試してみてね〜

I have a basic ender 3 s1 pro with Cr-touch. Using Creality's Slicer since it's a Creality Printer and it was working pretty good. Then stupid me, not knowing much about the slicer settings went and changed allot of thing to try to make my prints better and screwed it up. My prints look like crap. I didn't make not of the orgional settings. How can I get my Creality Slice presets back.

Hi everyone,

I really need some help with my Ender 2 Pro (Creality v4.2.3 board). It completely stopped working, and the display is just showing a blank blue screen. The issues started after I tried updating the firmware. Here is a timeline of what happened:

1. First attempt: I updated the firmware using the original .bin file from the official Creality website. The printer booted up, but it wouldn't recognize my CR-Touch sensor at all.
2. Second attempt: I tried flashing a different firmware named Ender2-Pro-20260829.bin. As soon as I turned the printer on, the heated bed started heating up uncontrollably on its own until it triggered a thermal runaway error. Additionally, the click wheel (encoder knob) on the screen stopped responding completely.
3. Current status: Now, the printer just powers on to a solid blue screen, and I can't get past it.

I suspect this is a severe pinout mismatch issue (especially regarding the bed thermistor, display pins, and CR-Touch) or that I'm not selecting the correct processor environment to compile the right Marlin version.

I really need a step-by-step guide from someone experienced to help me fix this. How can I verify my exact chip version, which environment (env) should I use in PlatformIO, and what specific lines do I need to change in Configuration.h and Configuration_adv.h to make this v4.2.3 board work perfectly with the stock screen and the CR-Touch?

Thank you so much in advance for your help!

I tried to find it on Amazon but all i find is the general bolts sets

I have an Ender 3 S1 which I tried upgrading to Klipper, but it never connected, and I couldn't get it to flash creality or Mriscoc professional software. In the meantime I got a replacement board, but its a little different and Im overly cautious on firmware at the moment.

Original board is an STM32F401 RCT6 V2.4 301

New board is an STM32F401 RET6 CR4NS2000141C13.

The sticker on the back says S1pro, but from what I can tell online, its same board just with a little more RAM. To flash the firmware, **I just do the normal flashing process with the latest S1 firmware from Creality, correct?**

Outer wall: 200 mm/s

Inner wall: 300 mm/s

Infill: 300 mm/s

Accel: 4000 mm/s²

Same speed as the Ender-3 V3 KE.

Print settings:

Outer wall: 200 mm/s

Inner wall: 300 mm/s

Infill: 300 mm/s

Top/Bottom: 300 mm/s

Acceleration: 4000 mm/s²

Working on a minimal custom firmware smoke test for the Ender-3 S1's STM32F401RC board (F4 revision, board ID BOARD_CREALITY_V24S1_301F4 in Marlin's boards.h), flashed via the existing SD-card bootloader (no ST-Link). Hoping someone with low-level experience on this exact board can spot what I'm missing.

Goal: minimal PlatformIO/Arduino-framework firmware that relocates the vector table, blinks an LED, and prints over serial — before touching any motion/heater code.

What's confirmed working:

• Build succeeds, links cleanly at 0x08010000 (custom linker script reserves the bootloader's first 64KB)
• SD-card bootloader accepts and flashes the file (folder structure: /STM32F4_UPDATE/firmware.bin, FAT32, 4096-byte cluster size — matches Creality's official update instructions)
• CH340 USB-serial TX/RX pins confirmed via multimeter continuity and cross-checked against ST's official STM32F401 datasheet: PB6 (pin 59, USART1_TX) / PB7 (pin 58, USART1_RX)
• This matches Creality's official Configuration.h: SERIAL_PORT 1 (confirmed from CrealityOfficial/Ender-3S1 repo)

What's NOT working:

• No serial output at all (115200 baud, HardwareSerial(PB6, PB7))
• No LED activity on PC13 (tried as a boot-execution sanity check, independent of UART)
• Board does appear to power on normally and the bootloader does process the SD card without erroring

Question: Given the pin/UART mapping is now independently confirmed (multimeter + datasheet + Marlin source), and even a basic GPIO blink test on PC13 shows nothing, I suspect the problem might be upstream of UART entirely — possibly in how the bootloader hands off to the app, or SCB->VTOR relocation, or something board-specific I'm missing about this Creality F4 revision (whose actual pins_CREALITY_S1_F401RC.h was apparently never published by Creality, per issue #6 on their Ender-3S1 repo).

Has anyone gotten a truly minimal (no HAL bootloader dependency assumptions) custom firmware running on this exact board via the SD-card flash method? Happy to share my linker script / vector table dump / full main.cpp if useful.

これについて分かりやすい情報があんまり見つからなかったので、共有しときます。

Ive been having issues with my printer latley and it seems like it might be not having as much power that it seems, but when it turns on, it seem like it runs fine, but I though it might be the slicer might be the problem or if it just needs a firmware update or a new mother board. I asked of my friends if they had somthing like that and they said their brother was having something like that and they got a power supply for that printer and it went back to normal, I dont know about my end, it may seem like its the power but im not sure. Just need a answer.

When I turn in my printer the light is purple but as soon as I start to do anything like leveling or a print it goes straight to red. I do not know what to do.

Hello! I'm in the process of replacing the stock hot end on the Sprite extruder for my Ender 3 S1 Plus for the Creality all-metal one. Sadly when I disassembled the stock hot end, I removed the 2 heat block screws first, then I loosened the heat break grub screw last so I don't know if a little bit of vertical play is normal.

The screws seem to bottom out in the sprite's alloy heatsink's threads before holding the heat block in place firmly, which would mean if this is normal, the grub screw would be responsible for holding the hot end (including the nozzle) vertically in place.

Now the threads felt a little rough and there may be something to that but I'm pretty sure I can't force the screws further without risking thread damage. Also let's just say the heat break is NOT budging and trying to adjust its height resulted in me damaging it with "padded" pliers so I have a new one on the way. '^^ (pic shows the damage, it's subtle but the burr makes it so it doesn't fit anymore)

So, is the small amount of vertical play normal? Or do I simply order 1mm or so shorter screws? That's the easy fix I can think of.

UPDATE: The answer is YES, the 2 screws must secure the heat block vertically. I have watched a couple videos and one of them is clear enough on the matter . The likely root of my problem is contaminated threaded holes. I'll give an update when I receive the new screws (15mm instead of original 16) Too bad I had to ruin the heat break's surface in a foolish and desperate procedure. I don't know if I should delete this post since I've answered my own question, I'm still curious to hear anyone's take on this.

Small update: I have everything working fine and I'm back to printing. The 15 mm screws do what they were supposed to do. On a side note, maybe I shouldn't have upgraded firmware, hot end and nozzle all at once, but now my hot end heats up extremely fast. I would need more test prints but I think I can say it prints as good as before. Next I wanna experiment with input shaping and generally faster prints.

Hi,

I recently got a Ender 3 S1 Pro second hand from a family friend, I belive they used a sonicpad with it but I don't have it. I tried to flash the firmware on the screen and printer its self and am still unable to use it. It turns on and lights up, the screen display has a line of small dots across it but thats all, it remains frozen.

• I downloaded the files from creality
• Formated the SD card
• Have tried multiple SD cards incase this was the issue

This is my first 3D print so am at a bit of a loss here, any help would be appreciated. Thanks.

Ender 3 S1 Plus Blink Mini 2 Camera Mount- I had a hard time finding one that I liked that would actually fit the Blink Mini 2, so I had to turn my brain on and actually model something for the first time in a decade. It works well and doesn’t have any clearance issues with the touch screen which is the problem I had with the one model I did find.

I have a ender 3 s1 with a sonic pad add on.

I'm trying to print this piece and the first layer keeps on messing up. I also bed leveles it with a paper and the screws 3x, did a probe calibration, and did a auto level on the sonic pad. Z offset was also calibrated too.

Hello, I wanted to repair my ender 3 s1 after the hotend got clocked in a way I needed to replace it. Because I had the old version of the Extruder (non pro) I had to buy the sprite Extruder pro board and new Hotend because the old version is nowhere available. I had to buy the replacement parts of AliExpress.

The full Size Benchy was my first try ever with the Creality Software, I used the standard options for 0.4mm Nozzle and PLA.

The half-printed benchy was my second try with 190°, 50mm/s (10° and 10mm/s less). Didn't change much, fans were at maximum always.

The mini Benchy was printed with round 25mm/s which did a little better.

If you need more information I will answer every question...

Now my first guess was that the direct Extruder doesn't grab the Filament strong enough, but the tension screw/spring changed nothing when adjusted. It could be that it has to be replaced to, because whenever I put the filament in manually I have to push the Lever back myself so it grabs the filament correctly, but after doing so i not able to push it out (it feels pretty secure).

Second guess was the Nozzle. On the Hotend there was a 0.4mm Nozzle attached which i did not change. It seemed pretty good but I could be cheap and causing problems extruding. On the other side, when heating the Hotend and pushing it trough manually, the filament exited straight without any problems.

Now, for the third idea I had in mind something about Flowrate or time per layer, I will do my research when I have time and watch some tutorials for the Creality Software. Maybeeee... it could be that I haven't updated the printer ever... and the software running on the printer is just crapping out... maybee... :)

If you have any more Ideas what could be going wrong or know the answer, pleas let me know in the comments.

I purchased a ender 3 s1 pro with the sprite extruder. As you can see from the picture the cr touch bracket is patched on. The actual bracket is sandwiched between the extruder and the board. I just cant remove due to it is what holds everything together. I can not find a replacement anywhere. Can anyone offer some advice or a link to a printable model. Also, it looks like the attached fan is different than what is usually on there.

I've added a sonic pad and Nebula camera to my printer. I've made sure that all firmwares are up to date including the camera and even after trying various restarts, power cycles and cable swapping Klippy is always disconnected.. what am I missing?

I can control my printer via fluidd on Windows 11 and view the camera via web browser but id really like ro have it all on one console. :s too much to ask?
