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

Easy enough to install. Have to route a long cable through the umbilical sleeve to the head, but easy enough if you’re patient. This takes the place of the Z limit switch, so that switch can be removed entirely if desired. The firmware for your board has to be downloaded from Creality and updated. My issue with this firmware is that frequently the board resets to defaults when turning on now so everything has to be reset. The menus come up in Chinese when that happens so you know your settings are gone. ( This happens every few restarts) Also when it happens, the Z offset has to be re-programmed. I finally just wrote down the values and re-enter the values without going through the whole process now. That’s my issue with the kit. Other than this, when everything is working correctly, the auto-leveling works great. I don’t have to manually re-level the bed every couple of prints now. Worth the money for the upgrade, IMO. Just wish the Creality firmware issue would get addressed.

Came quick and I have enjoyed it every print since installing. Installation was easy and the company has some pretty good documentation and videos to help you through the process. The build quality seems solid and after the correct firmware flash it was up and running like it was always there. The multi-point mesh bed leveling is great and has solved a lot of my layer issues in my prints. I wish I bought this sooner. Do recommend and would buy over and over if I needed to.

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.

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.

Update: Contacted Creality Support, submitted information about what happened with a video of the issue, they are sending a replacement. My other one is working fine. So I'm sure it was just the luck of the draw. It is a little different leveling, and I still recommend a manual level, and switching out the springs for spacers. I have two of these on two different printers, one failed functioning at probably 25 days, but I did not identify it until I replaced the motherboard about 5 days later thinking there was a problem with that. A little bummed. It is a process to refresh the firmware on your printer. I think I had a faulty original 4.2.2 motherboard too which may have lead to the failure. Either way, not a bad price, but as for reducing leveling workload I think there is not a time savings just a different way of leveling, and I still don't trust 100%, as I like to level manually once in a while and use spacers instead of springs for a more stiff and level bed that is less likely to shift.

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.

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.

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
