sorta hoping one day ill earn a free printer 😂 thanks for the positive feedback!

The most informative video I have found yet on solving my bed leveling issues. If only Anycubic themselves had some tutorials as useful as this.

Installed the spacer mod you outlined, and used a straightedge to "eyeball" level it. I will go back and use a dial indicator later this week, but already the change has netted good results. Thank you

Thank you so much for this, you've no idea how much I appreciate it! Was having all kinds of issues with my kobra 2 max and your guidance helped me a lot.

that's incredibly clever! my kobra max 2 arrives next week, definitely saving your tips. Thanks

oh man this video was so helpful especially the file for the clip! i found a max of 2mm variation! ordered a new print bed hoping its not warped and if it is i know how to fix it thanks to this video.

A new owner supplemental parts list for the spacers, printed parts, depth gage and clip on print, would make a great PDF or even an nice bundle pack. I'd probably spend $20 on a kit that had all the parts you used/listed in order to get the bed leveled out of the box. Super helpful video!

I put all the parts in the step by step videos description found here kzread.info/dash/bejne/l4pto6mmZs-yeMo.htmlsi=tIOrVCzACzoEbjTB you can print the supplemental spacers or just find a spacer(s) that measure 3mm in thickness to add to the Silicon for the middle bed spacers

Thank you :) Incredibly helpful.

Товарищ! Спасибо тебе огромнейшее!!! ❤

you are genius bro

just a word of caution, do not move the bed or head while the machine is switch on.without disabling the steppers 1st. it creates its own electricty and you can blow your board or display pannel.

I also got this issue of shifted layers. According to my observations, these issues happen at quite big distance from build plate (around 20-30 cm), which means the weight of plastic is already sufficient. I reduced all accelerations to 5000 mm/s2, and till now I never got this issue again. Seems that in my case the motor skips the steps when the load of plastic is around 300 g or more, and inertia of build plate + printed model is too high for motor...

Hello, thank you very much for this video and your work on it. I use the same printer, what I saw on yours is the drag chain for the rear cable. Since there are matching end pieces on your drag chain, I wanted to ask if you would make the .stl file available to me. Many greetings from Germany.

check your belt tensions on the bed, make sure they're equal, i was playing with them and found this to be an issue i had

If they allowed you to disable the mesh leveling you would honestly have a way better time. That is my issue right now, my bed is dead flat using your methods and the mesh digs into the bed in certain spots.

👍

Did you make the dial caliber attachment?

That's very hepful video. I bought kobra2max a month ago but I have Z offset issue. Every after autoleveling, I have to calibrate Z offset during printing. (I could find z offset adjustment). Nozzel calibration sensor is at same height with plate but I couldnot find the problem. That's why I couldt printed anything yet. If you now how to tune Z offset not during printing, please share. Also I'm going try silicon spacer and try to calibrate with dial indicator.

I had the exact same symptom, always had to re-calibrate. I think it was to compensate for where on the print bed I was printing various parts at. I have a feeling this is going to solve your problem, I just uploaded a step-by-step guide I filmed while setting up my second Kobra 2.

Seriously, you are a godsend! I have been struggling with this printer to be consistent. You mentioned a FB group, what is the name of the group?

For the layer shifting...fought that for a LONG time. In my case the vref was WAY too high and motor getting too hot. Adjusted that and things got better but still happened occasionally. Player with acceleration and dropped it from 2000 to 900 and set jerk to 10. Have run over 2kg through it and haven't had so much as a single shift on my kobra 2 since. Considering how much more mass your max needs to move on the Y compared to my kobra 2 I have to wonder if too high acceleration might be causing you some shifting.

@mark4jr

Can definitely confirm lowering acceleration does help. the thing is though I have two of these printers and one has never experienced layer shifts the other is prone.

its very hard to do this large bed perfect so many variable like like filament quality dry or not or slicing settings ,room temperature,heated bed temperature nozzle type ,bed leveling.... maybe easy to first lever height set to a bit more and width overlap 15-25% or the motors,frame equal ,not slip the belt

I noticed the cable for bed heat out the back you had a blue 3d printed cable stabilizer. Where did you get it? I would love to print 1 for myself.

Awesome, thank you so much!

Just a question in the slicer is thete gcode to use the bed level mesh? If not can get it to level for each print with g29 after g28 code.

@mark4jr

2 ай бұрын

The start/stop Gcode gives the printer instructions regarding prior to printing and when the print is complete. The firmware of the printer should load the bed level mesh regardless of the gcode, in my testing I do not believe the bed level mesh does anything with or without gcode instruction. The only way ive been able to get consistently good prints is with a manually flattened/leveled bed.

@@mark4jr Weird. What slicer are you using? Just got mine today and set up. Using anycubic slicer and everything seems to be working great although the auto offset applied by the printer was a tad on the aggressive side at -1.19 so I backed off that a tiny amount. It seems to be working flawlessly. Even in " sport" mode I'm getting great prints. Set up my first full helmet to print though so bit nervous about later shifts on that so set it to standard but it's still crazy faster compared to my ender 3 😂

I have problem with bed level in kobra 2 pro but i have no idea how to calibrate it manually because it have only 4 screws without option to install distances

I would think you could probably still apply the silicon spacer mod, if the existing metal spacers are all the same size then you should be good to go. There is another video in the description of this one that is more of a how-to

Any chance you could link the dial indicator mount file? It looks just like my Harbor Freight dial, and it would save me a ton of time.

I put all the links in this more of a how-to video : kzread.info/dash/bejne/l4pto6mmZs-yeMo.html I have both printers dialed in pretty good at this point, letting them completely cool down before each test print was pretty key I think so the first layer went down with a relatively consistent level of heat saturation, also I think making sure everyhing it tight but not crazy tight is pretty important. For that I home the machine so the stepper motors are engaged and give all the moving parts a good wiggle

High Mark thank you for the video. I'm guessing you haven't been printing for very long. You wasted a whole bunch of your time calibrating the bed when it was cold. Secondly it never hurts to calibrate with the build plate off. But more importantly to calibrate with the build plate on. It's critical for beds this size to be preheated for over 30 minutes before doing any calibration as the build plate needs to heat soak. This is why you are having print issues even though your bed you say is level. I've seen deflection at almost 0.2 or more. Which is a full layer height or more. Imo what you did wasn't wrong. You just missed the steps of heat soaking to get more accurate bed level. Sadly it seems these printers both the elegoo Neptune 4 Max and the Cobra 2 max have troubles maintaining their bed mesh. That means we'll have to manually see adjust for large prints every single time

@mark4jr

You have a good point about preheating the bed before leveling. I would recommend doing that and have done that on one of my machines. When I get some time, ill update the video and add that. Cheers!

You fokin demigod ❤️🥵

There is no way the software can compensate, where the sensor it reading and where the nozzle is located are two different heights, they should stuck with the leveling that they used with the kobra max. they should not be shipping this out with a warped heat bed, its a defective product and anycubic needs to fix it.

I had exactly the same problem, but I just sent an email to #anycubic, send the pictures with the gaps under the ruler, they send me a hotbed!!! Here is the reply(Hi there We send you a free new {Heat Bed} to solve the problem. Please fill in your information in the link below so we can send your package to you. Note: The phone number is required, and the address information needs to be specific to the house number. After filling in the address, please reply to me for confirmation.) just filled the information and they send me a brand new one. So if you are having to many problems.... Maybe.... It's not your problem!!!! Meanwhile while you are having issues of bad leveling, slow down the first layer and just go up and down the Z-offset as much as you need to try the best layer as possible. You do lose a lot of time, but after I started to to manual leveling I stoped having warped and pealing layers, and I was printing with a 60º temperature, was able to go down to 50º(saves up a lot of electricity)haven't been printing nor rafts or brims, straight to the bed... For the shift layers I only have problems when I forget at Anycubic slicer to zhop on every retration. Hope it helps
