ComgrowOfficial Creality CR Touch Auto Bed Leveling Sensor Kit with 32 Bit V4.2.2 / V4.2.7 Mainboard and Metal Push Pin for Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5 Pro/Ender 5/CR-10 3D Printer

No se si pase a otros pero el firmware bajado de creality hizo ilegible la pantalla y muchos problemas para leer las tarjetas de memoria. Mi equipo es una ender 3 pro con tarjeta madre v422 el sensor funciona pero la interface entre humano e impresora deja we funcionar. ahora estoy en si un cambio de tarjeta madre a la v27 resuelve los problemas o mejor tiro la impresora.

I level the bed manually every 5 or 6 prints. It gets out of level a little bit on its own. I run the auto leveler on my ender 3 v2 before every print. It checks 17 places on the bed. A 4 x 4 grid plus center. I have had zero adhesion or print issues ever since. For the ender 3, it is a simple installation. Update the fw, and wire it up. It takes the place of your Z stop, so you won't need that anymore. If you don't know how it works, it measures all over the print bed as I mentioned earlier and then it makes micro adjustments to the z height as it prints according to the map it generates. I couldn't be happier with it. Maybe it could be a little faster, but really it is so worth the upgrade.

Buyer beware - device seems to be working as advertised (no mechanical issues). However, the instructions and firmware for Ender Pro 5 were insufficient.The first part of the instructions written on the included pamphlet were accurate. This included mounting the sensor to my Ender Pro 5 and attaching the cabling. Then came the part of flashing the firmware.Creality needs a drastic improvement in their Quality Assurance process to make sure the instructions match what is available online AND the correct versions of firmware are posted and labeled very clearly. After flashing the firmware, the printed instructions no longer matched the menu options displayed on the Ender Pro 5. Thus began the several hours of research for additional resources to move forward.It wasn't until we found a reference on the Creality forums and paired that with a resource of firmware files posted on Reddit that I was able to flash the firmware to a version that restored the menu and allow the Ender Pro to function properly.All-in, spent at least 6 hours on this minor upgrade. I certainly understand the complexity of managing instructions for a device that could be used on multiple models. However, that is the responsibility of the manufacturer and they should not be rely on the user community to provide the support/instruction.Will be interesting to see how this works long-term. If it saves any time.So far, big investment up front with no tangible benefit.

I had a perfectly good 3d printer before following the directions with this add on hardware. I thought it would make my life easier not having to level manually. Do not buy into the Creality fanboys raving about this junk. The firmware mucked up my printer so now it refuses to print from SD card and the only way I can print is through USB. Tried to revert back to the original firmware and remove this junk but it won't read the SD card to install the original firmware so now I'm stuck with an almost useless paper weight disguised as a 3d printer. Thanks for wasting my time and money.

I bought my Ender 3v2 with this upgrade but set it up initially without it as recommended to ensure the machine was functioning properly before adding it and boy am I glad I did. I had 3 consecutive solid prints mind you these were my first prints ever and everything from the wall smoothness to 1st layer thickness and adhesion seemed spot on. After the confidence boost of setting up my own printer and 3 successful prints I figured adding the auto leveler would be easy and the installation process itself was actually super simple especially with the help of YouTube. I had the auto leveler firmware running correctly and it would preform the 9 point level mesh before every print. I thought I was good to go but this is when the problems started. My 1st print with the auto leveler was so far away from the bed that the 1st layer didn't adhere at all and I had to cancel almost immediately. Ok maybe my bed wasn't leveled correctly which I thought was the whole point of the auto leveler but none the less I broke out a piece of paper and got to it. After ensuring the hot end was the same distance from the bed as before, I tried again but same result. I tried uninstalling and reinstalling the firmware didn't work, double checked the mounting bracket and connections on both the mother board and on the leveler all good, tried messing with the z offset but only once I reached -1.85 which seems crazy high did the hot end even seem to be close. After a day or two of messing with it the only way I could get a decent 1st layer was to tighten the level springs before the 9 point mesh started and then having to loosen them as the 1st layer started with the -1.85 z off set still on and on the next print would have to remember to re tighten/loosen the bed. This trial and error process also resulted in a couple of 1st layers that were so smooshed, that I'm still trying to get filament off of the original glass bed and purchased two more magnetic beds to hopefully avoid this in the future. As you can see this just drastically increased the time and issues with my prints so I decided to send the auto leveler back. This may not be everyone's experience but I've even come across a few youtubers who have had the exact same issue with the exact same machine. I would recommend just manually leveling the bed and maybe upgrading the springs.
