You seem to have indicated that you just have PB6/PB7 wired. I would still like a picture of what you have done and how things are wired.

You indicated that there is a problem with getting 'scope pictures of the data. With the soldering/desoldering (I was expecting that you would only use plug in connectors) I think it’s really critical to see what’s going on the lines. I don’t understand why you are unable to get a shot of what’s going on the line.

ok, I won’t move on to plan B for now. )))

1. this is what my connection looks like now. !!!no resistors to the wiring!!!

nothing happens on the oscilloscope! !!!voltage 3.36v!!!

until the bus transmission starts! but the transmission does not start, a Klipper error appears

Stop posting abbreviated/edited klipyy.log files. I would really like to see the complete file. If you think it is too large (although you should be able to .zip it and post it here), then do a Reset on the Mainsail “Machine” page and then post the new file after you’ve run a new test.
