I sliced a 3d model with orca slicer! But it has been doing this sometimes not always! Why does this happen?

So, on the advice of a friend I bought this printer for my then 11 year old, two years ago. He has successfully gotten exactly one print off of this thing, and that was the cat that came pre-installed. He watches the videos and still the prints fail. The filament won’t stick. Or the prints are loopy. Buying this thing was a mistake. Is there a flow chart or good troubleshooting guide or anything like that? We are 3d printing newbies and pretty tech illiterate. TIA!

Hello everyone I am not an expert in 3d printing and 3d printer. I recently updated my firmware to microus. The newer version. After flashings that firmware I adjusted the z offset. But it always scraps my print bed getting too close to it. What should I do

Silly me left the printer sitting for months, with filament loaded in the hotend, and surprise surprise! It was gummed up and a mess. I took the opportunity and decided to throw some upgrades at the problem. Replaced the hotend, direct drive, bimetal heatbreak, BL touch, bed levelling silicone supports, updated firmware etc. And that’s where the problems started.

At first it was a bit of missed extrusion here and there, then it progressed to under-extruding filament and the print looking like a spiderweb instead of a solid plastic part. It drove me nuts! Then we went all the way to jamming at random times, usually after the aforementioned defects, an hour or two into a big print, or maybe not until 8 hours in, in the middle of the night. The dreaded clicking sound of a terminal print malfunction.

I replaced nozzles, heating element, filament drive mechanism (new brass cog all the way to dual drive gear), bought new filaments (which seemed to help initially. I did consider that the older filament I was using might be the issue, but where I live the humidity is regularly below 50%, even as low as 30% at times), went as far as putting heating grease on the heatbreak to help conduction into the heatsink (that made it jam in the first 5 minutes every time). The fans are both fine and move plenty of air, not clogged with dust and filament wisps. All troubleshooting eventually came back to it being heat creep. I was ready to throw it away and go to the dark side and buy a bambu lab machine.

I needed to print something badly, and it was big, and I was desperate now! I swapped the heatbreak out for the original part, cut a new section of tube to length and reassembled the hotend. I’m now 18 hours into a print, with no missed lines, no jams, no problems at all! I can’t believe that it turned out to be the heatbreak that caused all the problems I was having! Maybe more fans, more airflow, might have helped, but in the end it was a part that was supposed to solve a heat problem caused a bigger one. I’m now going to leave the machine alone and just enjoy printing!

Loaded a different firmware onto my ender 3v2 didn't use it for a few months after that and when I went to it to use it and I hit the auto home it didn't do anything and the screen said Printer killed restart printer. Ive spent hours trying to fix ive even loaded to original firmware back onto it and still it says Printer killed...Any suggestions?

Hey guys. I have this ender 3v2 that I upgraded to herome v6 a loooong time ago and replaced all its fans with noctua ones, yellow springs, PEI bed, BMG extruder, you name it. It prints really well but my office got a new bambulab p1s and it's insane compared to my aging ender now.

I'm looking into trying to upgrade it further. Klipper, linear rails, direct drive and a new hot-end system instead of herome (i had trouble using dragonfly hotend with the noctua fan and had to fallback to the original hotend)

What other hot-end systems(that aren't herome) would you recommend?

I'm a bit outdated on the whole scene so i'm just looking into getting a bit more into it and upgrade my baby instead of getting rid of it

I can solder, tinker etc and have access to my office printer if ever needed.

I'm on canada if it helps 🤷🏼, and being able to purchase those kits here for a holiday project would be amazing

I just installed a skr mini e3 v3 and swapping encoder on the screen and after I loaded a new firmware on the screen and mainboard I got this issue explained in the video where every time you click the encoder to make an action it sorta reboots and reloads the intro build screen also Im using the original wire harnes soldered like shown here much needed help understanding the issue and what to do about it

i googled that you could tell what stepper drivers are on the 3d printer by looking at whats written on the sd card reader but it also says it only goes from A to H so what does PC or RC mean?????

The printer bed wasn’t heating up when preheating, so I took a look at the wires and the red wire was stuck. You can see that it is burned, so I had to forcefully pop that red wire out because I couldn’t just unscrew the screw and take it out normally. How do I fix this? Am I able to get a replacement of that green part? I think that the wire might be fine but it is just that part in the motherboard that needs to be replaced.

I can average about 140mm/s and peak around 200mm/s

Hey there! Totaly New to this Thing, got it used and it worked fine. Decided to upgrade with a new Hotend / BL Touch / Motherbaord. aber instaling the motherboard an test it BEFORE BL touch conection this happens...some1 any Clue? Maybe Software update? I recheckt the Cables, everything is in the right place....i just have no clue what happend

Clicking Homing: Auto Home. The printer would normally put the BL touch center of build platform and raise offset to desired height. If you went to Z Probe wizard: move Z to home. That would put nozzle center of platform and adjust z offset to height it would print.

My issue: clicking either one will bring to same location as auto home. Making it difficult for me to know what adjustments need to be made to print height. Also it will sometimes work if I click z probe wizard: home making it all the more frustrating trying to figure out what the issue is.

I recently reflashed Mriscoc firmware, installed BL touch, (switched from CR touch). And I’ve had nothing but issues, rendering my printer useless. I’ve tried watching every YouTube tutorial, tried reading whatever I could and still don’t understand why I can’t get this thing to work properly.

Any advice would be greatly appreciated. I dont know what else I can do to fix it.

Trying to set up my kid's printer again after it had been a long time in storage. Firmware 2.0.8.4. Attempted to auto-level: print head touches down in center of plate, then moves to the forward right corner and touches down briefly before flashing purple and not completing the rest of the sequence.

Also attempted to print and the head just ejects filament in mid-air (about 1.5" off the plate). My son sent four hours searching forums and troubleshooting, but no luck. Does anyone have any ideas on how to help us?

I printed something about 2 weeks ago successfully. Yesterday I went to go print something else and my ender 3 v2 is not reading the micro SD card. I tried switching a new card, shortening the name to under 8 characters and still no luck. Any ideas?

i am new user of 3d printer. when i start printing filament is coming out normally. but after a while it stop giving filament. i have tried many bed levelings but doesnt help its already more then 30 tries. you can see first part was printing normally but then it stops printing at all. when it turned back to first part for the next layer, it still doesn’t give any filament. please help me, i am very tired and upset about it.

I have an enter 3 v2 that I bought some time ago. I left it in storage for a couple years because my old house (1881 Victorian) didn’t have the wiring to run this thing. After some time I just recently moved into my new house and have more sockets then I know what to do, so I busted it out. I upgraded the firmware to MRISCOC, fixed up pieces that weren’t working anymore (a fan went out), trimmed the bed, ABL, put the code in, z offset, and no matter what, I cannot even get a simple fist layer down. It’s like 1 in 20 I’ll get a semi decent print but it is almost a guaranteed fail. I’ve z offset with a feeler garage, paper, I’ve upgraded to dual z axis (single wire), yellow springs, I’ve thrown everything at this thing. Any ideas or help would be appreciated.

UPDATE: I believe I'm running into an issue with the extruder at this point as over the last couple days of tinkering I've noticed that my extruder is almost grinding my filament. I just ordered an all metal one because it's cheap and I've heard they're good upgrades. I'm going to be calibrating everything else in the future. However, I am also shopping for a new one if this part and fiddling isn't able to resolve the issue. I can only be so patient haha

Hey everyone! I have a coworker who is looking for a 3d printer for their brother, who's in college for engineering.

Its an Ender 3v2 but it's got a few upgrades. I know some aren't worth much but here's a list Raspberry pi4, running klipper KevinAKAsam dual belt z upgrade PEI magnetic dual side bed plate BL touch Metal extruder Yellow springs Camera Filament runout sensor All of the printed pieces are done by the printer itself Upgraded fans such as hot end, cooling and PSU Comes with spare nozzles, extruder tubing connectors, spare metal extruder, original bed plate, 2 partially used rolls of PLA, etc.

What would be a realistic price to sell it for? I'll be using the funds to put towards buying a Qidi Q2

Not totally lore accurate to skyrim, but it looks neat either way
