THANKS SOOOOOO MUCH. I NEVER LEAVE ANY COMMENTS ON ANY CHANNEL BUT I AM SO GRATEFUL FOR YOU TAKING TIME TO SHOW THE WORLD HOW TO END THE FRUSTRATION!!!! OF THE SHIFTING OF THE LAYERS. THANK YOU MANY MANY TIMES!!!!
I don't use a filament spool. I stretch my filament out for hundreds of yards outside my house and let it feed through an open window. I hold on to the far end to keep it straight. It's tiring on long prints lasting days but my family brings sandwiches and Mountain Dew to me outside.
It’s best to run at 10percent infill or less first to make sure it prints without error . Then switch back to desired infill so your not waiting days for the test print
I tried printing two small to medium objects the other day and I think it was about 95% of the way through and all of a sudden the layers started shifting to the left!
I just had the very same layer shift problem after a 18 hour print.. I also heard a noise that I couldn't identify, at first I thought it was the nozzle touching some layer, but after watching this video I think is the spooler.. The last print before the 18 hour fail was a new spool holder that use ball bearings.. Now the rotation is very smooth but it tends to rotate more and the filament is a lot loose compared to the original setup where it was tension between the spool and the extruder due the friction, so it has to be the problem.. I tried to improve the noise from the spool rotation and I thought it was going to be an improvement, but at the end I created a new (and lot worse) problem. The moral of the story: don't fix what is not broken 😂
Holy Cow! I was having an issue where I started to get layer gaps. Turns out my filament was tangled on the reel just a tiny bit but it was creating too much tension for the printer to pull the filament through! Thank you for finding this issue! (mine happened near the end of a pretty large print as well so I feel your pain!)
Omg I've been pulling my hair out over this. I used a cheap brand (Inland) and while it honestly prints like a dream i noticed my first print had a broken strand, it snagged right out the bag! I rewound it continued printing and it was fine, then i waa experiencing layer shifts too. Ive tried so many things (my x axis does wobble but i'm having a hard time fixing it). In the end this is what fixed it. Thank you so much
I was almost switching drivers, this drove me crazy. I literally disassembled and reassembled all parts of the machine. It's the last time I'm printing and I'm hoping the problem is due to stupid filament jamming. I rewound the entire reel. thank you bro
Thanks! I troubleshooted a lot about the bed and tensioner belts, but it was my PLA filament just a *little* bit tangled that kept ruining overnight prints.
Great tip. I’ve been struggling to diagnose my layer shifting. It’s so inconsistent that it’s tough. I can definitely tell when it’s going to do it because it slams something hard but it’s not obvious what and isn’t always the same. I’ll try re-winding the spool.
Had my first misaligned print,blew my mind thought i had it dialed in and getting somewhere then im like whaaat the f like really now. After printing fine whole fn day just to spoil it on the finishing hour or so. Thank you glad i found your video.i noticed before once thought nothing of it till now .Ive thought why not put motor on spool in paralel to extruder,same idea as twin dual z rod? Working togetherpush pull etc..
Had exactly the same problem with two very long prints. Since I checken on all the mentioned possible issues, I might have had the same problem. I can't see any problem in the spool now. But maybe there was one in the middle of the night. Thank you for sharing!
I just got an Ender 3. I had meticulously set everything up perfectly, or so I thought. I ran into this issue for the first time stopped the print and turned to UA-cam. Sure enough, the spool has a tangle. I'm glad I didn't start trying to fix slop in the machine itself.
I'm seeing the same issue with a print now and while I haven't checked the motor gear screw or Z-axis, I did recently add belt tensioners and made sure they're tight. Though the smoking gun for me is that the Inland filament was very sloppily wound from the factory. Not the first time I've had that kind of quality from Inland. I'll see if it shifts with this print. If it does, i'll check everything you mentioned again and re-wind the spool.
Dude. Thank-you. I was having this exact same issue. I now know exactly the problem. I suspected it was the problem, but was unsure. As the issue occurred in exactly the same place on a print. Much appreciated.
Yoooooo. Thanks for this! Been through the steps to calibrate everything took the printer apart put it back together every replaced a motor. Finally stumbled onto this gem and boom solved!
Thank you so much for this video. Why is this problem not on the lists of common layer shift problems else where on the internet?! Tried everything before this, but this was exactly the issue 🤦♂️ thanks again
I had that happen to me on a 30 minute print. I also went into the printer control options and initialized the erom or eram. That fix alot of my issues with my ender3 pro.
No possible way filament snag would cause this. Ender 3 is not direct drive. If it were direct drive then this is a possibility because the filament actually moves with print head. With the Ender or any bowden tube type/fixed extruder type, if you bind the filament roll the extruder gear would skip and you would get unprinted layers. It would not restrict the print head from moving! Think about it. Personally we have been battling this layer shift for quite some time (on CR-10, T-REX, and now my Ender 3 is doing it). We have had positive results with cooling down the stepper drivers on the main board. Basically installing a bigger/better fan to keep them cool. This is still questionable iMO we have had positive results with it. UPDATE: Turns out the Ender 3 Pro has the motherboard fan connected in parallel with the part cooling fan and on the first few layers the part cooling fan is not running so the layer shifts I was getting showed up only on larger prints. Solution was to snip the connector off the motherboard fan and wire to the always on hotend fan screw terminals. www.reddit.com/r/ender3/comments/a2s2oy/ender_3_motherboard_fan_fix/
Thanks for the comprehensive response. In the past year this has never happened again to me. The only change was that I take care not to let my spools tangle. Could be luck but I doubt it.
speedybits the only thing I can think to do is test it. Kick off a short print, Lock your filament roll after a few minutes and see if the head gets restricted...
My spool's are always tangled I have to babysit them so the spool doesn't snag and stop the print. It doesn't cause print shift, but it does cause the filament to stop flowing so the next layer can gunk up as it doesn't have the lower layer to adhere to. I think the gunking up causes the shift...I'm getting clunks but it seems to me the head is bashing throught the gunks and gets stuck for a bit before it pushes through causing the stepper to skip.
The overly tight belts per Dosclic 98 sounds like just the kind of thing that would do it. Several videos insist that self-tangling (one loop moving under another loop) is a physical impossibility. They say you have to lose control of the end of the filament at some point (like when you're threading a roll to the machine and the end of the filament slips out of your hand) and while you're not able to see what's happening, the end of the filment threads under another loop.
I had the exact same problems with layer shifting after some hours. For me it was the Z-axis threaded rod which was not tighten enough to the motor. On higher layers some times there was no tention and the nozzle did not go higher for some layers. So the simple solution was to really tighten the Z-axis threaded rod. Since than i never had this issue.
Really rewinding is not the best solution, because spools can actually get stuck like that even if they are perfect at the start, specially when you have less filament on the spool and it has become light. You will experinence the filament unravelling itself in bursts and getting caught under itself frequently. You should make it so that there is constant tightness between the spool and the filament guide and you will never have that issue again. Make the filament guide have friction against the filament and the spool have a slight drag when pulled on by the printer.
That was a long winded way to say your spool was snagged. When I saw the first print I thought maybe a cable is getting in the way or binding movement.
After re-winding my 2 spools, I now very carefully prevent tangles from happening when changing them. Haven’t had the problem ever happen again in the last 10 months.
I had the exact same setup with the spool on top and the 3D printed filament guide. One day it just got crushed. Since then I have my spools on a 3D printed holder left of the printer so the filament is going as straight into the extruder as possible.
Thank you guys for your reply. Since posting my problem I found that the lever arm on my extruder was cracked , rendering the spring tension very ineffective. So my filament was restricted but not in the same sense. I bought an aluminum replacement and all seems good. I'm not quite sure how this relates to missed steps but I haven't had any issues since.
That kind of shifting couldn't had happen because of filament got stuck. Even if you had forgot to put any screws on the vertical aluminum bars and the extruder was pulling with a force of 100J still the Z axis wouldn't budge because of the reaction force. If you imply that the extruder is dragging just the Z bar , the wheels that mount the Z bar on the vertical bars normally don't have more than 1mm tolerance of shifting left-right. Had your wheels be that loose to allow that kind of shifting the Z bar would had come right off before the print even started.
James Black thanks for the feedback, but this was the root cause. I finally caught it in the act while I was working next to it all day and saw it trying to pull from the tangled reel.
I agree with James, I don't think this was your cause even though you are convinced it was. A tangle would not cause a perfect shift in layers. I have done probably 20 prints and 2 had a small shift like this. Never had any filament issues. In fact I never made changes or adjustment. It seems to be random for me anyway. I have a bad print, reprint without changes and it's not there. I don't know. Obviously filament snag is not good though.
This issue is caused by your nozzle knocking your print then at some point shift it, because of one of your smallest print corner will go higher when it dries during the print. I have this many time such as im printing a lot of hollow car models who have really tiny corner and lines. The solution is to stay close and when it start to bump against the part see where it bumps then cut a bit of it while it’s still printing.sounds crazy but troubleshoot some Really hard prints. The tangling of the filament can only cause what they called ghost layers such as your filament cannot arrive in the nozzle because already blocked at the spool level so the nozzle will just continue his journey without any filament coming out. U have solved it by changing the filament who must to have another behaviours when drying in those tiny corners.
808Beam News I’ve heard people say that too, but I have a hard time believing it could move and then stick itself to the plate again. Plus The main problem 3d printers are notorious for isnt the random skipping, it’s when it skips *consistently* on the same layer every time. That’s what I’m still trying to find an answer to.
tnk u man , for your time to make this video. I have to a layer shifting :) after each layer 0.5 mm shit on y axis, i will look at that . tnk u. All tip are 👍
Thanks for the upload, im going to check my feeding arm as i have noticed it isnt entirely smooth and have heard it click as the filament clips on some rough edges of it and I'll check my spool cause I have wasted 2 4 hour prints now
Thank you for this video. I just started 3D printing myself and I have an ender 3v2 and I was attempting my largest print yet, not quite the size of the part you were printing. I had a GNARLY layer shift in my print and this is going to help me make sure my spool isn’t tangled.
Omg, thank you so much! Never would've though to check this... Luckily I didn't have to print something nearly as large as you before experiencing this issue.
Yeah this happened to me on my anycubic mega x, during a 5 day print of a mando helm for my son...twice... and now on my latest attempt of a lightsaber stand... i thought it was a coding issue through cura. that's why i tried a different print. I'll have to check my spool...
Fantastic video dude! My new Geeetech A30T has the exact same problem. I have noticed the tugging as well. Will look for a solution to winding problem. Thank you so much for this video though!
usually when i experience shifting i dont have time or mental capacity to dall this so i just accept it and sand it down and if it does what i inteded it to do then I will make myself a bowl of cereal
So basically a good thing to try for fixing layer shifting while printing is to take the spool of filament off and unravel it until you find where it’s tangled up and then re-wrap it. tight and that should fix the layer shifting problem?
wow yea i have been having this happen and i looked at my spook at it was a mess! i changed spools and wasn't sure what the other was like but yea i'm going to look closer into this.
I think you hade two difrent faults. The first one looks like when the nozzle has been draging because of combmode. Keping within the object to dont get strings. Now and then the load gets to high for the motors so they skip steps. The otehr one is only unlycke to get a spool that stucks. Was the G-code produced with Cura and combmode active??
wait whaat ?? it's not a printer problem ? this is weird ... but i'll definitely try to check the spool next time. The thing is, i experience this on my Ender 5, but the spool as far as i can see it's perfect. It's a brand new spool that was never removed and reintroduced, so i can't see how the filament could be twisted. Anyway, thanks alot :)
I'm sorry for you but you didn't solve the problem... you got lucky that the last try didn't fail but layer shifting is due to the X or Y steppers skipping steps (sliding if you prefer) and that is due to the motor not being powerfull enough in a particular moment of the print. You havr to check temperatures on your stepper motors, if you can barely touch it (80°C) the magnets inside will lose their magnetism to the heat and the stepper motor will skip steps. On the other hand if it's too cold it means that your stepper motor doesn't recieve enough Ampers (you can check on the internet how to adjust that depending on the printer you have). Low amperage leads to stepper motors skipping steps too. Another problem you might have created is increasing the acceleration values eather on your slicer program or in your 3d printer settings and if your stepper motors aren't powerfull enough to make that acceleration they'll slip (skip steps) and you will end up with failed prints.
i am having the same problem with my ender 3 but what i think in my case the 1 kg spool is kinda heavy which jerks when the motor tries to pull the tangled filament.....this jerk causes layer shifting after 10 mm of vertical print......design of spool placement over the printer is really a bad idea...better to avoid such top loaded spool printers
Happened to me. I'm curious as to how you didn't notice it the first time. When it happens the filament usually is almost completely vertical going from the spool to the extruder because the extruder is pulling so hard
sorry.. how did that cause the shift? should it be jammed filament cause no filament to the hot end meaning you'll have air print? was there in any way that that filament jam pulled on the y axis?
i had something like this happen to me with ender 3 pro. I also caught it in the act with the filament snagged while the extruder tried to drag it left and right. It's very frustrating indeed.
I just found out that if yours is over heating in the main board box if you clean the wires up and keep them from going over the board ot will fix it to
Had made a roller for my printer. After 13 hours I saw a similar shift in my print. So I checked everything. ...Except the huge roll that was missing on top (now laying on the floor)....
In general, i don't think this is the correct diagnosis, as the result assumes that the other material spool also had the same tangled issue which most probably is not the case. personally, I have had this layer shift in multiple prints but the solution you have mentioned is not related. In a direct drive extruder, it might affect the movement but in the Bowden system, it should not.
It is actually very easy to accidentally cause a tangle if you don't grab the filament carefully when you back it out of the extruder. I'm sure I had done this to nearly every spool.
I've been having lauer shift issues. I've been hearing popping sounds. I don't understand though how the tangle makes any difference though. Its a bowden setup, so the extruder doesn't move
@@mishaisspeed after a full disassembly and reassembly, I no longer have the issue. I think it was probably related to z axis setup causing the far end to droop. May also have been a loose print head
I'm confused. If you accidentally tied up the filament, wouldn't this be in the outermost side of the spool, and not towards the end of a 20+hr print? Or were you pausing these and removing the spool and then restarting?
Aaah... It's not a "spool" problem in my case. My Ender 3 v2 has shifts randomly at least after 1 hour of print time. But! It's always "x" and "y" axes at the same layer. Still don't know how to deal with it... Firstly its stepper motors were overheating and i lowered current a bit. Temperature gone down but the problem still remains
My screen on my printer goes blank every print after about 30 mins. Also it sometimes stops mid print. Ive wasted two full spools of filament so far. Any print 3 hours or under is fine, but anything higher it fails. Sometimes it may print as long as six hours if im lucky.
I came looking for answers to my ender 5 plus layer shift issue. I was about to dive down the rabbit hole of driver stepper vref's on a silent 2.2 Mainboard. I thought i would double check everything fully. I removed the x-axis roller and tensioner, I had Adjusted the top screw above the bearing thinking it was eccentric but i was simply locking the roller assemble. Had to remove and adjust before reinstalling. Hope that helps somebody else.

Damn I should’ve thought of that. I flushed one end of the filament down the toilet and the printer just pulls it out from there.

I had the same problem after changing filament on my Ender-3. It was tangled. I´ve never had layer shifts before and untangling the spool fixed it.

Thanks for the upload, im going to check my feeding arm as i have noticed it isnt entirely smooth and have heard it click as the filament clips on some rough edges of it and I'll check my spool cause I have wasted 2 4 hour prints now
Same problem never thought of this but will try
thanks
Thank you man
Sorry for your loss
Thank you so much. I faced the same issue here. Now, the printing is going smooth.
Thank you for this video. I just started 3D printing myself and I have an ender 3v2 and I was attempting my largest print yet, not quite the size of the part you were printing. I had a GNARLY layer shift in my print and this is going to help me make sure my spool isn’t tangled.
Dude this might be my issue too! Thanks for posting this!
Omg, thank you so much! Never would've though to check this... Luckily I didn't have to print something nearly as large as you before experiencing this issue.
Yeah this happened to me on my anycubic mega x, during a 5 day print of a mando helm for my son...twice... and now on my latest attempt of a lightsaber stand... i thought it was a coding issue through cura. that's why i tried a different print. I'll have to check my spool...
Thanks for taking the time to share this. Much appreciated!
Fantastic video dude! My new Geeetech A30T has the exact same problem. I have noticed the tugging as well. Will look for a solution to winding problem. Thank you so much for this video though!
Also my first ever reply to any youtube channel ever. Thank you again dude. Subscribed. Please make more of these videos.
usually when i experience shifting i dont have time or mental capacity to dall this so i just accept it and sand it down and if it does what i inteded it to do then I will make myself a bowl of cereal
So basically a good thing to try for fixing layer shifting while printing is to take the spool of filament off and unravel it until you find where it’s tangled up and then re-wrap it. tight and that should fix the layer shifting problem?
This video makes me very mad. That simple of a fix that I overlooked. XD thanks!
wow yea i have been having this happen and i looked at my spook at it was a mess! i changed spools and wasn't sure what the other was like but yea i'm going to look closer into this.
Appreciate your painful research!
Always!
Great I did have that issue I wil try looking at my filament spool agsain.
thank you - i think you solved my problem too
Thank you SOOOOOOOOOO much! Btw that is the worst possible layer shift!
now i made up my mind to be willing to pay for a spool holder...
Awesome info I am going to try this thanks.
Thanks you so much dude this is the best vid on yt
I think you hade two difrent faults. The first one looks like when the nozzle has been draging because of combmode. Keping within the object to dont get strings. Now and then the load gets to high for the motors so they skip steps. The otehr one is only unlycke to get a spool that stucks. Was the G-code produced with Cura and combmode active??
Just got around to reading this. Thanks for the suggestion. Yes I was using Cura but I don’t recall the mode. I’ll keep an eye on it.
wait whaat ?? it's not a printer problem ? this is weird ... but i'll definitely try to check the spool next time. The thing is, i experience this on my Ender 5, but the spool as far as i can see it's perfect. It's a brand new spool that was never removed and reintroduced, so i can't see how the filament could be twisted. Anyway, thanks alot :)
🏃🏃🏃 me running to check my spool, thanks!
Thank you so much you saved me so much time!
Another perfect print! Congrats! Lol.
i had simular isue put some lube on the inside of the spool so it spins easier and ordered some bearings going to print a smoth rolling spool holder
I'm sorry for you but you didn't solve the problem... you got lucky that the last try didn't fail but layer shifting is due to the X or Y steppers skipping steps (sliding if you prefer) and that is due to the motor not being powerfull enough in a particular moment of the print. You havr to check temperatures on your stepper motors, if you can barely touch it (80°C) the magnets inside will lose their magnetism to the heat and the stepper motor will skip steps. On the other hand if it's too cold it means that your stepper motor doesn't recieve enough Ampers (you can check on the internet how to adjust that depending on the printer you have). Low amperage leads to stepper motors skipping steps too. Another problem you might have created is increasing the acceleration values eather on your slicer program or in your 3d printer settings and if your stepper motors aren't powerfull enough to make that acceleration they'll slip (skip steps) and you will end up with failed prints.
Thanks !!! You help me very much...
Happy to help
That's the first thing I check, wish I knew why my layers keep shifting.
I don't understand why that would cause a layer shift though, I would expect the symptom of that problem to be under extrusion of the filament
i am having the same problem with my ender 3 but what i think in my case the 1 kg spool is kinda heavy which jerks when the motor tries to pull the tangled filament.....this jerk causes layer shifting after 10 mm of vertical print......design of spool placement over the printer is really a bad idea...better to avoid such top loaded spool printers
upendra chaudhari you may want to start with a fresh spoil, or there are some other UA-cam videos on how to re-wind a spool.
My cr-10 makes the same problem, an there the spool is not hangiing anywhere on the print bed construction.
Happened to me. I'm curious as to how you didn't notice it the first time. When it happens the filament usually is almost completely vertical going from the spool to the extruder because the extruder is pulling so hard
I think that's been my problem. Thanks for sharing.
sorry.. how did that cause the shift? should it be jammed filament cause no filament to the hot end meaning you'll have air print? was there in any way that that filament jam pulled on the y axis?
Thanks I upgraded my printer and came across this same issue and couldn't figure it out
i had something like this happen to me with ender 3 pro. I also caught it in the act with the filament snagged while the extruder tried to drag it left and right. It's very frustrating indeed.
I just found out that if yours is over heating in the main board box if you clean the wires up and keep them from going over the board ot will fix it to
Thank you
Had made a roller for my printer. After 13 hours I saw a similar shift in my print. So I checked everything.
...Except the huge roll that was missing on top (now laying on the floor)....
Thanks - much appreciated
5 years later and here I am. :-)
In general, i don't think this is the correct diagnosis, as the result assumes that the other material spool also had the same tangled issue which most probably is not the case. personally, I have had this layer shift in multiple prints but the solution you have mentioned is not related. In a direct drive extruder, it might affect the movement but in the Bowden system, it should not.
It is actually very easy to accidentally cause a tangle if you don't grab the filament carefully when you back it out of the extruder. I'm sure I had done this to nearly every spool.
Thank you for sharing this vid.
Are cables getting stuck on something like the stepper motor? I say this is likely because of how you had shifts in more than just the x direction.
I've been having lauer shift issues. I've been hearing popping sounds. I don't understand though how the tangle makes any difference though. Its a bowden setup, so the extruder doesn't move
i agree with you, did you figure out problem?
@@mishaisspeed after a full disassembly and reassembly, I no longer have the issue. I think it was probably related to z axis setup causing the far end to droop. May also have been a loose print head
I've just had this happen to me change filament and the print and shifted didn't know what the issue was now I know
Thank you so much. I needed to know that.
Why would a filment jam move the X axis one direction or another? Was the head just not able to move to the proper X location because of that?
I'm confused. If you accidentally tied up the filament, wouldn't this be in the outermost side of the spool, and not towards the end of a 20+hr print? Or were you pausing these and removing the spool and then restarting?
Thanks for the video
Aaah... It's not a "spool" problem in my case. My Ender 3 v2 has shifts randomly at least after 1 hour of print time. But! It's always "x" and "y" axes at the same layer. Still don't know how to deal with it... Firstly its stepper motors were overheating and i lowered current a bit. Temperature gone down but the problem still remains
thanks a lot
My screen on my printer goes blank every print after about 30 mins. Also it sometimes stops mid print. Ive wasted two full spools of filament so far. Any print 3 hours or under is fine, but anything higher it fails. Sometimes it may print as long as six hours if im lucky.
I came looking for answers to my ender 5 plus layer shift issue. I was about to dive down the rabbit hole of driver stepper vref's on a silent 2.2 Mainboard. I thought i would double check everything fully. I removed the x-axis roller and tensioner, I had Adjusted the top screw above the bearing thinking it was eccentric but i was simply locking the roller assemble. Had to remove and adjust before reinstalling. Hope that helps somebody else.
It happened to me on a 2 day print wasted a lot of filament!
Thanks for posting this helpful information
so the filament was cursed. good to know, i aint touching my black petg anymore 😂
