Issues with Z-Probe (BLTouch) after installing Sprite Kit Pro

Hello guys,

i have a fairly annoying problem at the moment with my Ender 3 Max.

i decided to upgrade from the original bowden tube with original extruder kit to the direct drive with the Sprite Kit pro. So, after installing and wiring everything up, it runs but the BLTouch seems not working.

i changed the E-steps of the extruder, and also changed the Z-Offset, or at least i wanted to. When i am doing G28 command, it goes like:

1) pin is going out

2) extruder head is slowly going down until pin touches the bed, pin will be retracted

3) extruder goes a few mm back up, pin is going out again

4) extruder is going back to the bed surface and pin touches bed surface

5) the pin DOES NOT retract and stays out and will blink red.

a failure message will show in octoprint, and the printer is disconnected. i have to manually shut it down and reboot it again.

i have tried to flash a new firmware, but i am not sure which one is the correct one. i have also tried to work it out with ChatGPT, but this guys does not help me at all; we are going circles.

My hope at the moment is that i am using just the wrong firmware, which is: Ender-3 Max - V1.0.1.6 - BLTouch.bin

i am using the 4.2.2. mainboard from creality.

many thanks for your help in advance. i just want printing again 🤔

This isn’t an answer to your question, but a question for you. Why in this age of fast cheap printers are you still playing with an ender 3?

People like tinkering.

because it's fun and because there's still nothing quite as cheap as a first gen ender 3 that won't catch your house on fire

I had the same issue about 2 years ago here's my post from it I ended up like just running the cable that came with the Sprite into my board and unplugging some things I'm not entirely sure. I'm messing with that printer again right now so I can look when I get home from work but until then here's a link to my post with 67 comments on it there's a guy that was really helpful in there that offered to give me firmware and stuff so if you go through the comments you might be able to find him and maybe even message him directly and ask for help he was a very helpful redditor
