Error CL2529 sidelining my Ender 3 V3 Plus

Well as luck would have it, CL2529 came back on my 3v3 PLUS. Based on my previous career, this could be to do with Z-axis Strain Gauges/Control Circuit Board tolerances impacted by tighter windows built into newer Firmware and Creality Print Versions 6.0 and up or vice versa. I don’t have the equipment to test my theory, but I base this on my previous experience with sensor tolerances and updated FW/SW on equipment I worked with in the past. In the end the solution could be one of two ways. Roll FW back to 1.2.3.21 and use Creality Print 5,0 or get new Strain Gauges (4) and possibly new control circuit board (1) which could have the tighter tolerances accepted by newer FW/Creality 6.0 but no guarantee. Final fix needs to come from Creality but I don’t see that happening unless you contact them directly. This has been very frustrating.

Я менял прошивки на разные но это не помогло, и я вспомнил что я делал самое последнее на принтере. А это, менял высоты оси z из за перехода с petg на pla. В итоге запустил тестовый кораблик без калибровки, при печати убрал значение высоты оси z на 0. И принтер стал работать. Даже после этого прошёл калибровку. Сейчас прошивка стоит 1.2.3.23 печать и калибровку проходит. Но пока непонятно что с качеством печати, как будто она стала хуже.

Along with all of you I keep encountering CL2529 error. It first started soon after FW upgrade 1.2.3.23 along with Creality Print V6.0.3.1591 back in early Feb 2025. Since then, there have been a few Creality 6.0.x.x.xxxx SW upgrades available, none resolving CL2529. Yesterday I noticed Creality released SW V6.1.0.2041, so I took a chance downloaded and updated to the latest. I also reseated all four Strain Gauge Sensor connectors on the control board which sits under the Hot Bed Plate. I also reseated the main power connector to the circuit board. Since it’s also been recommended, I didn’t over tighten the four hex screws that mount the hot bed plate to the hot bed base. I went a step further and reset to default my 3V3Plus (aka factory default). Before printing a test, I also ran Self Check, it completed this time without errors. Printed a few files and did not encounter any CL2529 errors. The V6.1.0.2041 release notes mention a few things I found interesting, not sure if ITEM#10 refers to anomalies related to CL2529 or the reseating connectors did the trick. My 3v3lus is now on day 2 of printing without any errors, at least for now.

V6.1.0.2041 Software Update Notes:

  1. Upgraded support algorithm to enhance support detachability and structural diversity.

  2. Optimized calculation accuracy for printing time estimation of Creality HI.

  3. Improved slicing efficiency when enabling support.

  4. Fixed false alerts: “Preset/printer mismatch” and “Device self-checking”.

  5. Fixed 5.x presets import failure in 6.x.

  6. Added Ctrl/Shift multi-select in object management tree.

  7. Smoother multi-device switching in details page.

  8. Fixed printer name modification failure in lists.

  9. Fixed firmware crash from special characters in files.

  10. Fixed Error 2060 and coordinate anomalies in specific scenarios.

  11. Optimized LAN stability, resolve device connection failures, transmission errors, empty device lists, and camera freezes.

  12. Fixed the wipe tower suspension issue when enabling non-sparse layers.

  13. Fixed object exclusion errors with excessive models.

  14. Fixed MacOS compatibility & UI issues.

Any Guidance how to do this and downgrade?

Hi guys, I stepped into this issue myself. first Creality printer, although we have three other make printers.
Can someone please share the process of downgrading it and not getting this error?
Appreciate any guidance!

I managed to solve the problem by simply tightening the screws with the Allen wrench. In my case, one was loose. I checked them all and the error disappeared.

I hope this helps.

Hello Juan_Cristobal_Carmo and welcome,

Thank you for your suggestion.

Cheers.

Hi I bought a v3 Plus on March 17. After a few days I got the famous CL2529 error.
I followed all topics and all Youtube movies about this, even tighten the screws of almost everything.
Tried homing the Z-axis, did selftest also several times. Use firmware 1.2.3.21 and Creality Print 6.1.0.2024.
Still got this error again and again. Sometimes when I’m lucky it will print an item.
How can I resolve this forever???

I had the same
what fixed it;
power off
remove the bed
disconnect all 4 sensors
reconnect all 4 sensors
reinstall the bed
run bed levelling again

Ho avuto lo stesso problema, per ora ho ripristinato la stampante e Allenata o le 4 viti sotto il letto di stampa, quelle che tengono il perno sul sensore e mi ha fatto la calibrazione. Ma credo si ripresenterà…
Ci sono novità?

Hi friend, could you tell me how to reinstall a previous version? I can’t find the firmware on the website.

Hi, could you tell me where I can get that firmware version?
