SOLVED! As suspected, shifting and alignment issues were caused by a faulty mainboard that is very susceptible to heat soak. The Creality fan setup is also set as an intake fan but it’s intaking into a closed off area with no venting (pressurized zone of warm air).

I haven’t found anyone else with this issue however so it leaves me to believe that this is being caused by a faulty mainboard as all XYZ stepper drivers start acting strange at the same time.. only after the board heats up after an hour of use approximately.

Band-aid fix to verify this was the issue. I unbolted the shroud around the mainboard area to allow venting (yes the fan is operational) but now this allows the air to escape more efficiently from the tiny fan.

And, I was finally able to get stable printing for the entire job, flawless with no hiccups.

Thank! I have been struggling with what seem to be the same issues.  I will give your solution a try.

I have only had the printer for a few days and now have growing concerns after reading this thread. I wonder how many printers are being affect by this issue? I have about 80 hours of failed prints and 20 hours of research the issue. Thanks again for your efforts!

Did you ever get a response from warranty or after sales?

I received my Ender 3 V2 and have been having this same problem as well.  Small prints work with no issue, but large prints (more than 4-5hrs) are plagued with layer shifts.  I wanted to chime in so the volume of the problem could get documented.  I’ll try the solution posted by @brodygoble above to see if it solves the problem.

@dzlqw4 they did send me tracking for a replacement mainboard but I have yet to see it. I believe it is being shipped from China and unfortunately I can’t seem to get the tracking number to work.

Let us know if opening up the mainboard area to further ventilate helps the issue, it really is unfortunate. I was able to get back printing but occasionally now I am starting to get the erratic behavior again as if this mainboard is becoming weaker and weaker or more susceptible to the heat. Last night it happened again where the printer started pressing “enter” on whichever screen it was on (all on it’s own) while some strange layer shift was happening. It ended up stopping the print itself. 

I then waited for 3 hours and started the print over and was able to get it done before the mainboard heat soaked. Simply was a case of trying to do a few prints back to back that tipped it over the edge.

To further add, I’ve just checked the provided tracking for the mainboard (first warranty tracking was for the bowden tube fittings in which the tracking provided by Creality was incorrect and I haven’t received those replacements) and the mainboard tracking number says it was delivered 11 days ago to Germany. So in short, they have provided me with someone else’s tracking info most likely as I’m in Canada.

At this point, I wish I would have purchased a printer from a different company.. painful. To the point where I’m starting to wonder if this is intentional of Creality to try and drag the process out and then finally provide a tracking number that isn’t even correct to further delay it in hopes that the customer will just give up. I mean, it’s happened with both of my warranty claims now!

I got my Ender 3 V2 earlier this week as well and I have been dealing with this issue as well. I tried everything I could find but the problem persists. I haven’t tried opening the mainboard enclosure yet.

Try it before wasting any more time rebuilding it and going over it countless times like I did haha. Must be a bad batch of stepper drivers or something to do with the mainboard. I’m hoping the replacement mainboard arrives soon and I can update with results.

I’ve got my ender 3 v2 last week and when I try to print larger objects I got layer shifts. Every time a layer shift happens there’s also a noise like a tick. I’ve tried to lower the vref on the controllers but nothing works.

 

Now going to try to print with an open case to see if that resolves the problem.

Hello,

I received my printer few weeks ago and so far I made only small prints. In the last days I’m trying to print bigger objects and I’m facing the same issue 🙁

I’ll try to open the case as well, and see what happens! I’m also thinking to put the printer inside the Ikea Lack hack enclosure…I guess it would be a bad idea with this issue ? 

 

(my board is the 4.2.2, not sure if every Ender 3 v2 has the same board)

Same here just received mine, also layer shifting issues. It seems strange, had some layer shifts after printing a couple of xyz cubes after each other, then next morning with a “cold” printer, the first print was successfull, 2nd again layer shift, 3rd layer shifting, 4th I opened the mainboard, again succesfull. Currently, printing more to see if this is the temporary solution. Will contact the seller tomorrow.

Please, keep me posted on your solutions.

Okay opened the cover and at this moment still no shifting where normally I had several layers already shifted. Going to mail the shop tomorrow to see if they want to do anything about it. But it’s a lot easier when you now where the problem is! Thanks

Tried with the case opened and was going ok for about 3hrs, when suddenly stopped printing (lost connection to OctoPrint for some reason!) and couldn’t resume it! Not sure if related to overheating of the mainboard. So lost time and filament! I’ll try again.

After a couple of prints with the mainboard open, it is working fine now. See picture.

Will contact the seller.
