Official Creality CR Touch Auto Leveling Kit, 3D Printers Bed Auto Leveling Sensor Kit for Ender 3/Ender 3 V2/Ender 3 Pro/3 Max/Ender 5/Ender 5 pro/CR-10 with 32 Bit V4.2.2/V4.2.7 Mainboard

After installing this i was finally able to do a full print without any errors or issues. Wasn't the easiest thing to do but I love a good challenge and it was worth the effort.

I finally had the opportunity to install the CR Touch auto-leveling kit onto my Ender 3v2 printer and it was a fairly straightforward process. The most difficult thing about it is getting the right firmware to work with it, and for that I would strongly recommend ditching what Creality offers as it isn't updated regularly and the current version is far out of date and hopping on the Jyers bandwagon like I did. Jyers is outright tailored to things like auto-leveling, filament runout sensors, adjusting the print settings to adapt to bed tilt. Effectively what this does is when used with Jyers it creates a mesh for the bed to determine which points are high and low and adjusts the z-axis accordingly. As far as that goes, I'd say it does a splendid job. I used to have a problem where the middle of my bed was too high, but now prints actually appear on the first layer. I've used this with both glass and magnetic beds and it works splendidly. It works effectively as a replacement for the standard Z-Switch but does have a problem in that it will shift quite a lot and require, in my case at least, at least one of the four adjustment wheels for the print bed to be adjusted every print. I've found a good workaround process that makes this less dramatic, though. My current process for this is: 1: Determine Z-Offset in the center. Don't forget to save. 2: Adjust four corners. Use manual leveling for this first. 3: Create a new mesh for the CR Touch. Again, make sure to save to EEPROM. Make sure to do this for every SD card you use with your printer. After that you'll be ready to print. Overall it's a new plate to juggle in terms of 3D printer maintenance but I'd say it's a welcome addition and definitely worth the money if you have problems with a noticeably unlevel platform for your prints. If you're thinking of replacing your glass sheet, magnetic bed, or heating bed over this, I'd genuinely compare the cost against the CR Touch because it may very well be the cheaper option. If the price isn't substantially lower, like below 10 dollars, just get a CR Touch.

Manually leveling my Ender 3 print bed was a pain, only for many of my prints to fail anyway. The CR Touch was part of a number of upgrades added to my printer. Along with 4.2.7 mainboard and Nebula Smart Kit upgrades I no longer have to manually level the bed before every print. Just one time during the initial setup after the upgrades were installed. This saves so much frustration and has greatly improved the success rate of my prints.

The settup can be a bit complicated when getting the firmware updated, but once that is taken care of and the z offset is nailed down, this is set and forget. This had been a fantastic addition to my printer and I highly recommend it to anyone wanting a more reliable first layer.

While I think it's great for someone to learn the manual level process, this speeds up that process for those who are ready to move on and upgrade their printer! Highly recommend.

This is all I needed to fix my Ender 3's broken heat probe fast.

I have been looking at these for some time, when the opportunity arose I jumped at the chance. The item came neatly boxed and it has essentially everything you need to set it up. This auto leveling kit comes directly from Creality and it fits multiple models. It only took me about 15 minutes from start to finish, to get it physically installed. That being said there are some things that you need to do, specifically a firmware update if your printer didn’t come with a auto leveling sensor. Hence the reason why you would purchase this in the first place. After visiting the manufacturers website, I downloaded the Firmware to the microSD card and uploaded it to the printer. I watched a few videos on YouTube, just to see what others experiences were. Given some of their recommendations I opted to edit the G code, that way the printer will run through the auto leveling procedures every time. I then loaded a file that I’ve been wanting to print for a while and knew it was going to be at least a day and a half to completion. At about 80% the printer threw an error code, stating thermal runaway and went into a halted state. I had to shut the printer off and turn it back on to resume printing, this happened multiple times. I eventually got to the point where I was consistently getting the error every few minutes. I opted to cancel the print and do some research online, there are various things to try but I believe I found one that worked. I decided to do the PID auto tune and that seemed to cure the issue, no problems since then. After updating the firmware in the beginning, it’s possible that it tweaked some of my settings. This is no fault of the auto leveling device itself, the only reason I docked this a star was given the lack of instructions for firmware/trouble shooting. Everything appears to working correctly now - if I had to do it all over again I would still get this item. Try it out - just be prepared to understand it’s limitations and possible trouble shooting needs. P.S.- this was installed on a Ender 3.
