After some research, the BlTouch can be wired to the mainboard two different ways; the 2 pin wires (that were black and white in the kit I bought) are able to plug into the probe spot with the 3 pin wires or they can replace the z-end-stop. I ended up replacing the z-end-stop wires with the 2 pin wires and downloaded pre-compiled firmware from GitHub.

If you check TH3D's site, as of January 12, 2022, there's an updated Unified 2 firmware(Unified 2.36a) that is meant to correct this problem. Announcement is here: Unified 2.36a is now live! | Firmware Update Release Notes: Bugfixes Disable ABL fade height by default Fix EZBoard V2 DIY Config Driver Type Setting Other Changes Update URLs in config files ...

You have written in the comments that I did not do anything with to the wiring or firmware when it stopped working And that you tried Swapping the BLTouch out for the one that belongs to my other printer And testing the BLTouch with another printer It seems from these statements that the answer to your question is: something got damaged in the SKR ...

Just thought that BLTouch could automatically measure the nozzle height. If it goes down slowly till nozzle touch the bed and then push down a little more then it will see sensor isn't moving anymore then it means nozzle already pushes the bed down. Beds are usually have springs and shouldn't hurt to push it a little (~1mm) by nozzle. Not sure if such ...

There's also the option to save the mesh so that you don't have to level each time you print. First of all, using Cura or whatever you use to send commands, send: M502; Reset to factory settings M500; Saves (so that you may start with a clean slate) G28; Home All G29; Autolevel After running your auto bed leveling, add M500 And you're done. P.S. don't ...

You need a crimping tool like this so that the pins will be crimped correctly to fix in the sockets and plugs.

You need to check the X gantry, the Ender design is flawed by using a single Z screw on one side. Please check the rollers and check the belt tension. All the leveling graphs show that the bed is lower on the right side (or the gantry higher), it could be that the rollers on the right post (when facing the printer) are causing the right side to be lower.

The most probable reason is that your Z offset is too small, the nozzle is too close to the build plate, when molten filament has too much friction to flow out of the nozzle, the back pressure causes the extruder to skip back making loud thumping/knocking sounds. You could increase the Z offset for instance or redefine the bed height with G92.

Are you using Creality's pre-built software? In that case, you must connect the two pins to the BLTouch port. Altogether, you would have all five wires connected there. Are you using your own Marlin build? In that case, you must uncomment #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN in order to plug in those two wires into the Z end stop connector. Otherwise, ...

I solved the same issue. I had the same problem, just send the G-code M502 to your printer through Cura or whatever it is you use. The reason is that you already did an auto bed leveling and you more than likely send the G-code M500 which saves your auto mesh data so that you don't have to auto home for every print. So M502 restores everything to its factory ...
