I just got into 3D printing. A co-worker steered me to the Creality Ender 3 V2 and it arrived 10 days ago. Got it all set up and it has been working great. I was happy to stumble upon the DrVAX channel, and when I noticed the BL-Touch upgrade I knew it would be a good upgrade because my print bed is not perfectly flat. After doing the 4 corner adjustment, I noticed that most of the rest of the bed was lower--slightly bowl-shaped. I've had been sending a -0.08 z-axis offset from the Cura for all my prints up until now. But that wouldn't be enough for doing large prints taking up large portion of the bed.
So with the courage the DrVAX's YouTube video inspired, I made the plunge to do the upgrade. I followed all his steps with a few modifications:
1) I went with the v3 bracket from jkostenov and it fit perfectly. If you do the math, it places the BL-Touch only 0.6 mm further down than using the combo of the v2 bracket + 50%-reduced-height spacer shown in the video. I figured I would give the v3 bracket a try and my 4 leveling screws have plenty of travel to accommodate that. Just a bit cleaner.
2) A little one: I found there's room to place the screws oriented head-up when connecting the BL-Touch to the bracket.
3) A big one: I found that I was able to route the 2 meter cable through the wiring mesh--see photo. I tried to think of an appropriate tube to push the cable through the mesh and I ended up using the tube that the printer's z-axis screw what shipped in. It was just barely stiff enough. I snipped off all the cable ties holding the mesh. It's a matter of bunching up the mesh weave. I had to borrow my wife's hands to help, but was able to get the 2 meter cable all the way through the skinnier wiring mesh weave--from the hot end all the way to the circuit board through the inner cable mesh.
4) The latest 3DSmith FW includes several options. I went with the recommended 5x5 slow print and it is working great. It does take much more than the 25 seconds that DrVAX said his takes before each print--maybe I'll try one of the fast FW options later.
One of the attached pictures is the first layer of the Thingiverse chainmail (https://www.thingiverse.com/thing:3096598). Everything looks uniform to my eye. It's half way through the 20 hour print as I type.
Just wanted to share my experience installing the BL-Touch. Very happy with how well the upgrade worked--thanks for the inspiration DrVAX.
