FINALLY! Someone who says more negative number to express moving the nozzle close to the bed, rather than larger or smaller number. I never felt it safe to assume that the person speaking meant smaller when the number goes more negative. Thanks DrVax!

[@AustinKincade]

Thank you SO MUCH! I've been fiddling around for over a week trying to figure out what was going on! It makes so much sense now! Every time I'd gert it level after the probe, it would look so much higher, but after adjusting the Z offset, the first layer looks awesome! You're amazing! Thank you!

[@FrankTank7777]

Thank you so much for this. When I just started 3d printing, everybody tells you how to level your bed etc. and then you should just be able to print. Not true, it took me a while to figure out that you also need to make sure your z offset is correct. Even the official documentation (and video) for my Creality CR10 Smart Pro mentioned everything (up to auto bed level) but nothing about the z offset. So of course being the tweakhead that I am I started fiddling with this value and of course nothing worked as expected after that. Long hours of frustration was had before coming across this information. So I hope any new person starting out with 3d printing watches this video, will save serious pain and frustration, and also possibly stop you from quitting. So long and short of it, I wish I saw this video when I just started out, but it was a nice refresher to help re-calibrate my printer after getting a new head. Now at least I am sure what is "up" and what is "down" with adjusting the z offset.

[@universalgenie]

this video is awesome for me. It gave me the missing hint to get maximum accuracy with the autolevel function of my printer. I am using the Creality CR-6 SE with Autolevel Function without additional sensor. This works very fine but is has a constant temperature for the nozzle and the bed which cant be changed by the user. With the built in Leveling Function it only uses 120°C at the Nozzle and ZERO at the printing bed. I added the two lines of G-Code at the startup procedure in cura as you showed in your video and my first layer test comes out much better. THANKS DR VAX!!

This guy is the perfect presenter

[@soggynode]

Probably the best explanation of the Z Offset I've yet to watch. Good job all around. I am a bit curious about the second G28 inserted after the G29. I haven't seen that second G28 before. Time to go do some research it would seem :)

[@MakeWithTech]

The second G28 is probably not necessary. It just re-homes the printer so they slicer will start from a know position. Once again probably not necessary but does not hurt.

[@AkiraFurball]

@@MakeWithTech G28 disables auto-bed levelling unless the firmware has been configured to not do so.. if you add a second G28 after the g29 marlin will not apply auto-bed levelling on some printers and you would be effectively relying on the manual level of the bed only.. It is completely unnecessary in any case, the auto-bed level IS a homing command as such, it exits with marlin knowing exactly where the nozzle is located as indicated by the x/y/z values NOT flashing on the LCD. It is bad practice at best, and for some people it will result in them not being able to use ABL at all if they add this command to startup GCode. From the Marlin G28 documentation.. Homing is required before G29, M48, and some other procedures. If homing is needed the LCD will blink the X Y Z indicators. G28 disables bed leveling. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28.

[@MakeWithTech]

You are correct the second G28 is a mistake. Thanks for the info.

[@AkiraFurball]

@@MakeWithTech not sure if you can edit descriptions of videos on tube, dont upload very often, if you can might be a good idea to add a note to that effect.. I am just starting in 3d printing and have used a lot of the info you are sharing and very grateful for it, I am now at a stage where bed level is no longer a mystery but without watching you ever know if you missed something, but this time i was able to spot a mistake, a couple of weeks ago I might have made the issue worse ;)

[@NinjaLifeCrisis]

Thanks. I had this reversed in my head. I was about to buy a new printer... :) Now I need to workout auto bed levelling.

[@kb3cxe]

Thank you for a most informative video. How does adjusting the Z offset effect the overall accuracy of the print height? I need accuracy in dimensions as well as good adhesion. Thank you for your help.

[@Erowens98]

Ive noticed that if Z is too close to the bed but not so close that the extruder skips steps, something that can happen is that the tension of the nozzle moving over the previous rows of filament can cause it to peel off the bed. So bad adhesion can occur if Z is too high, or too low.

[@danaolson2871]

Nice zero tools method. If you have a few dollars to spare, I recommend a cheap digital calipers. Peel up the single layer and measure it with the calipers. Make adjustment to Z offset to get exactly the thickness specified by your slicer. I also like to set my Z offset in increments of full single steps of the Z axis step motor. This avoids having the step motor relying on micro steps, as these are less accurate than full steps.

[@MakeWithTech]

Thanks for sharing this approach.

[@GeirAtleStorhaug]

Even when using manual mesh bed leveling you need to use Z-Offset to adjust the actual distance between the nozzle and the bed.

[@MakeWithTech]

Correct

[@blooskyy7]

Beautifully explained, thanks for sharing

[@jmwadding]

So like many others who follow you I'm a noob. I have my bed dialled in nice and sweet for PLA. 50 deg C on the bed. I don't have an an ABL system. I've only printed PLA so far. I'm contemplating doing some ABS work so the bed is going to be "hot". I'm going to assume the bed is going to expand a bit. (How much I don't know). Can I use Z-offset in Cura for example to compensate for this based on filament type and back the extruder height off automatically to match the PLA gap. I have a dial indicator so I can work out the difference in the gap between the bed at 50 deg C and 105 deg C. From poking around in Cura I think this is possible. But I may be asking for a bit too much though of Cura 😊

[@johnm.gerard1718]

also doing the Z offset in CURA allows one to do this on a print by print, filament by filament bases. I thing my Nozzle is to low as one cause of many useing the Amazon Basic filament. I am getting warping in the Front Right. It is so bad that the Print stays stuck to the bed but it is pulling the Buildtak sheet right off the Bed. And you know how stong the magnets are on a Buildtak Flexplat system bery strong. So there must be a tone of force applyed to pull the sheet off the bed. But not the print itself. The print is perfectly stuck to the aluminum Flex sheet. I use the Anti Warping Plug in in Cura 5.0. Try it just on the corners of your print.Also I have tried a Brim which also works well.

[@richardsimmons6470]

Great Video - as usual thanks Just a hint If you have an AnyCubic Kobra Neo there is a setting tool in the kit that allows you to adjust the level sensor to the nozzle. This is not mentioned in the instructions - i guess that all Kobras MAY need this instruction to be carried out - Its an Anycubic Video

[@AndrewAHayes]

I fitted a BL Touch to my Ender 3 and then a few months later I added a glass print surface, my friend was having trouble with his BL Touch so I removed mine so he could use it to see if his sensor was faulty or the code, whilst I did not have the sensor fitted I noticed my prints were just as good on the glass bed as they were with it fitted even my large surface area prints, I haven't bothered putting it back on I am saving it for a Hypercube Evolution build I am planning as I am going to use PEI bed on that printer

[@MakeWithTech]

Ender printers do a very good job of holding level. If you have a glass print surface than the underlying surface will be very flat. The combination of these two factors makes a ABL less critical.

[@DarrenMalin]

thank you , this has been driving me nuts

[@deonholt]

Thank you so much. And now I also know and understand a little bit better. Initially I thought that "0" (zero) is when the nozzle touches the bed. I understand now that the bigger the negative the closer the nozzle is to the bed. But, it doesn't make sense. What is the -2.2 (for example) a measure off?

[@jimmym2719]

[@bgm-1961]

As a newbie to FDM printing, this is exactly what I needed. So, thanks! I learned that my logic was making a drastically wrong assumption. I had assumed that the Z-Offset was merely the height which the nozzle needed to be above the bed, for the first layer. After all, I reasoned that if the first layer was set at .1mm, then that would be the height at which the nozzle would need to start laying down the filament (or in my mind, the Z Offset). But that's not the case at all, is it? Which leads to a question... So let's say I have the Z Offset set to .2mm, yet the first layer height is to be .1mm... well now I'm confused. Does that mean that the nozzle will actually be .3mm above teh bed to lay down the initial .1mm high layer????

[@lorlimann]

Alright you people, I came up with a foolproof method for getting the perfect z-offset in (about) 4 steps. You will need a pair of Vernier Calipers or, even better, a micrometer. 0.) Make sure you don't have any z-axis binding. It is important to have a printer that is maintained well. 1.) Get the bed as level as possible (I do this with the "assistive tramming" feature in Marlin software). 2.) Get the z-offset roughly right. It doesn't have to be on point, too close is probably better than too far at this point. 3.) Now print a cylinder that has a height of 5 mm (I use a diameter of 25 mm at a layer height of 0.2 mm). 4.) Measure the thickness of the cylinder, and adjust the z-offset accordingly. For example, if you measure a thickness of 4.87 mm, change your z-offset by 0.13 mm upwards. If you measure 5.08 mm, change it 0.08 mm downwards. 5.) Adjust the flow rate of the initial layer until it is looking fine to you. (this step may be optional for you). I found that with this method, I get my prints to be way more accurate in the z-direction, which is known to be the most tedious to get right. I also almost completely remove the elephant foot effect this way. I urge you to try this out and let me know how it works for you :)

[@twistedhairball]

I've got a strange one at the moment. I have an ender 3 pro and use a bltouch. I have my bed level to 0.2mm variance. However when I print I get some areas where the nozzel scrapes the surface pretty much, and some where its simply laying filament on the bed and not affixed at all. I have checked pretty much everything I can think of. My Z gantry is straight and level, my bed isn't warped or twisted, as I said my bed is level to a relatively high degree, my Extruder hotend is square and true, my bltouch offset is precise, my z offset is also perfect in most areas. I could go on, but I can't work out why it's doing it. Any ideas? Also thanks for all the great videos!!! They're very well delivered, and produced.

[@MakeWithTech]

Do you have a G28 in your slicer begin print gcode? Have you updated your firmware to include ABL support? Is your z axis rod loose? When you manually level you print bed with ABL off does your printer work properly? All things to check.

[@twistedhairball]

@@MakeWithTech Hi DrVax and thanks for the reply, yes I'm running ABL in my firmware. My standard order of operation is, G28, G29, then I manually run a bed level mesh in octiprint, all with the bed heated at 60*. Regarding the Z rod, no it's straight and securely mounted to the stepper. I haven't tried to manually level the bed and run a print, but I will tomorrow {23:00 here in the UK :)} should I disable ABL first, I wouldn't imagine it would need to be commented out unless I ran a G29...

Noob and beginner here. Working with the mega zero, and in the machine settings for cura 4.5 how do I adjust the z to get the right height? I don't have a auto bed leveler, still watching the video

[@THEFIFTHDIMENTION]

If I set my z to 0 after moving the nozzle as close as possible and my cura settings are initial layer .3 and after that .12. Wouldn’t it be better since my z offset is true 0?

[@MakeWithTech]

The z offset calibrates the distance from your ABL probe and the print bed. If you want to set it at zero you will have to adjust the position of the probe.

[@mauriciobremer]

I've been thinking, what's the point on the auto level routine if the Z-axis won't move until the layers are finished (2.5 axis). I get you map the bed, but the printer can't do anything with it.

[@MakeWithTech]

The firmware will micro adjust the z axis based on the save probe values.

[@ManuelRochaSA]

Hi there, can you similar toturial for ender3 v2 will be nice,thanks

[@lawrenceshraybman621]

Hello I have Biqu b1 and I don't have ABL. I'm running into issues with the printer cutting and rounding some sharp corners but other sharp corners it prints clean. I'm pretty sure my bed is leveled but I do think the nozzle drags on the print more than I would like. I don't wanna compensate for this by adjusting the wrong setting or the first setting I see that may be the answer or can make things worse. Can you suggest what you think it might be?

[@keithpetrino]

i just thought the z-offset referred to the amount the printer had to compensate for a higher print bed. So if the printer thought it was at 5mm high and the z-offset was -0.2mm, then the actual distance from the bed was 4.8mm. Then the printer would have to move up an additional 0.2mm to reach 5mm.

Great vid! Z offset has been one of those things I thought I had a good understanding of but now better reinforced because I watched this. Quick question, the Ender 5 Plus has an option to turn on/off auto-leveling in the menu. Is that similar to adding/removing G29 in the gcode? Still new to 3D printing and learning all I can.

[@MakeWithTech]

I do not have an Ender 5 plus but my guess is that this option disables the use of the bed leveling data collected by the probe in the firmware. The G29 tells the printer to collect probe data. Then during the print the probe data is added/subtracted from the z heights in the gcode to obtain an optimal height. If you do not have a g29 in your start gcode the printing will use the data last collected. This might be our if date. This menu option probably just disables adding/subtracting the data.

Do not add the second G28. I have recently learned that due to a bug in Marlin this will lead in inaccurate Z positions. Is the G29 executing?

I cannot communicate directly with my machine from my computer at all whenever I plug in a USB cable and train find my printer I can't even get to the point where I find my printer because what I'm seeing is the screen and the cr-10 light up as a result of plugging it in. Now the machine is turned off I know it's not supposed to light up I know it's not supposed to be getting power from that USB cable yet it is I cannot get any support through Amazon it's a big castle I don't know what to do what would you do would you replace any specific components what would you do if you were faced with this I really need to be able to do Direct Communications. And I'm not talking about setting up an Arduino or a Raspberry Pi or anyting else that's third-party I'm talking about a basic functionality of the machine do you have any insight into this?

Having the same issue with my V2, There is some driver you should use that comes on the SD card (CH340) but really no good instructions anywhere on how to use it and the manual dont say anything about the USB connection and the drivers at all, just how to print from the SD. Also the homepage for the CH340 driver including general information is all in chinese. With USB you are all on your own appearently. Someone said that u have to try all the USB ports as only one of them will work and things like that. Its clearly not plug and play. When plugged in however on my machine it also powers the LCD and the heatbreak fan spins slowly even with the machine off and appearently from what i read somewhere this is normal behaviour.

@@johnpekkala6941 thank you for this info I have tried to install the drivers from the provided Drive I also downloaded the latest and none of them will install on the USB bus do I have to go through every instance of USB to try and install them is that what you're saying?

[@johnpekkala6941]

@@ClownWhisper Yes. I have not tried it yet myself but hopefully this might do something. I have no experience whstsoever with these strange control chips. Only I know is all these printers run on some variant of Arduino hardware(that I also never have used otherwise before). Would however be really nice getting that USB port working even though I can fully operate the machine using the SD card including running some hand coded G code macros for things like jogging and bed leveling cycles and also pre heating the nozzle and bed individually.

@@johnpekkala6941 I tried it for hours today and nothing will install you can right-click on an INF file and install it that way even doing that and searching the computer for updated drivers will do nothing I am so done with this bullshit. I'm sick of buying shit and have it not work as it's intended to. I mean I can continue to 3D print until the damn card what wears out I guess but I really wanted to get it communicating so I could move to controlling things for my computer when needed. I get no support from creality they won't even return my emails

Wait...this isn't the Dr. Vax channel...?????

It is with a new name. Same DrVax now with a channel name of MakeWithTech.

[@ramtek2702]

No CC, plus, it's impossible to use a printed specimen to set your Z offset if your printer won't print because it needs the Z offset to be re-set. DUH!!

[@ClownWhisper]

This actually makes no sense if you think about it if you get a perfect manual bed level you shouldn't have to even use an offset.

[@ARMYStrongHOOAH17]

Well, it's been a year since you've posted this nonsense, so hopefully, in that year, you have expanded your knowledge. But just in case you haven't, and also for anyone who may be led astray by this misinformation, let me add a correction. Bed leveling is not the same as tramming, or setting z offset. Bed leveling, as the name implies, simply makes sure the bed is the same distance from the nozzle at all points. A perfectly leveled bed can still be too far or too close to the nozzle. Even leveling the bed with a sheet of paper, or a 0.1mm shim you can still find your print is not adhering due to poor z offset. The reasons for this are many, but more or less irrelevant. After leveling your bed you must then start a print and manually adjust the Z-offset until you see the results you are looking for, just as he did in the video, and then save the settings so that you don't have to do this every single print, even though it doesn't hurt to check it every print. This is very similar to the difference between accuracy and precision. In shooting, accuracy refers to the grouping of your shots, ie. how close each shot is to the last. Is your shot placement repeatable. This is bed leveling. Precision, on the other hand, refers to the actual location of your shot. If you aimed for bullseye, did it hit bullseye. This is Z-Offset. Just because you can shoot accurately, getting all your shots into a grouping the size of a dime, does not mean you are shooting precisely, hitting exactly where you expect to hit. Hope this helps.

Not to be "that guy" but there are big differences between "to," "two" and "too." A "Doctor" may want to learn the difference before offering written ideas to the general public. I realize it's not my credibility at stake, however, and everyone has their own standards.

[@MobileDecay]

A lot of people know the difference and make the same mistake. I do it constantly. It happens.

[@michaelmusgrove1357]

@@MobileDecay I try not to constantly make the same mistakes when I know I've made one. Especially such a simple one that impacts one's credibility. If someone's incapable of using their native language correctly, then where else do they cut corners?
