Review on Professional Auto Leveling Specially Designed by Jason Lockwood

UPDATE 11/14/21: Since posting this review I have received several "bribes" via email for deleting this review from 1 star and I start refunding at $20 in $5 increments up to the highest offer which is $50 and starting at the lowest value of $20 and keep getting repeated bribe emails from different gmail accounts. I've had fun when they go over $50, but I won't delete my review, nor do I intend to. It's here to stay. If this review was somehow removed it would be Amazon's work.tl;dr: I had more bed level and Z offset adjustments than manually leveling the bed. I'm new to 3D printing, I got frustrated after trying a lot to get the CRTouch to work and decided to manually level the bed again. This is how I became an expert in manual bed leveling thanks to the amount of bed leveling I had to do. ---Some people can successfully get their CRTouch to work like a well-oiled weed while others don't. Unfortunately, I was among the people who couldn't get CRTouch to work perfectly. 3 different metal plates to mount CRTouch (for different Ender 3 printers), 3 cable ties, a cable to connect CRTouch to the motherboard, 2 screws M3*8 and M3*6, CRTouch itself and a card that the customer asks to give this 5 star product review, take a screenshot of the review, email it and get a free $25 Amazon gift card. It's a hell of a way to buy reviews; Almost too tempting, but I resisted just glancing at the star I gave. Installing CRTouch was easy with common sense, but the instructions in the manual were full of incorrect google translations. I have an Ender 3 V2, just turn on the printer, turn it off (and unplug the power cord for safety if you're paranoid), unplug the Z-stopper (and remove it as an option), find the right plate for the CRTouch, put it upside down, connect it to CRTouch on the motherboard, reconnect the power cord to the printer, and you have successfully installed CRTouch. Same as 1, 2, 3. Now comes the part where I need to flash the firmware. They direct you to their website to download the firmware for the printer and the CRTouch. However, the Ender 3 V2 comes with two different motherboard versions that you can't choose when buying a printer (mine bought it here at Revain), 4.2.2 and 4.2.7; What is not written anywhere in the printer, except on the motherboard itself, so good luck. Luckily I already knew the motherboard version, so 4.2.2. After trying multiple times to flash the printer with the new firmware, it took me a while to realize that the BLTouch and CRTouch were using the same firmware. I was expecting Creality to have their own firmware for this, but apparently they don't. At the time of writing this review (07/14/21), the current firmware is "Ender-3 V2-Marlin-2.0.1-HW-4.2.2-Motherboard-V1.1.2-compatible with BLTouch and thread detection. zip" Place the .bin file on the SD card (and make sure you have copied the DWIN_SET folder from "Ender-3 v2 4.2.2mainboard（32bit）.zip"), connect it with the printer, turn it on, after a few seconds the screen came alive and the Creality logo was displayed in all its glory. Now the fun part, the Z offset adjustment. The guide was not intended for Ender 3 V2 users, but for other Ender 3 printers, which I presume are Ender 3 Pro; how? both printers have different UI I had to watch a video on how to adjust the Z offset which was just autohome, set the Z axis to 0, take an A4 paper and bang it on the bed, adjust the Z offset until you get a resistance felt from the side of the nose when moving the paper back and forth. Bam, Z offset adjustment, done. Then I had to go back to the main menu and select level exploring the bed which I found out later and may be wrong that it stores the grid level values for otp echatkov; Great! But what is not surprising is that I had to level the bed and didn't realize until much later that I had to do it. And here are a bunch of settings, but before I did that I had to add a line of GCODE on my slicer (Cura), I had to add "G29"; in section "G28; Home all blah blah blah" in my printer profile, use that profile, clip the print and download it to the printer; Nice. After starting the printer and printing it went through the GCODE script, first autohoming and then bed checking (caused by Line G29 ;) After feeling the bed he went ahead and started printing making the primary drop (initial long line of used filament on the left side of the bed), immediately I see the problem, the nozzle was too low and barely scratched the bed ; no problem, I adjusted the height of the bed so it went down just far enough to see the thread coming out, but much later the bed height was too low and the original layer couldn't stick to the base WELP I went and canceled the print went through the whole process again and adjusted the Z offset and bed level Print started again and same problem this works fine On has been like this for a while, which is confusing to me as I couldn't even make a successful print with the CRTouch. I searched the web for tips and tutorials, adjusted the Z offset and leveled the bed to PERFECT, nose too low. I don't know if the firmware is wrong or a bug etc but it got to the point that I just turned off the CRTouch, remounted the Z-stopper, leveled the bed, which took me no more than 5 minutes, did a proof, Goldilocks . The muzzle was neither too low nor too high. It was perfect and the thread came out like butter. So is CRTouch worth it? In my opinion no, but learn how to level the bed properly? Yes. I won't stop you from being yourself; So good luck and have fun making this damn thing work as intended.
