In that time I've replaced, upgraded, or added to almost every component of the machine (often using parts the machine itself printed).

I recommend using three feeler gauges: Your target initial clearance, the next thickest gauge, and the next thinnest gauge. Set the initial clearance with the target gauge and then use the other two gauges to confirm. The thinner gauge should slide under the nozzle without contact and the thicker gauge should hit the side of the nozzle.

[@jpaugh64]

Oh, I get it. At first I read "next thickest" as the thickest one you have, minus one. You mean, the next thinner guage from the final tramming height you're aiming for.

[@lucassolomon1079]

In firearms the two over/under gauges are called "Go" and "No-Go" gauges. If the bolt closes on the No-Go gauge(larger than spec) it is unsafe to fire since clearances have become to loose, and if it can't close on a Go gauge(smaller than spec) the clearances are too tight and could be equally unsafe to fire. If it closes on a Go gauge but does not close on a No-Go gauge(in between the to dimensions) then the firearm is within safe firing specifications.

[@endz0r]

How do you know what the target clearance should be?

[@jpaugh64]

@@endz0r The advantage of a feeler guage is that it has its clearance printed on its side. It doesn't matter which clearance you choose. It just matters that you know your clearance, and you move the z-axis to the right height. Say your feeler guage is exactly 0.45 milimeters. Then you move your z-axis to 0.45, and you keep adjusting the bed height until the nozzle rests on the guage without pushing or moving the bed down. When you're done "tramming" the bed, you know that if you move the z-axis to 0.1 mm, the nozzle is exactly 0.1 mm above the bed. Does that make sense?

[@joeskis]

@@jpaugh64 no. Why move the bed up at all? That's just decreasing the total height your print can be. What else could it possibly be doing? Nozzle distance is different than bed height, surely?

As a former engineer with tons of machine shop experience, I’ve always hated the term bed leveling. I level using a feeler gauge, but I take one more step.

Also note that when you are leveling and using a piece of paper try and use a different part of the paper at each corner (and center) as the paper might get dented when you are feeling the distance (like writing with an empty pen). And also before you do feel for the nozzle height. You are heating the nozzle already and a tiny bit of filament might have already oozed out of the nozzle or starts to ooze out during the leveling giving tiny skewed results.

[@stonefish98]

I don't know if it's the "right" answer, but I've been preheating my bed to printing temperature, and my nozzle to 70% of printing temp. It's hopefully close enough to get the thermal expansion close enough for levelling purposes, but not hot enough to let it drip.

[@davidstorm5428]

His last point about bed leveling is very interesting. Based on this idea, you really don't need to go out and buy feeler gauges. You can just use any solid metric item (such as an Allen wrench or raw scrap metal) and hop the Z axis to the size of that item.

I tested them and they worked OK, but i don't use them now since i decided to print on glass. What i have now is just something i cobbled together from random junk i had, a micro 3.7g servo dangling a short leg with a mouse button switch. But then i have the pins on my board to wire a dozen pieces of extraneous equipment to it, so my situation is of course different. Anyway you connect ground of the sensor to ground (available on endstop connector), supply to 12V (splice from a fan or something), and the output via a diode to the active pin of the endstop connector. Diode points with the marked line towards the sensor! It will allow the sensor to pull down the board pin to ground (or nearly so well enough to read), but will not allow to pull it up beyond internal pull-up of the processor. A suitable diode type is standard small-signal diode, 1N4148. Silicon rectifier diodes shouldn't be used, because they're slower, and during switching can leak a high voltage spike. A Schottky diode can be fine, but might be an extra risk and there's no need in it at all, standard diode is good.

3D printing used to be called "Rapid prototyping" and I first saw it in use as early as 1997. Resin printing, basically. I think what created the media moment for 3D printing was the success of the open source movement around filament deposition.

[@liveen]

If it's an ender 3 / pro / v2, get new springs, the orange stronger ones. That, or 3d print the spring guides for it. Your levelling isn't the problem if you went through 17 times in one single levelling go, it's the springs buckling or the mounting plate not staying at the right place on the screw. Could also be the cable connector at the back, since that one goes out of angle easily on the ender 3 v2 that I have (until I got the guides). If you're levelling 1 time, or even 2 times per level "session", then you're also unlevelling it. You have to remember that if one side goes up, the other goes down, ON BOTH AXES. Because of this you don't instantly reach level, you gradually move closer and closer to it, so you'll need to go at it about 4 or 5 times to get a decent result if you have to start with big adjustments. If you get new springs and the guides you'll at least have to do this much, much more rarely. For anyone else with an ender 3, get yourself the Jyers marlin firmware with manual mesh levelling (CHECK IF YOU HAVE A 4.2.2 OR 4.2.7 BOARD FIRST), and you won't really ever have to adjust the screws again. Make sure they never change (guides and fasten completely, go back 1 rotation, then kinda level it okay-ish) and then do the "create a new mesh" thing in the levelling menu. You'll use microsteps on the nozzle to reach level (which means no touching or pushing the bed, great!) and it creates a mesh for compensation, sort of the same as the BLTouch! You'll also have to make sure to add the correct starting GCode in your slicer to make sure the printer uses the mesh for it's prints, otherwise get ready for spaghetti. (make sure to adjust the endstop switch thing on the side tho since you fastened all the level screw thingies and might need to go lower than that thing allows)

[@raffaelrubio4092]

@TheFryPo Well, first of all, I would give a little more thought to how you express yourself here. So there are several factors, on the one hand we are talking about a printer which costs about 250 dollars new. In this price range, it is hald often so that not all Tolleranzen adhered to. In the production it is also never possible to make everything perfect. The Ender3 V2 has a few problems. It is also a very big matter of luck. I have seen a couple who made out of the box everything great. Others had many problems, fortunately there are enough prepared files. When leveling make it so long until you have a passage at which you no longer have to adjust anything. It is a matter of practice. But there are also other factors, ev some glue. You can buy these for the printer or even a glue stick can work wonders. Otherwise you can also try to increase the temperature of the bed to 65 or even 70* This is no problem with PLA.

A dedicated video on levelling the bed using the Feeler gauge would help a lot

[@someguy2741]

You don't need a video. Follow the paper method. Go to an automotive store and pick up a feeler gauge set... it looks like a swiss army knife except with a bunch of flat sheets of steel. They should have metric and imperial thicknesses etched on them. Choose the one that matches say 0.25mm... adjust the head to touch it until there is a slight drag. Now you know where 0.25 above the bed is. Adjust the z stop in the software to be 0.25 lower so the printer knows where the bed actually is. Run the home command. Then lower the nozzle to Z = 0. The nozzle should just barely touch the bed. If the bed moves then the nozzle is too close. Adjust the Z stop or offset Done. If the nozzle is really far away then you didnt add the 0.25mm to the z stop value in software. If you do this check before printing then you wont drag your nozzle through the bed :p Note that your bed will have a certain amount of warping when cool and when heated it will be different so you might want to also try lifting the nozzle to your first layer height... say 0.3mm then move the nozzle all around the perimeter and through the y 0 axis to make sure your nozzle doesnt contact the bed. You can do this while cold and heated to verify it wont hit. A BLtouch and Bed visualizer plugin for octoprint gives a beautiful 3d mesh of your bed. It is not very flat. Even on a thick mirror it isnt very flat.

[@neutrality86]

Another big one is that "automatic bed leveling" is a misnomer. The concept is more like "automatic topology adjustment", since it's not actually physically affecting the bed. An "ABL" probe is actually measuring the bed and adjusting the height of Z according to the topology of the surface, and as such it has an overall tolerance for how "slanted" the bed can be before it stops working altogether. ABL probes are not sufficient enough to correct major deficiencies in hardware, you still need to level your bed relative to the XY plane of motion for a probe to do its job effectively.

When I started my 3D Printing journey I discovered the metal of a Diet Coke can was the same thickness as a piece of paper. Advantages: It was always constant thickness and moisture proof, it did not tear if I got the build plate too close to the nozzle, I did not have to worry if I had a needed note on it, when I felt it was too marked up it was easily replaced. Thanks for all the great videos.

FWIW, standard wall thicknesses in aluminum beverage cans in the states tend to hover between .0030” and .0035” plus a little for coating. BUT, it’s seldom the same thickness all the way around due to the challenges of maintaining alignment during manufacture it may be a touch over .004” in some places and barely .003” in others. It also gets thicker near the top and the bottom. I bet it works pretty well though. I’ve certainly used it for shims more than once.

Bear in mind that most printers for personal use come with their own levelling card to use to set the printer. It’s possible that the printer OS has a feature that deducts this thickness from the set value. You can also set your slicer to print a single layer skirt around your print and after printing, measure the skirt thickness to check your adjustment. The skirt should be the thickness of your first layer.

Great video ! The part "No, you're not leveling : you're tramming" was spot-on. Funny enough, 2-3 years ago I've been "gently" bashed when saying the exact thing you did : "paper test is flawed, use feeler gauges instead". People never learn and, when they were struggling with their first layers, mine were consistent at every print without elephant foot artifact. I do use the smallest gauge I have to achieve this, which is 0.04 or 0.05 mm. Suggestion : do a "3D Printing myths : extrusion 101". Lots of misconceptions and misnomers on extruder styles and filament drive styles did spread over the years and these need to be addressed too (since not only end consumers are concerned : companies too). ;)

They're not tramming. Tramming measures the perpendicularity between a head and the table. There's no way you can measure that on a 3D printer. You turn the spindle around when you're tramming. 3D print heads don't rotate. Least ones attached correctly don't.

Can't stress more the difference between "levelling" and "squareness" - noticing your X axis gantry is off by 0.5 degree after you printed a large gear is pain. On the other hand, if all the axes are perfectly perpendicular, levelling is only required very rarely or after changing/adding bed plates for different materials.

[@NZSpides]

I spent hours making sure my printer frame was square when I was building it. It paid off in the end. I rarely need to make adjustments to the printer now when I start a print.

[@LadyTea]

you are leveling your bed to the squareness of the frame. IE traming.

[@e_neko]

@@NZSpides Me too, but apparently the gantry was not screwed tightly enough and the end farther from the z-screw sagged a bit... just enough to make cylindrical stuff print off axis.

[@NZSpides]

@@e_neko 😂 hate finding lose screws after a build.

[@gabiold]

@@LadyTea Just partly true. You level the bed to compensate for the offset to the Z home position. A well built frame technically could work with just adjusting the Z home sensor position given the bed is already set parallel to the XY plane. But while typical 3D printer beds are not designed rigid nor accurate enough for this, there are more screws to achive tramming too, in Z direction. But there aren't any in XY relation, so one still have to make it accurate partially. But why not just make it completely accurate? Non-squared frame will never give you dimensionally correct parts, which does matter when you use it for scientific purposes.

[@SirTools]

Wish this paper thing was explained years ago ! After some trial and errors I gave up the paper trick and did adjustments on the fly per say to get that first layer right. Also I notice there is some variable to the z stop and limit switch. That for me was the ticket to getting the bed set correctly by limit switch / time vs actual mechanical stopping distance.

This isn't really a misconception that I've outgrown; rather, it's something I noticed YEARS ago that I have NEVER been comfortable or satisfied with -- and you touched on it EVER so briefly (8 minutes in): the use of FOUR adjustment points rather than THREE! Anyone who has used an old-fashioned transit or level for surveying or laying out building footings or such (prior to LASERs becoming affordable/ubiquitous) will surely have noticed the simple use of the THREE point leveling. To get a grasp of the problem, consider it in reverse: think of starting out with all four points PERFECTLY coplanar, precisely where you want. What, then, if you move any ONE adjustment? Well, obviously, the other three are STILL coplanar and the moved culprit is now either flapping in the breeze (assuming the adjustment is only FORCED in one direction but SPRUNG in the other) or pushing its corner OUT of the perfect plane -- and WHAT WOULD IT TAKE to remedy this? Well, it's COMPLICATED - but this problem simply does not exist in the 3-point system! As a slight hint, I propose something that I've never (in all my years in this community) heard discussed or considered: you really should work DIAGONALS in order to deal with the hypothetical problem. And (back to the forced one way and sprung the other) pay attention to what happens when you reach the end of the spring's reach (or the end of the threads).

BUT then I came to print a little spacer just 21mm diameter with some 3mm holes in it. It was my design on Onshape and I spliced with Cura 4 .10. The little thing would hardly print at all in the centre of the bed and I messed about and stuffed up the level. Several levelling attempts were still no good so eventually I homed the nozzle, raised the Z by 0.1 and I used a 0.1 steel feeler to set the gap.

Totally agree with the leveling. I use the paper as a first guide, doing it 3 times as when you adjust one side of the bed, the other points can go out of whack. Then I print a model and manually adjust while printing -like you do- to get the perfect height for the first layer. Don't forget that after a few prints, it may change height slightly, so every 3 or so prints check that it is still the right height by checking the brim is still nicely put down😃.

Same. Still remember that part in MGS as a kid being utterly confused as to why Hideo was on my screen and I couldn’t see the game. Thought something was wrong

The easiest way to make sure you are at the "1st layer" when leveling your bed is... To just start a print and then stop it, then level the bed. Also i use a single sheet of paper, do not fold it or the nozzle will be too far from the bed. Also i recommend using a mirror(ikea mirrors are awesome and cheap), clean it once with soapy water, dry it with paper towels AND NEVER TOUCH IT AGAIN and you will have amazing adhesion without needing to use any tape or glue. It will actually be stuck so hard that you will be able to take it off only after the bed completely cools down. Oh, one more advise. Sometimes the bed is not completely flat. You leveled all the corners but the middle seems to high/too low. In that case just make sure the middle is level and print in the middle only ;)

[@alexmh6131]

If you print in the middle only, your loosing a hell of a lot of build surface/space/plate what have you. Best to get the issue sorted and dial your machine in so it works consistently and as intended

THANK YOU for talking about the paper thing Angus! It confuses so many newbies.

I'm partly to blame 😩 kinda evolved with the hobby

[@BillieRuben]

@@MakersMuse don't feel bad! It's not a blaming thing. Like you said the hobby evolved! You can't be blamed for not doing it differently when other ways were hardly even known! You do great work Angus, always.

[@TheSecurity16]

@@MakersMuse I once got told that the paper method was more accurate than using a feeler gauge. I tried telling this person why it was a flawed method but they insisted they knew better even though the problem they had related to the nozzle height being off.

[@BoldRam]

As a 53yo electronics tech but 3d noob I've been using a 0.12mm / .004" feeler gauge and feeling for the vibration as I move it back and forward a bit and it seems to give me great first layers. I did take a bit to work out in my mind how the adjustments on the bed alter the plate. Now I heard your explanation about it to do with the relationship to the frame it makes a lot more sense. I pictured the bed adjustments almost twisting the bed. Until then I was getting really confused doing a manual level before hitting the auto level button. I have to say I have an Ender 3 v2 Neo and whether it was that I made sure to follow all the instructions for once or I got lucky I've had an awesome experience so far with your's and Chep's help. Thanks heaps from New Zealand 👌🙏

[@grassroots9304]

This was helpful as I absorb all I can prior to purchasing a 3D printer. Re the feeler gauge: as soon as you said something about the leveling w paper I was screaming "feeler gauge". Especially folded paper will give crappy results. FYI: an inexpensive feeler gauge set at most automotive stores as they're used fir several tasks including gapping plugs. That for folks who might have a 3D printer and not mess w automotive stuff. Easily purchasable hopefully nearby w out waiting on shipping.

[@johnsensebe1838]

I think what's happening with the folded paper is that since you're calibrating it cold, the nozzle and bed are both smaller than they will be when printing, where they expand due to heating to roughly make up for the paper-thick gap. It's not "correct", but it's usually close enough to work, and calibrating correctly would mean doing it at print temperature, which would likely lead to burnt fingers.

[@Snagglepuss1952]

yep...sure does, especially with my pork sausage fingers!

[@antalz]

Isn't folding the paper just going to make your problem worse? I always just used a single paper thickness, and I'm more on the side of elephant's footing than warping and detachment. I usually don't mind elephant's foot too much, easy to compensate for with first layer XY compensation and/or a bit of sanding/deburring. You can also chamfer the bottom of the model if possible.

[@nitacawo]

btw you can adjust elephant foot by adjusting initial layer expansion you will get perfect first layer and no elephant foot.

ABS has desirable qualities depending on what you are doing. It solvent welds, sands, and scrapes very nicely.

[@olawlor]

Yes, and I love how nicely you can tap holes in ABS. PLA melts into a blob around the tap if you got too fast, PETG has some crumbs, but ABS looks great. (It's a pain to print though!)

[@nonononononononon5478]

your attitude and knowledge are sooo spot on- - its AWESOME how you still wanna learn-

[@ChucklesMcGee780]

sir ive had my creality ender 3 s1 for 2 weeks and i have learned so much from your channel. you've spared me a lot of headache, and blown my mind many times. i have nearly achieved perfect prints thanks to things i've seen here. THANK YOU

[@MsDemzon]

I see the "ABS is stronger" thing all the time, and it never matches with my experience. Thanks for covering why that is wrong, and pointing to the detailed breakdown of why.

[@FrankBocker]

ABS shines in impact resistance, flexibility, temperature resistance, and strength to weight ratio. PLA for your personal CNC machine or shelf brackets, ABS for a phone case or a drone body. And if someone's selling PLA and ABS for twenty bucks a kilo each, the ABS is like a 25% bigger roll because it's less dense. My opinion might be biased by the amount of effort I've been putting in recently to get set up for and familiar with ABS though. But it's been fairly rewarding.

[@MsDemzon]

@@FrankBocker like I said: I haven't seen that practically. Like he said in the video, there is a large break down in all that. This is one of those too like we see in the personal protection gun community. People say that a .45acp 230gr is better than a 9mm 115gr. Is real world use, there is not enough of a difference to practically see a difference when used. So, sure, the materials numbers may be diffrent, practically, there is not a user difference.

[@Kalvinjj]

@@FrankBocker There's also material creep: from what I recall, ABS isn't as susceptible (or at all) to that effect compared to PLA. So parts under constant compression are better off with ABS.

[@Crits-Crafts]

wait leveling the print bed with a sheet of paper is flawed? Well, thats a pain

[@ForestGramps]

Idk, I feel like he kind of over exaggerated it by folding the paper a ton. From what I understood, the issue comes from the fact that you’re leveling the nozzle to be set at a paper-width too high. So if you use something thin, like a post it note, it would work just fine? Especially if you set the initial z high to be the height of your leveling tool ~.01mm i think

[@TheHMSBros]

@@ForestGramps I do believe this is the case, I use a single layer of paper, and I make it have a decent amount of friction, works pretty well, but not quite perfect

[@Mickice]

It's only flawed in relation to the first layer height of your gcode. If both are equal it is fine.

[@Sidewinder1311]

I see leveling the bed and setting the nozzle height as two different things... So imo it doesn't matter how thick the paper is for leveling.

[@BrunodeSouzaLino]

It isn't. The issue is that you should not fold the paper. Paper of a specific density has a standard thickness. Your bog standard 73g ones are .1mm thick.

[@henninghoefer]

I recently got my first printer and I can't even "level" it across the entire bed - when the four corners are correct, the center is too tight and if the center is correct, the corners are too far away... 😢

[@MakersMuse]

Sadly sounds like it's bowed :(

[@akunog3665]

yes, Bowed. What type of bed is it? I have a glass top that is slightly low in the middle, and putting a few squares of aluminum foil between the glass top and the metal bed I was able to coax it back to flat. However, the warp was very slight (0.1 to 0.2mm). I don't know if you could shim all your corners.. or flip the bed top over and shim the middle. However, likely it will be better to get a flat bed top :/

[@QBziZ]

Flip the bed if possible. You can correct a bowl with leveling screws, but you cannot correct a dome.

[@henninghoefer]

Thanks for all the responses. Printer is a Biqu B1, bed is aluminum with heating and isolation on the bottom and a magnetic sticker on top (for the flexible steel sheet). So flipping is not really an option, but I tried shimming the corners between the magnetic film and the steel sheet and the first layer is still inconsistent. I now ordered a BLTouch, so I (hopefully) can correct for the bend…

[@akunog3665]

@@henninghoefer I have 0 experience with the BLTouch, so I can only wish you luck with it :) After I got my ender 3 the first upgrade I did was to remove the magnetic flexible bed and replace it with a sheet of glass I got at the local window shop. I was able to shim and clip the glass to the aluminum bed. The sheet of glass was very cheap ~$10. Now, getting prints to stick on a smooth glass bed is another challenge all together (but not too bad after a few failures). Hopefully the BLTouch will solve your issue.

[@aschneider93]

Coming from me, a guy with 5 years of CNC machining and milling, 3D printing is a hobby I enjoy. And honestly the last part of the video on leveling helped, because I have used this technique in milling but for some reason never crossed my mind in 3D printing. Typically in CNC we have a tie-down bed that we mill if it needs resurfacing, then we determine the tool heights and machine zeros from the bed with feller gauges. Or in the case of more modern machines, a computer controlled touch feeler. But anyway, thanks for the help!

[@nope638]

RAD. Kudos on the feeler gauge.. After buying a mini milling machine a few years ago, Using the feeler/thin metal strip on my printer was a no brainer….( And Yes, tram the printer!).. Also.. The P.L.A. Vs.ABS bit was spot on.. Good info.

[@vancelanger7749]

I've been "leveling" (tramming) my bed lately using a flashlight. Shine the light behind it, get down low and look across the bed, and move the nozzle down just until you can't see light under it any more. It's crazy easy, almost too easy to screw up, and gives you a near perfect zero point. Also, I really think the first and only mod anyone needs to make to their printer is installing Marlin 2.0 for mesh leveling and babystepping. Seriously, this is pretty much a requirement especially for kit printers. These two features are real game changers and absolutely crucial for getting pornographic first layers

[@humbughumbughumbug]

I've done this too when I was in the field (doing a demo in a class) Just make sure the nozzle is clean and it works nicely

[@stanrogers5613]

Paper still works a treat - provided you have a micrometer (calipers, particularly cheap digital calipers, are, um, a little less than useful) and _consistent_ paper. There's a reason why machinists use paper: it gives a very good non-destructive go/no-go test if you shoot for "just grabs" and no tighter. The key is in knowing what the actual thickness of the paper is and using a single thickness. (Cigarette rolling paper was the traditional stuff. Extremely consistent thickness and a relatively "hard" surface that doesn't deform much. It's a lot less available these days than it used to be in some areas - and I'd suppose that Oz isn't exactly roller-friendly anymore, what with ciggies being, what, thirtyish dollaridoos a pack and climbing? I'm all for nuking smoking, but won't somebody please think of the machinists?)
