A5 -> MKS Gen L V2.1 -> TMC2209 -> Marlin 2.06 -> Problems with Homing / Sensorless Homing / Endstop

Hi folks!
I'm new to this forum! I'm from Germany and I own a JGAURORA A5.
It worked ok but loud with the default stepper drivers.
I upgraded my JGAURORA A5 from MKS Gen L 1.0 to MKS Gen L 2.1 with TMC 2209 2.0 drivers.
I also downloaded nightly build of Marlin 2.06 with JGAURORA Comfig file.
I followed this Makerbase Video about configuring the board with TMC2209 for all four servos (X,Y,Z,E0) and sensorless homing.
I can move the axis but the sensorless homing is not working at all. None of the mechanical endstops is reacting to M119.
No matter if they are triggered or not, they do not change their state in Marlin. And the X and Y axis run into the mechanical end and make a horrible noise.
Send: M119
Recv: Reporting endstop status
Recv: x_min: open
Recv: y_min: open
Recv: z_min: TRIGGERED
Recv: filament: TRIGGERED
Recv: ok
Anyone here, who has the same config running?
I want the X, Y and Z axis with sensorless homing. The Extruder can run normally.
Do I need to unplug the mechanical endstops or is this a no-go? At the moment the mechanical ones are connected to the board.
When the printer is able to print again, I want to add a IR-Sensor for autoleveling.
Thanks for your help!
Best regards
Marc (from Germany)

    Welcome (Willkommen!) @Marc - I'm sorry, the double post was my mistake. The forum is always suspicious of first posts, and it thought your URL (youtube link) was spam. I approved your comment then there were two... sorry about that!
    As strange as it sounds, in general you want to use the configuration for the board you are using, and not necessarily the A5 configuration. Especially since you want to use sensorless homing. I have not tried setting up that feature, so I don't think I can help there. I would start with the MKS config that matches your new motherboard, and then you can change the max X Y Z limits in the firmware and see how that goes. I think most other things should be unchanged...
    Best of luck! Good on you for giving custom firmware a go! 👍👍👍
    Kind regards,
