How to Fix an Ender 3d Printer Warped Print Bed

hi this Saoirse Purell with the dr. Beck's channel and over this fall season my wife and I are traveling to our four children's homes to visit with our children and our grandchildren and I'm the grandpa that shows up with a 3d printer this is the second under three Pro that I've delivered I've also delivered a quit e exmark printer and I deliver these for very selfish reasons I want to be able to spend time in different locations by children of our in four cities around the world and yet I still want to stay connected to by YouTube viewers so I want to make sure even when I'm traveling and periodically post videos one of the challenges that people have with an Ender printer with the exception of the Ender v plus that has auto bed leveling is that the print surfaces seem to be imperfect not perfectly perfectly flat and often they have a little dip in the middle or perhaps a little high spot a little bit more often a little dip in the middle this problem is exacerbated by the fact that the new print surfaces that go on top of the physical bed are flexible and so if you have a dip in the middle this is going to dip so we're going to look at how to solve this printer we're going to review how to quickly level your printer even if you do not find a bed leveling auto bed leveling option in your console and this will make it much easier for you to produce satisfactory really better quality prints so stay tuned and let's learn something together [Music] one of the problems that people with ender printers are facing is that the principles are not always perfectly flat in order to determine if your print surface is flat I recommend taking off your magnetic print bed and getting a metal ruler no you can't probably use a plastic ruler it might work or wooden ruler but I think you need a metal ruler they're not very expensive you put the metal ruler diagonally across the print surface and then you look underneath and see if you see light at any point if you see light in the middle the bed is dipped if you see light on the ends that comes up in the middle and you should try that in both directions in my particular case this print that has a slight deep in the middle so if I level this print that on the four corners when I go to do my first print it's not going to stick because the middle is too low what I found for this printer is that a single post-it note put on the middle of the print bed will solve the problem now why you might think that creates a lip but it doesn't because the magnetic print surface is flexible and it will flex to even that out then you can check again with your ruler and see if you can see light in the middle in this case it ended up pretty done flat in both directions but you may need to use more than one post-it note now after you have that post-it note in place I'll show you the procedure that I recommend for leveling the print surface and I recommend this even if you have one of the Ender printers that ships with firmware that has an option called Auto bed leveling unless it's the Plus model that's really a misnomer all it's doing is moving the printhead to the four corners and into the middle for you so you can do that yourself here the steps you need to take first your printer should be powered off in fact I'm not only unplug it just to make sure it's not powered on second don't worry when you go to move this print bed you may see your LCD panel flash don't worry it's not a problem the reason that's happening is a stepper motor is a DC motor DC motors when you apply power spin when you spin them without power they generate electricity so it's generating a little electricity causing the LCD to start to come on don't worry about that so what I like to do is move the printhead to about an inch in from each edge and then here's the next thing you need to understand about these printers when the Ender printer needs to determine the bottom position the home position for the z-axis it uses a little micro switch now I'm going to click this the reason you see this microphone in the view here is I want to make sure it picks up this sound so listen that's a very important sound the reason it's a very important sound is that you can manually lower by turning the Z rod the screw rod counterclockwise the z-axis and when you get to that switch you'll hear it click when you just hear it click that's the home position that's the position you should use for checking to see if your bed is low now your Vettius Springs under it so you can push down on it slightly slide a post-it note in once again I'm a big fan of post-it notes as a 3d printing tool and see if it just slides around a little bit but with a lot of friction this bed was previously leveled so it's pretty darn close so now I'm going to slide the print head over to the other side pressing down on the bed slide a post-it note underneath that one's pretty good to try this corner that one's pretty good slide it back to the other corner and try to add that one's maybe a little tight so I want to pull the bed down to do that I want to compress the spring so if I turn the screw counterclockwise it will compress the spring some more pull now it's too loose so I'm gonna turn it back a little bit and that's just about right and so now let's check the center that's pretty darn good so now that we have the bed level we can power it up and proceed with our print one of the nice things about the newer ender 3 printers is that when you're doing a calibration print perhaps just boxes and you're watching to see if it's sticking and whether you can rub it off as you're printing it you can actually turn these screws during the printer now you wouldn't want to do that during a production print because you might mess up the print a little bit but these are so easy to get to you can do that while you're printing so I'm going to power on this printer and we're going to do a calibration print ok our calibration print is well underway on the outside it printed a skirt that is in essence another calibration area you can check for you should rub on it to see if it'll rub off you'll see the interior lines you should feel that they are raised if those lines do not show up at all your nozzle is too low if they rub off when you rub with your finger your lot nozzle is too high so in this case they seem pretty darn good ok I'm going to pause the print now because we've printed sufficiently to get a good sense of this and we're going to turn off the printer and we'll wait for it to power down it will take a moment then I'm going to manually move the printhead up I find that easier than doing it with the front panel we'll take our print surface off and you can see here we have a very nicely printed calibration grid and none of the lines will rub off at all yet they are all raised above the surface so this is a perfectly calibrated printer thanks to one post-it note in the middle well folks I hope you learned something today if you did give us a thumbs up give me a thumbs up on YouTube subscribe to the channel more importantly I think a great way for other people to benefit from this channel is if you share the channel with people so share the URL for the video with anyone you know that might be interested feel free to share any of my videos in any user groups or forums thanks so much for watching and let's continue to learn things together
