yeah z offset calibration seems to be a huge bug here. support told me they made an update in auto z calibration but it doesnt seem to work properly. the nozzle touches the bed when calibrating and everything seems fine, but when it prints it just doesnt make a good layer. on my kobra 2 i could manually adjust z and it saves it permanently (until a new auto calibration of course). but when i manually adjust z on kobra 3 it resets before every print because it makes a little calibration every time.
Thanks for your comment ,Sorry to hear you are having issues looks and sounds like many people are having the same problems with the z :-( ,I just started to use the anycubic slicer next software and it done 2 updates 1 for the printer and 1 for the ace not sure what it done but looks like mine is still working ,I had to try as didn't work great with Pteg before I updated ,fingers crossed you get it working right soon ,looks like anycubic are willing to try and help so that's a plus, have you updated and used the new software ?
@@atgbni i am trying various slicers, now i am working with orca and an provided profile from anycubic. i now found out that the rolling bracket under my hotbed seems so be bend a little and the auto calibration is not able to fix the leveling issues. it prints to low on the left side so that it scratches the bed and ruins the layer and to high on the right side. i put some small washers under the bed screws to level it manually and now i got decent first layer. im staying in contact with the support who responses well and innow try to get a new bracket. i am looking forward for new updates either because i think the leveling process is not working properly.
Thanks for your reply :-) .I am happy that Anycubic is trying to help you .I do think we a guinea pigs and beta testers but my Elegoo was the same but got that all working well now and looking back I had fun learning but it didn't feel like that at the time ..
yeah, I wish you could just manually adjust and save it. I do this on my Ender SE after auto leveling because it's never spot on then I don't need to worry about it until I auto level again. I get pretty good adhesion for the most part on my k3 some minor issues. The main problem I have had with it is when trying to use smooth time lapse. the z offset moves up for some reason and I get poor adhesion and failed prints. I can do the same exact print over with smooth time lapse shut off and no issues. Makes no sense its like a bug no reason to raise the z offset for the time lapse no issue with a normal time lapse strange.
It's the eccentric nuts. When you do timelapse, the gantry goes to the top and somewhere during that travel the wheel doesn't make contact on one side or the other and makes the z axis "slip" a little. For me, it's on the right side where there is no motor to drive the leadscrew, and it kind of flops up and down, usually being too high from the bed on that side.
Thanks for watching and your message.For me the issue was a loose eccentric nut that gave a false x offset.but for quickness I replaced the hot end as it did touch the build plate ..I do believe that anycubic have recently updated the software to help with the z offset that many users have had big issues with ?
I'm at my wits end with my kobra 3, first the bed was warped so parts of the printer would stick and others woudn't, support sent me a new one, now the Z-Offset just won't level properly and sits way too high every damn print, I don't even know what to do anymore Thanks for the video tho, sadly my gantry bolts seem to be tight
Thanks for your message and watching my uploads ..I am so sorry that you are having so many problems :-( It must be so frustrating having to wait for the printer then it being faulty ...I would just say have it back anycubic and give me a new one ....I have been lucky with mine so far fingers crossed .But have seen lots of people with issues .If I can help in anyway by seeing how mine is setup any different than yours please let me know .
Make sure you temp is high enough. I've seen this when the head temp was too low. Also make sure to do a bed leveling which should compensate for most all bed warping. I have one of these and truly love the thing! Ohh... And make sure you use new PLA. I've had PLA sitting around for 5 years and even after dehumidifying it, it was causing all kinds of adherence issues. I use a brand new reel from AnyCubic it worked perfectly.
@@kevy1yt Thanks for the help :), I've tried from 200 to 250° for the nozzle and 60 to 70° for the bed, checking the nozzle was clean every time and still same issue, nozzle too high and since the z-offset sets every print I'd have to try to manually compensate every print Also I leveled while Heat soaking and without heat soaking and still nothing The filament came with the printer, it's their new Pantone one, the thing I don't understand is the first 3 prints I made on the new bed (since the first was warped) came out perfect, then it decided to just not print anymore I see the potential and know it's an amazing printer when it works, but I think I'm gonna return mine as I've had nothing but issues
@@EkaitzHonuchPrieto that might not be a bad idea but give them another try. Ask for a replacement. It sounds like your unit might be defective. Their customer support is really good so they’ll probably be happy to replace it. I’ve done maybe 200 hours of printing so far with excellent results. Good luck!
I have the same issues. I printed well the first hours and got no big problems, maybe a little filament tangle, but suddenly the kobra 3 is getting one problem after another. hotend faulty, clogging, massive z offset problems (nice layer on the back side and back left, then bad layers on the front left and especially front right so i got warping from my prints always on front right side). got a new hotend, new hot bed from support but still problems. after installation from the spare parts i made a reset, them the first print went well. i started the SAME print file after that and got problems imediately again …
Hi, this question is off the subject, but where can I get the file for the gingerbread box you were printing? My daughter saw it and fell in love with it. Thanks in advance.
Thanks for your message and taking the time to look at my channel :-) .I make the led lights myself from start to finish I have tried to make a google drive file and will upload the file there ,hope it works as never done it before :-) .So glad your daughter likes them .Please let me know if the link works or not Thanks again. drive.google.com/drive/folders/16eUFLIm7RE-Q4s9A36ldNoeXX3Vxtn1Z?usp=sharing
@@atgbni This worked just great. Thank you. I have a Cobra 3 combo and like it very much. So far, no problems at all after almost 300 hours of printing.
on the forums, there are lots of ideas as to why people are having problems with the z offset. So far I have heard the reason could be a sensor faulty, or software issues, my favorite is the clip on the extruder getting dislodged or move as it is a very basic holder. Lots of others but I haven't seen your reason on the forum so will add it next time it comes up. I've never really had the issue. I also don't do a bed level every print...if it works why fix it.
Thanks again for you message :-) and watching my channel .I am the same if it works it works .I think the issue I had was down to me not paying attention and doing the basic maintenance :-( .It was so strange as it happened straight after I was asked about it I did think my live was hacked lol .But very happy its sorted and working as it was ;-)
@@atgbni it was me that asked, that is soooo strange it happened straight after i said, mines arrived now an the first thing i did after watching this is retighten it all up. But it does line up with what everyone has been saying, i think like you said just basic weekly maintenance should keep it printing perfect! least its sorted now :)
@@MrMunch360 glad you got yours now and you didn't have to wait to long :-) .I have the elegoo as you know so I should have known better I think having the 2 on the same bench working at the same time makes them vibrate a little more so things are going to get a little loose .I did think you were a super network hacker and altered my Z offset remotely lol :-) Thanks again for your comments and views .
Thanks for watching and I am hopefully soon going to add a Google drive with the stl files so they can be download if anyone wanted to but sorry still working on that 😔
Sorry you haven't had much luck with your printer :-( .All I can go on is my experience and I must be lucky well at the moment anyways .I have seen people with issues and also people with none .I hope anycubic help you fast and you get back to printing :-)
i have this printer to and all im having is a problem with the Z offset it keeps changing it self by its self i had it set to 0.75 now its gone to 0.11 then it changes to 0.7 now 0.4 and it knocks over the purge block
Thanks for your message .I am sorry your having problems :-( .I must say I have only had 1 one issue with the z offset and it was the roller as pointed out in this upload .I have seen a few comments about this .But I must be lucky .but I would start from fresh make sure your rollers are clean as sometimes they can get a build up of grease and sometimes i have found some old pla poop on the rails ? don't know how it got there .so clean and tighten then start from fresh with your self level
@atgbni the only problem their is ive only had it 3 days new i did watch the video and checked and 1 was a bit lose but this did not seem to fix it hmm
cobra 3 need manual bed leveling , just lose nut on yhe bed. and level manual . i have issued with first layer and top layer , then i level my bed manually, then auto level. done
