Ender 3 Pro Bed Wobble – How to Fix It!

hey guys for a pre-30 prints cape today i wanted to go over how to fix a wobbly build plate if you look down here you can see that this build plate is kind of wobbly or really wobbly right now it got knocked a little bit by my kids so I just want to do a quick video show you how to fix that so before we get into that let's talk about why you need to fix this so what it will do when this is moving back and forth that you'll get ships which can cause ghosting and sometimes layer offset and then it's also going to be more difficult to level the build plate the process isn't difficult at all you just need a couple tools and about five minutes here I've got an Allen wrench they can't let the set and then if you still have the actual wrench that came with the set you can use that I couldn't find it so I just grabbed a replacement here but it's an eight millimeter wrench you're gonna need alright so let's go ahead and get started before we do make sure you guys hit that like button and subscribe if you haven't already it'll really help us out thanks alright now that we've got a close up of the build plate let's go ahead and kind of show you what's going on here it got knocked pretty hard by one of my kids so now if I'm moving this around you can see it's kind of shifting and as it goes back and forth it's gonna shift as well so I think we'll be able to fix it by just just tightening the bolt underneath it but if it ends up not fixing the issue I had at least it'll walk you through the process and how to actually fix the wobbly part of the build plate so let's go on and flip this thing on the side and get started I like to lean it on the left side if you're looking out in the back or the right if you're looking at it from the front or just assignment the power supply you can get a decent flat surface every other angle you're going or working with you're gonna have stepper motors or something else in the way so for me I've always found the easiest side there's it going to be the side of the power supply so it's going to do that real quick alright so we have our four wheels here one two three four we just got to make sure that they're not loose moving back and forth which it looks like a couple of these are it's also important that if you're just setting up this for the first timer any printer for the first time really that you go through and make sure that they're tightened down appropriately alright so let's go and grab the tools here like I mentioned you're going to need the allen wrench that came with the printer which is this guy and then a wrench this is eight millimeters like I said I couldn't find the one that actually came with the printer it's around here somewhere but this works just fine alright so can't quite show you this part but the actual nut is on the top side of the bracket so you've got to actually put the wrench on the top side and then you'll use the allen wrench here on the bottom side to actually tuck in it um it's difficult to get this in here and in place so I just kind of get it aligned and hold it and then just do the tightening from this side all right so we got a nice little snug turn there and then you don't want to over tighten it because if you start to dig into the wheel what that's going to do when it's printing is you're gonna get little bumps which can cause some random lines on the print or extra blobs I can show you example of a bad one here I'll add it to the printer I'm sorry I'll add it to the video real quick so let's tighten this a tad more alright so that one seems okay it's snug but not too tight we might have to go back and adjust it again but now we'll do this one all right same thing here we're still getting a decent bed of movement so let's take a look at the other side while I'm doing this I did want to make a note here to be careful we have our wires coming up to the heating element here and the actual thermostat you don't want to knock those out it could cause issues with the actual heating of the bill plate and if you mess up the thermostat you could potentially have issues with the temperature not being accurate or just running away and the default firmware on the Ender doesn't have any type of temperature one run away protection which is going to be why I'm upgrading it to the Merlin so just keep an eye on that just be careful working around this alright so let's go ahead and get to this side sometimes you gotta fuss with it a little bit here [Music] [Music] all right I got a little bit of a turn on that guy then let's go from the back here to try to get to this one it'll be a little bit easier if I wasn't trying to show you guys I'm kind of fighting images of the angles here all right so we're connected and we got a little bit of a turn there too now let's take a look here we still have some give that's looking like it might be from this wheel so let me try to tighten that again I might have to use a little bit more torque [Music] that's still turn good all right there we go I think that's good now let's go and flip it up and see how it works yeah that's much better you might need to adjust this piece again just a tad bit more but I think overall it would be usable at this point one thing you're gonna want to do once you make the adjustments is just go back and forth with this a little bit make sure that as you're doing that and nothing is catching and that it's going smooth if you're hitting any type of stops or if you feel like a random jerk or bump you're gonna want to try to adjust that figure out what the cause is because that will impact the print significantly all right guys that's the process to fix a wobbly build plate as you can see it wasn't difficult at all it only took about five minutes maybe less and you can get back to printing I would recommend you check to make sure the bill play is stable every time you go to level the printer so probably every three to five prints unless you have an auto bed level kit and then you'll want to check it maybe every five to ten prints just go through and just just make sure it's not moving and then it's stable if you have any questions go ahead and leave a comment below I'll try to get back to you as soon as I can and if you haven't already make sure you hit that like button and subscribe it'll help us out thanks talk to you next time
