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

Bought this to add an upgrade to my Ender 3 3D printer. The install went great and love the additional feature of bed leveling. I had no issues.

One of the many needed upgrades to the Ender 3. Works amazingly well makes bed leveling a breeze. Great value for the price.

Works as advertised. Easy to install.

I had previously upgraded my Creality Ender 3 Pro to the 4.2.7 control board so I already knew how to open up the control bottom plate. As a result of that experience and by watching several on-line videos about the CR Touch installation I found the physical installation of the CR Touch to be quite easy. Trouble begins soon after. I downloaded the correct firmware for the BLTouch (yes even though it's a CR Touch) and it loaded right up on the printer but I noticed Chinese characters on the bottom of the Info screen and fully Chinese on every other screen. This is a 2 year old printer so I have the original small display not the touch screen display. You have to press the button from the Info screen and scroll down to the next to last line and press to reveal the other language choices. After that, the screens don't agree with the small instruction booklet that came with the kit or it's bigger on-line version. So it takes some effort to find the various items that you'll need to access in order to calibrate the CR Touch. After alignment my initial impression of the performance is excellent. Remember to add the G29 command to your slicer and the printer will do a bed leveling prior to every print. It seems to work very well based on my 2 day experience. Sadly, the firmware regularly crashes. You know it crashed because you'll see some Chinese characters on the display. After a crash it forgets the language and it forgets the Z Offset that you entered. You will have to redo these two items. On-line research led me to the Marlin Firmware site where you can download their version of the firmware. You have to register on the site. They request a donation but I understand that you can enter zero. There are some minor differences between this firmware and the Creality firmware but I've been using it for another whole day and it has not crashed. When you use this new firmware or probably the Creality firmware as well, you must try the load filament feature. Sit down and enjoy.

Probably the best upgrade for an Ender 3 Pro that you can make. I avoided getting one for a couple of years because my printer was working "well enough" and I didn't want to disturb it. Prints in most areas of the bed would be fine, but there were a few spots where I always seemed to have problems. Obviously the bed was warped, but it usually wasn't much of a problem. Eventually I had a major failure requiring replacing the bed surface and replacing the nozzle, so since I was going to have to recalibrate anyway I got the CR Touch to install at the same time. Installation was no big deal and doing the firmware upgrade was easier than I expected. Figuring out the UI changes was a bit annoying (all the old options are still there, but the menus are different), but running the calibration is simple. What I wasn't expecting was how much better my prints would end up. Post calibration the printer compensates for the bed warp by moving the Z axis to maintain a constant distance from the print bed to the nozzle anywhere on the build plate. Now everything is just press print and go instead of having to tweak the bed height based on where on the bed the print will be. Wish I would have bought one years ago.

Worked as expected Nice that it also includes several nozzles.

I bought this because my Ender 3 E, which has one pre-installed, works really well. The auto bed leveling on that printer works great and. But when I got the CR touch for my Ender 3 Pro, that's when the disaster started. First of all, for those of you familiar with Creality products, you will know how terrible their instructions are and they often have incorrect information. And what's with the super tiny print! The CR touch instructions are not the worst, but they are full of inaccurate information. Next, the install is not super difficult, but you have to go online to find some pictures so you know the correct cable to unplug from your motherboard when you plug in the CR touch. Mounting it on the print head assembly is fairly easy. The firmware update process is straightforward, but don't look for CR touch firmware, there is none, you have to use the BL touch firmware. It's the calibration step where everything just went completely off the rails. After you install the CR touch and do the manual bed level, you have to set the Z axis offset so the CR touch knows exactly where the nozzle needs to be. The CR touch unit would never properly adjust for the Z axis offset. If I manually moved the Z axis to 0 with the offset applied, the nozzle is in the correct location, but when the CR touch went to do it's bed level, the print nozzle is too high and no matter what I set the Z axis offset to, the CR touch unit ignored it and had the exact same spacing between the nozzle and the bed, which was approximately 1.5 mm too high. The result was failed print after failed print because the CR touch was telling the print head that the proper Z axis position was wrong. I emailed Creality support, and in typical fashion they wanted photos and videos and all other manner of proof that the printer was doing exactly what I described. They never actaully address any failures, they just continue to ask for additional information until the customer gets frustrated and just gives up trying to get resolution. And how exactly am I supposed to send a 5 minute video showing the failed calibration? This is not my first 3D printer. I have several FDM printers and a resin printer. And my Ender 3 pro works very well with manual bed leveling. I was adding the CR touch module so I would have to adjust my bed level a little less often, but the CR touch is a complete failure on the Ender 3 pro. I don't know if it's the CR touch or something in the firmware, because the printer doesn't seem to take the home position offests either. But either way, Creality support seems unwilling to help resolve the issue so I am returning my CR touch and providing this warning: IF YOU HAVE AN ENDER 3 PRO, THE CR TOUCH WILL NOT WORK!

Before I was spending an insane amount of time leveling my bed manually, checking so many various spots… never again. I installed the CR Touch, leveled four corners manually, auto leveled, and conducted a test print. Everything came out perfect. I have my printer settings so it auto levels before every print now. The install was a breeze. Make sure you check your motherboard before purchasing and installing. If two hours of time is worth $38 dollars, this will pay itself off QUICKLY. Get your time back.

El CR Touch que venía de fábrica en mi Ender 3 V3 SE me daba demasiados problemas con un error "CR Touch error, please contact custumer service", hasta que lo cambié y de momento no me ha fallado ni una sola vez, de hecho, hasta pareciera que este es de mejor calidad y la calibración mejoró bastante. Este es el sensor que debería de venir de fábrica. No hubo necesidad de instalar firmware ni nada adicional, solo reemplazar la pieza y ya.

Instalar el CR Touch fue el upgrade más útil que le he hecho a mi Ender 3. Después de batallar con nivelación manual cada dos por tres, ahora solo prendo, calibro y a imprimir. La instalación no fue tan difícil (seguí un par de tutoriales en YouTube), y en menos de una hora ya estaba funcionando. Sí es importante actualizar el firmware, pero una vez hecho, trabaja perfecto. Las primeras impresiones quedaron mucho más uniformes, sin problemas de primera capa. Lo recomiendo totalmente si buscas consistencia, menos frustración y más tiempo imprimiendo en vez de ajustando tornillos.

Este dispositivo hace perfectamente su trabajo, yo soy nuevo en esto de la impresión en 3D y esto de nivelar la cama de la impresora es algo muy importante. Con este dispositivo la cama queda muy bien y las primeras capas se adieren bastante bien. NOTA. es muy importante que primero siempre niveles tu cama manualmente y luego ya hagas el auto nivelado. Yo recomiendo que vean videos en Youtube para ver este proceso, fue lo yo hice y la verdad quedó muy muy bien. El nivelado de mi cama

Funciona de maravilla, solo que le doy 4 estrellas porque tuve que rediseñar el soporte de instalación pues no se ajustaba de forma correcta a la altura del nozzle.

con esta mejora que le di a mi ender 3v2 ya no tengo tanto problema al momento de nivelar la cama, cabe aclarar esto no te quita el hecho de que nivelar la cama cada x tiempo pero si ayuda a que las piezas queden con mejor acabado y sobre todo esa primera capa que a muchos se nos dificultaba que saliera perfecta, la recomiendo
