3 Fixes for BLtouch V3 on Creality machines

############################# Video Source: www.youtube.com/watch?v=sOFxalLOZOI

The BLtouch V3 has caught a lot of people out because it isn’t compatible with the some Creality and other mainboards. Fortunately, enough time has passed for Antclabs and the developers of Marin to create some fixes, three of which I demonstrate in this video. • These firmware fixes will eventually be implemented into the main Marlin branch, and this video will become redundant. • UPDATE: Marlin 2.0.X now works fine with either BLtouch version. I have a branch setup on my GitHub: https://github.com/teachingtechYT/Mar... • All three of these options made the BLtouch V3 work with my Ender 3 housing a 1.1.5 board. Since the 1.1.3 in the first Ender 3/5s and the 1.1.2 board in the CR-10 are very similar, it should work for those too. • I realise that I went over method 2 very fast, and that’s because I’ve already made a video on that process: • Ender 3 BLtouch vanilla Marlin guide • Creality BLtouch upgrade kit for Ender 3 / 5 and CR-10: https://www.creality3donline.com/crea... • BLtouch V3 specifications: https://docs.wixstatic.com/ugd/f5a1c8... • Method 1 - Update existing Marlin 1.1.9 • A list of the changes needed to Marlin 1.1.9 as shown in this video. Thanks to Phillip Beal for pointing me towards this: https://github.com/InsanityAutomation... • Method 2 - Prepare Marlin 1.1.9 bugfix from scratch: • Arduino IDE download: https://www.arduino.cc/en/main/software • Marlin firmware download: http://marlinfw.org/meta/download/ • A pre-compiled firmware hex prepared by myself for BLtouch V3 (Marlin 1.1.9 bugfix with thermal runaway protection): https://gumroad.com/products/wLtut/ • TH3D firmware already this this patched: https://www.th3dstudio.com/knowledgeb... • Method 3 - Desolder and remove capacitor for z endstop • Antclabs reference page: https://www.antclabs.com/wiring3 • Buy quality and affordable filament from X3D.
