Creality CR Touch kit, Professional 3D Printer Auto Bed Leveling Sensor Kit. Specially Designed for Ender 3 v2/ Ender 3/ Ender 3 Pro/Ender 5/Ender 5prol/CR10, More Durable Than BL Touch

I use this with mesh bed leveling. It has saved me sooooo much time and prints. At least 90% of the time I either start the print remotely from another floor of my house or I hit the start button on the printer and walk away.I've leveled my bed 3 times since installing the CR Touch. I leveled the bed when I first installed it, I leveled the bed again one day when I noticed that the top layers of my prints were stair stepped a little even though prints still stuck to the bed and then I leveled it again after removing the bed and replacing a broken belt. The printer creates a new mesh before starting every print.The trick for me was to figure out a good initial layer height for my most used filament type, I chose .28 for PETG. I set my Z height for a good squish at .28 and then I changed ALL of my PETG profiles to have an initial layer of .28. Yes, even my .12 layer height profile starts at .28. Next, when I went to print TPU, I left the z height alone and I adjusted the initial layer height to get a good squish. That height was .22.

UPDATE 11/14/21: Ever since posting this review, I've been receiving multiple "bribe emails" on removing this 1-star review and refunding me starting from $20 with an increment of $5, to the highest they can offer, $50, and starting over from the bottom, which is $20 and repeating the ever spamming bribe emails from different GMail accounts. I had some fun whether they go over $50, but I will not remove my review nor do I ever plan on to. It is here to stay. If this review happened to be removed somehow then that would be amazon's doing.tl;dr: I've had more readjustments of the bed level and Z Offset than manual bed leveling.I'm a newbie to 3d printing, I became frustrated after much attempts on getting CRTouch working and decided to go back to doing manual bed leveling.This is how I became an expert in manual bed leveling from the amount of bed leveling I had to do.---Some of the people out there may have successfully gotten their CRTouch working perfectly like a well oiled clog machine, while some don't.Unfortunately, I happen to be one of those people that couldn't get the CRTouch working perfectly.So, right out of the box, a manual, 3 different metal plates to hold the CRTouch (for different Ender 3 printers), 3 zip ties, the cable to connect the CRTouch to motherboard, 2 M3*8 and M3*6 screws, the CRTouch itself, and a card that asks the buyer to give this product a 5 star review, screenshot the review, send it off to their email, and free $25 amazon gift card.That's one hell of a way on buying reviews; almost too tempting but I resisted, simply look at the star I gave.Installation of the CRTouch was easy with the use of common sense, but the instructions on the manual was full of google's broken translations.I have a Ender 3 V2, simply power off the printer (and unplug the power cable for safe measures if you're paranoid), unplug the Z-Stopper (and remove it as an option), find the correct plate for the CRTouch, mount it on the header, wire the CRTouch to the motherboard, plug the power cable back to the printer, and bam you successfully installed CRTouch. Simple as 1, 2, 3.Now here comes the part where I have to flash the firmware. They direct you to their website to download the firmware for both the printer and CRTouch. However, the Ender 3 V2 comes in 2 different version of the motherboard, in which you don't get to choose on purchasing the printer (bought mine here on Amazon), 4.2.2, and 4.2.7; Which it doesn't says anywhere in the printer but on the motherboard itself, so good luck.Luckily for me, I already knew what version the motherboard was, that being 4.2.2. Having gone through some attempts on flashing the printer with the new firmware, it took me a bit to realize that BLTouch and CRTouch both uses the same firmware, I had expected Creality to have their own firmware for this, but apparently they don't. At the time of typing this review (7/14/21), the current firmware is "Ender-3 V2-Marlin-2.0.1-HW-4.2.2-mainboard-V1.1.2-Compatible with BLTouch and filament detection.zip"Threw the .bin file into the SD card (and make sure you have DWIN_SET folder copied from "Ender-3 v2 4.2.2mainboard（32bit）.zip"), plugged into the printer, powered on, several seconds later the screen came to life with Creality logo displaying in all its glory.Now comes the fun part, setting the Z Offset.The manual was not meant for Ender 3 V2 users to follow, but for other Ender 3 printers which I presumably, the Ender 3 Pro; how? both printer have different user interface.I had to look up a video on setting the Z Offset, which was simply autohome, set the Z-Axis to 0, get a A4 paper and slap it onto the bed, adjust the Z Offset until you can feel some resistance from the nuzzle when moving the paper back and forth. Bam, setting the Z Offset, done.Then I had to go back to the main menu and select Level that probes the bed, in which I later learned and could be wrong, that it stores the mesh level values for prints; awesome!But what's not awesome was that I had to level the bed, and I didn't know I had to do that until much later.Here comes series of adjustments, but before I do so, I had to add a single GCODE line on my slicer (Cura), I had to add "G29 ; " under "G28 ; Home all blah blah blah" on my printer profile, use that profile, slice the print, and loaded onto the printer; nice.After starting up the printer and starting the print, it went through the GCODE script by first autohoming, and then probing the bed (caused by the G29 ; line). Once it was done probing the bed, it went ahead and started the print by doing the prime blob (the initial long line of wasted filament at the very left side of the bed), right off the bat I see a problem, the nuzzle was too low and was barely scrapping the bed; no problem, I readjusted the bed level to go lower just enough to see the filament coming out, but much later on the bed level was too low and the initial layer was not able to stick onto the bed; WELP, I went and cancelled the print, went through the entire process adjusting the Z Offset and the bed level again.Started the print again and the same problem occurred. This went on for some time which baffles me to no end since I was not able to have at least one successful print with the CRTouch.I looked online for tips and tutorials, adjusted the Z Offset and leveled the bed PERFECTLY, nuzzle too low. I don't know if it's either the firmware is wrong, a bug, etc., but it got to the point where I simply unplugged the CRTouch, remounted the Z Stopper, leveled the bed which took me no longer than 5 minutes, did a test print, goldilock. Nuzzle wasn't too low nor was it too high. It was perfect, and out came the filament like butter.So is the CRTouch worth it? In my opinion, no, but learning how to level a bed properly? Yes.I'm not going to stop you from being you; so good luck and enjoy having to get the damn thing working as it's intended purpose.

Alright, listen up fellow 3D printing wizards, I've gotta spill the beans on the Creality CR Touch Auto Bed Leveling Sensor Kit. Seriously, where has this thing been all my printing life? This kit is like having your very own bed-leveling fairy godmother – it's a game-changer, no doubt about it. If you're as serious about 3D printing as I am (or even if you're just dipping your toes in), you need this upgrade ASAP. Trust me, you'll save time, your sanity, and probably a boatload of filament.So, let's talk setup. Now, I'm no tech guru, but I managed to slap this bad boy on without any major hiccups. The instructions are actually friendly, and you won't need to call in a team of engineers to decipher them. Once it's in place, the real magic kicks in. The CR Touch sensor does its thing, auto-leveling your bed before each print. That means your first layer is practically guaranteed to stick like glue and the chances of a print disaster drop big time.But wait, there's more! Brace yourself for the smoothest calibration process you've ever seen. Seriously, I'm not joking. The software holds your hand through the whole setup, making you feel like an expert even if you're a total newbie. And the sensor? It's like a bed height detective – no more manual fiddling around.Here's the kicker – this thing's built like a tank. I've put it through its paces for a few months now, and it's holding up like a champ. Solid and reliable – what more could you ask for?Let's talk prints. Oh boy, my prints have never looked this crisp. Whether you're tackling intricate designs or big, functional parts, the CR Touch keeps each layer on point. No more lumpy surfaces or layers peeling off. It's like a magic wand for perfect prints.Now, here's a juicy nugget – I'm an Ender 5 fanatic, and guess what? This kit plays nice with my printer too. It's like peanut butter and jelly – a match made in 3D printing heaven. I slapped it on my Ender 5 and watched it level up like a boss.Bottom line: the Creality CR Touch Auto Bed Leveling Sensor Kit is like the fairy godmother your 3D printer deserves.

Mounting brackets missing

I want to start off by saying overall after the installation was complete I am happy with the installation. but come on creality, 5 Cable ties?? 5?? for 50-60.00 a nice gesture would have been the incusion of 5-10 reusable velcro cable ties.This review will be for the installation of the CR touch on an Ender 5 Pro with a 4.2.2 mainboard with original firmware from Creality.The physical installation of the CR touch was eventful. I had to take off Y axis drive belt as the crimp holding the drive belt to the Extruder truck was interfering with the CR touch and its supplied bracket.I wanted to route the new wiring thru the factory loom which after an hour or so was more work than it was worth so I ended up just securing it to the outside as most people end up doing.routing into the base of my printer to plug in was straightforward and lots of length was provided to allow it to connect with no strain. MAKE SURE YOU UNPLUG YOUR Z AXIS LIMIT STOP WHEN INSTALLING. Creality put a bit of hot glue on all connectors which turned out to be a minor inconvenience when unplugging as well as some was interfering with the connection point on my mainboard. a few trims with my flushcutters dealt with those rather quickly.Firmware installation:the manual states to head to creality's website to download the firmware required to operate the printer with the upgraded CR touch. Imagine my surprise when there is no Creality firmware specifically for the CR touch, however there is one version for the BL touch. I gambled and won on installing the Marlin firmware for the CR touch (so you know it works but you have to do the steps below to get it to work properly.)After installation of the Marlin firmware you then have to figure out your Z offset. Mine ended up being -1mm but your mileage will vary. DONT FORGET TO PRESS SAVE SETTINGS AFTER EVERY MODIFICATION.Now that i had my printer upgraded with my CR touch and my fancy new Marlin Firmware i thought i was home free, but oh no... because of the upgrade in firmware my filament feed stepper motor was running reverse as it was with Creality's firmware. There are two methods to inverse the direction of the stepper motor, one being coding in the firmware change and one being wiring changes on the stepper motor. I opted for the wiring change option.I had to take the 4 wires which power the stepper motor and change them from wiring in ABCD and change the wires to DCBA, being careful not to damage the crimps on the ends of the wires and damaging the plastic wire connector. there are many forums discussing this option and the reprogramming option.After all of these steps were complete I finally got some great prints with my original settings on Cura and they turned out great. As stated by others there is more noise now from the probe being vibrated in the CR touch which is VERY NOTICIABLE. i have not figured out a solution to rectify this at this point.i was glad that i installed as now running Marlin i was able to increase the speed of my prints from 50-60mm/sec to 80-90mm/sec without hurting quality.my bed was super level before installing and I havent tested to see if it makes an actual difference as bed adhesion was not too much of an issue before for me but it seems to work just fine.
