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

Worked well with my foxnovo ender 3 printer i have updated all parts on it this helps with the leveling if the bed has made my prints come out way better and more reliable. You just need to make sure you get the right software for the system you have.

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.

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.

So I've been printing with my Ender 3 for 6 months or so, and I've gotten decent at leveling the bed and dialing in the nozzle distance, but even still, my prints were coming out somewhat uneven or flawed more often than I'd like. I was getting frustrated with having to relevel the bed every single time and then finding that tiny variations in in the springs, temperature, etc. were messing up my prints, so I decided to invest in this auto-leveler. As others have noted, the installation process is a little involved. No step is particularly hard, but differences between different machine models and the somewhat vague instructions provided make it harder than it needs to be. There's some very good video tutorials available on Youtube that I'd recommend you use. After getting it attached to the machine, it took a few bed leveling test prints before I got the z-offset for the probe dialed in. Once dialed in though... I witnessed the best first layer I've ever printed. Picture shows one corner of the bed leveling test; a single layer (.2 height) square, with a perfectly uniform surface and thickness, and sturdy like a piece of cardstock. Beautiful! You might have to adjust the offset by a few points each time you print, but this is much easier than leveling manually. Even if you're a pro at bed leveling, I can't imagine the newfound ease provided by this tech wouldn't make you ecstatic. Buy it! I'm looking forward to printing new things more than ever. EDIT: My unit suddenly had a failure after about four months, where it would just fail to auto home or level. Contacted Creality and they quickly sent me a new unit for free. I just swapped out the probe and it was back to working perfectly! Great hassle-free customer service!

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
