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:
-
Upgraded support algorithm to enhance support detachability and structural diversity.
-
Optimized calculation accuracy for printing time estimation of Creality HI.
-
Improved slicing efficiency when enabling support.
-
Fixed false alerts: “Preset/printer mismatch” and “Device self-checking”.
-
Fixed 5.x presets import failure in 6.x.
-
Added Ctrl/Shift multi-select in object management tree.
-
Smoother multi-device switching in details page.
-
Fixed printer name modification failure in lists.
-
Fixed firmware crash from special characters in files.
-
Fixed Error 2060 and coordinate anomalies in specific scenarios.
-
Optimized LAN stability, resolve device connection failures, transmission errors, empty device lists, and camera freezes.
-
Fixed the wipe tower suspension issue when enabling non-sparse layers.
-
Fixed object exclusion errors with excessive models.
-
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!
logre solucionar el problema ,solo hay que apretar los tornillos con la llave Allen ,en mi caso estaba uno suelto ,los revise todos y desapareció el error.
espero les sirva

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.
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?
You can find the firmware and software here: Creality Software and Firmware Download | Creality Cloud Download Center
hi,
can you help me to download 1.2.3.21 version?
It worked, thanks. 6 prints , without this error
I encountered the same issue repeatedly. When levelling, it would resolve after tapping the heat plate a few times. Recently, it stopped resolving, requiring me to repeat the process 3-5 times. I couldn’t take it anymore, so I removed the heat plate and cut the 5-pin socket on the motherboard underneath, soldering it back in place. It’s been 10 presses without any issues, and I’m very relieved.
Remove bed. Unscrew gently lift and set aside. Wires for strain gauges are on top of bed carrier plate and under bed insulation. You can see them wound up and leaving mark in insulation. Re-route those wires under the bed carrier plate. Plenty of room just be mindful of carrier travel path. Extra wire can be bunched in holes of carrier plate, yet will be under the plate.
While here, check attachment screws for strain gauges. If loose add a drop of Loc-tite and snug.
Set bed back in place, gently snug screws. Then loosen 1/2 turn. Now heat bed to 80c for 20-30 minutes. While hot snug, dont over tighten just snug bed screws.
Re-run all calibrations.
Just got zapped with this. Seems like one of the simple fixes is the one mentioned. Pull the bed, unseat the connector of the cable to the sensors for leveling, reseat. Put the bed back on. Run self-tests. It passed self tests and it wasn’t prior to the re-seat.
@CREALITY, WHY do you see the need to hot-glue everything in creation down? Even the bed insulation to the platen?

I’ve had my 2, E3V3Plus printers since Aug 2024. No major issues.
Today, however, I send a print job to one. I do monitor the print via its little camera. I noticed a little blob on the corner of the print and that corner lifted up. That never happens.
So I went to the printer, cleared the issue, cleaned the bed, I sent the print job, which I always have checked off, “calibration”. yeah, redundant, but keeps thing printing nicely.
As it started to do the bed leveling, up pops this CL2529 error. In reading the error, I focused on the word, “interfering”. To me, that wasn’t a software issue, but rather something “related” to sensing.
I raised the gantry to get a better look at the nozzle, since that’s what does the bed leveling by touching it.
What I noticed is that there was some gummed-up plastic around the nozzle and a thing film seems to be right across the tip. Knowing that the sensor must sense the bed/plate (capacitance) I decided to clean off the nozzle and tip. Once it was clean I sent the printer through it’s self test for bed leveling.
It performed it without issue and now, prints just work.
So check the nozzle to make sure it’s 100% clean, especially the tip.
By the way, since buying these printers, I only allowed firmware 1.2.3.21 to be on the machines and refused to update from there, so as to avoid any problems that updates CAN and often DO cause.
Also, I’m still using Creality Print 5.1.14. I did try an update but hated it. So I stick with what works. I get gorgeous prints, so why mess with a good thing?
Hope that helps.
