- Anycubic Kobra 3 Z offset issues .After I had a Z offset problem on the first layer with my last print I needed to see what the cause was ,I found in my case it was a loose roller on the gantry so needed to tighten the eccentric nut to tighten the print head to the frame . Fix for me but I know people have different problems and issues :-(
Thanks for watching
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.
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 .
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.

@@atgbni I got to your Google Drive, but it asked me for access. I did and it sent an email to you to grant me access.
@@wallylewicki3022 I have returned the email and given access all new to me so hope its worked :-) .I will add more stl if you want
@@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.
@@wallylewicki3022 Glad it worked ok :-) I am very happy with the kobra 3 as well, just need to do some maintenance now and then ..
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 …
I just cannot print at all with the printer. Frist the belt on the gantry snaps in less than an hour of use. Then the bed can no longer level anymore.
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
