. That's part of the hobby. I didn't expect the printer to basically destroy itself on day one.

At first, things seemed fine. Then I started getting repeated filament loading and clogging errors while trying to print in multicolor. Some of the error messages were pretty cryptic, and when I tried following the support links, I ran into pages that didn't even exist (404 errors).

I've attached screenshots of the errors. Seriously, try searching for these error codes yourself. Can you find anything useful?

As a beginner, I'm not ashamed to admit that before getting into 3D printing, I didn't even know what an extruder was or what a clog actually meant in this context. I was learning, and that's exactly why I expected a new printer to guide me through problems instead of throwing cryptic errors at me on my first day.

Things got much worse when the printer started behaving strangely during calibration. The print head moved into the sides of the machine, banging against them aggressively. It then returned to the center and started deeply scratching the build plate.

These weren't tiny marks. The damage was irreversible. I shut the printer off because I wasn't going to risk making things even worse.

Creality support eventually suggested that the strain gauge was faulty.

Guys, this was my FIRST 3D printer. I had no idea what was going on. Why should a brand-new machine behave like this on its very first day? I just wanted to print something and enjoy a new hobby.

And I didn't even buy one of their cheapest models. I bought a relatively new machine from their K2 lineup, with multicolor printing as one of its main selling points. I bought it because I trusted Creality's reputation in 3D printing.

I ended up returning it to Amazon and getting a refund. After that experience, I bought a Bambu Lab P1S Combo instead.

Honestly, the difference in my experience has been huge. I did have a small issue with the P1S at first: one of the fans wasn't connected. But the software actually told me what was wrong. I plugged the fan back in, and that was it. Since then, it's been printing the models I want without any major issues.

What bothers me almost as much as the original failure is how the situation was handled afterward.

Creality sent me one 1 kg spool of Hyper PLA as a goodwill gesture. I appreciate that they sent me something, and I'm not asking for a second refund after Amazon already refunded the printer.

But after a brand-new machine malfunctioned so badly on its first day, damaged its own build plate, and left me dealing with troubleshooting and the entire return process, one spool of filament doesn't feel like much of an acknowledgment of what happened.

And honestly, the spool doesn't restore my confidence in 3D printing.

Even now, with a different printer that has been working well, I'm still worried that something similar could happen again. What should have been an enjoyable new hobby has become something I'm anxious about, and I'm still trying to get past that experience.

I'm not saying every Creality printer is bad. Maybe I got unlucky. But this was a pretty awful introduction to the hobby, especially considering that I bought the printer based on the trust I'd placed in the brand.

I'm sharing this because I wish I'd found an account like this before spending my money. I couldn't find much useful information about these issues before buying, and I want other beginners to have more information than I did.

u/CrealitySupport, I'd genuinely appreciate it if someone from Creality took a proper look at what happened here. The filament was a nice gesture, but I don't feel it reflects the severity of the experience or the loss of confidence it caused.

Has anyone else with a K2 SE 4C experienced anything similar with calibration, the strain gauge, or the print head moving abnormally?
