Okyakusama 3 The first problem is the connection cable is really short, so I had to make my own cable to reach the 3D printer's control board. Next, there is no wiring diagram included, and online instructions are all wrong in some way. I was forced to use a multimeter to verify voltage levels before connecting my custom cable. Finally, it doesn't include a bracket mount, so I had to 3D print a mount from thingiverse and manually adjust the z-offset and spring tension.After a few days of tinkering, it finally behaves correctly and so far it works perfectly. The BLTouch itself is worth 5 stars, however this listed item is missing too many things to give it more than 3 stars. It was a pain to setup due to missing parts, cables, and instructions.
