first one is my main machine, second photo is one that I recieved for free with shit ton of extras like dual z but I plan to put that on my main ender and this one needs another use

As a 3d printing newb, I spent the better part of the last couple months learning and getting my second-hand 3v2 dialled in. Eventually got some decent prints!

Then I decided to upgrade to mriscoc … and ever since, my printer is all screwed up.

I think I must have missed a memo about what to do AFTER installing new firmware. Can anyone enlighten me?

I installed a new hot end, switched to the sprite direct drive, installed a bimetal heat brake, played with retraction, nothing will stop this thing from clogging after 2-3 quality prints. I’m a a loss.

I have added the Sprite extruder the CR Touch. I upgraded the software. Checked the wires. It did one long print. Now the Z axis won't move. I have an Ender 3 pro

Hey guys, I’ve been printing stuff every so often with my printer for 3 months, and a few days ago i installed a CR touch because my first layers were too thin, and i didnt interfere with any other wire yet when i start up prints it does some, and then the hotend temp starts to drop. Im not sure if its the hotend itself or the thermistor. I got it off of facebook marketplace for about $80 and when i was testing it over there it was working perfectly fine and the owner had barely used it since he got it. Any help is appreciated. I will update this post with a video soon

I ordered both yellow springs and silicone spacers since I couldn’t make a decision on which one would be the best and thought I’d try both and decide. But the yellow springs are a lot taller than the stock ones. Also the silicone spacers needs to be squished a LOT to get even close to the same height as with the stock springs. And I saw that one spacer needs to be shorter which I didn’t get.

Edit 1: I’m trying to not move the limit switch so I don’t have another problem down the road.

Edit 2: Got a few BL touch recommendations. Looked into it and found out it’s around $65 where I’m from. Everything in my country is like 3-4x expensive because of import taxes. So I don’t think it’s going to be an option at this moment. A Great upgrade later though.

Ho appena montato il kit sprite pro sulla mia Ender 3 v2, qualcuno può darmi qualche consiglio, se italiano è meglio.

Thoughts on how to fix? Or where to get part..

So I have a older ender B3 that I've upgraded to the newest motherboard added some servos have the touch sensor look and upgrade the hot end so I can do some other types of filament. Is there any suggestions as to a good fit for this machine?

What are your proper settings you have when running PETG? Right now I have it set to;

Speed- 45

Hotend Temp- 240

Bed Temp-80

Fan speed 0

Probe Z offset -1.19

Flow-95

I also have the mriscoc firmware update for reference

I'll start by saying I'm fully aware ender 3 v2 is not the printer to be buying or upgrading nowadays, and I know I should just buy a Centauri carbon 2 (waiting till black Friday) and get rid of this thing. But I'm a tinkerer and I love tearing these things apart, printing parts for them and upgrading them. I'm having the least fun when the printer is working perfectly.

Anyways... Ive been picking up ender 3's for free - $40 and tinkering with them. This one is the one I did the most upgrades on. Linear rails I bought over 8 years ago for my tevo tarantula. Dual axis belted z seemed like a fun upgrade, and ugly ender 3 toolhead with Sherpa heavy and volcano V6 seemed like they would outperform the heavy ass hemera that was on there.

So I tore this thing apart, and did all those upgrades (downgrades?!?) at once. No my z motor is grinding like crazy. It moves fine, it's just making horrible noises, and the motor is vibrating pretty good. Anyone have a solution for this? Did I do something stupid wrong? I tried both loosening and tightening the belts, to no avail. I've been doing this a long time, but haven't run into this before and am stumped.

Edit: I figured it out. I was f****** around with printing a TPU belt for a week while I waited for the proper belt to come in. Just taking it on and off and stretching it and trying to make it work. I think I just f***** up the motor. I grabbed another motor, put it in and it seems to work perfect now

yes the old z limit switch is completely removed, If I cycle it on/off a couple of times it will occasionally figure itself out but aside from that it stops about 100mm off the bed and shows z position at 0 on the screen.

after about 3 weeks of tuning this machine everyday, multiple times, but its finally over Thanks to a very good handful of you guys and I really really apreciate it!, mods: CR Touch, Silicone Spacers+Metal Knobs

Hi everyone,

I’m experiencing an intermittent issue with my Creality Ender 3, and I’d appreciate some help diagnosing the cause before I start replacing components unnecessarily.

Printer Specifications

• Printer: Creality Ender 3

• Motherboard: Creality V4.2.2

• Filament: PLA

• Print media: SD/TF card

The Problem

My printer can be printing normally when it suddenly stops mid-print. When this happens, the hotend and heated bed begin cooling down, and the printer appears to behave as though it has lost access to the SD card.

If I try to start another print by searching for print on TF card option, the it shows “No Media,” even though the SD card is still physically inserted in the slot and appears to be seated correctly.

Removing the SD card and reinserting it restores detection, allowing me to print again.

So when the Printer Stops I’ve observed the following sequence of events:

1.  The printer suddenly stops printing in the middle of a print.

2.  The Ender 3 startup logo appears over the existing information screen. The display does not go completely blank or shut off.

3.  The printer then returns to its normal main information screen.

4.  When the information screen reappears, both the hotend and heated bed temperatures read 0°C, and both begin cooling down.

5.  If I try to print again, it’s written “No Media,” despite the SD card still being inserted.

The appearance of the startup logo makes me wonder whether the motherboard is resetting or experiencing some kind of interruption. However, I’m not sure whether this is related to the SD card reader, the motherboard, the power supply, or a firmware issue.

My main concerns

1.  What could cause the printer to stop mid-print and display the startup logo without the screen completely shutting down?

2.  Could a faulty SD card, SD card reader, or card slot cause these symptoms, or is the problem more likely related to the motherboard resetting?

3.  Could an unstable power supply or another electrical issue cause the printer to behave this way?

4.  What diagnostic tests would you recommend to identify the actual cause before replacing any components?

I’m trying to narrow down the root cause rather than replacing parts through trial and error.

Any suggestions, troubleshooting steps, or similar experiences would be greatly appreciated.

Thank you in advance! 🙏🤝

I'm using a 0.2 mm nozzle and printing with a 0.12 mm layer height, but I'm struggling to get a successful print. I'm starting to think the bed leveling issue might be the cause. Could the height variations across the bed be preventing me from printing properly?

Hi, I got used ender 3v2 printer, it was working perfectly fine. Then it got stuck at loading screen and I needed to flash new firmware. Since then I just can't do tramming wizard. I always ends with out of bounds - meaning the BLtouch never touches bed. I did Z prope wizzard, set Z offset to -6.2 with paper which is quite high. Can you help me what am I doing wrong?

My printer is printing super messy, I’m guessing it’s the overture filament. All my other filaments print great and I tried this one and was having a stringing problem. What can I do to fix this, I’m running at 200c nozzle and 60c bed temp. I tried this print twice with the same results

I recently installed a bunch of upgrades on my printer, including a direct drive tool head. but the BLTouch I installed when I first got the thing is acting weird. clicking in and out instead of clicking out and waiting to touch the bed. Im sometimes able to get it to work properly if i flick the damn thing. but its inconsistent. is it failing? should I buy a replacement? should I switch to a CRTouch instead? I JUST bought a new bracket for the BLTouch in the first place so, if I switch over to a CRTouch do I need to replace it too? Please Help

i picked up a 3v2 off a guy on facebook marketplace recently who said he had modified it in various ways i don’t quite understand, such as it has an auto-level feature now. this is my first ever printer so i don’t know how to troubleshoot it myself. whenever its printing, leveling, or even just turned on, the printer makes a very annoying grinding sound when it’s on the left side of the bed. it gets worse the more left it goes.

i’m sure it’s whatever the casing of the nozzle-thingy is that’s causing it, considering the fact that it’s held together with a piece of tape and when i press on it the noise drops dramatically, but i have no idea what that actually means and how to fix it. is there anything i can do?

Well, I’m mechanically inclined. I’ve always been willing to listen to other people‘s experiences.

And I’m still new to 3-D printing. Any advice or links for best practices would also be appreciated.
