skr 3 with ez2209 endstop issues

[dannikka]

I have a skr 3 with tmc2209 driver in uart mode and sensorless homing and all works fine, so i decided to upgrade my drivers to ez2209 with ez driver connectors for better heat dissipation and after installing the new drivers my printers was homing in the wrong direction. what i have worked out is the end stops are showing triggered with the ez2209 but open with the tmc2209 ?????

I am trying to figure this out as well. It looks like the pinout between a TMC2209 and the EZ-Driver Controller is different. Somehow it must be possible to say "The diag pin is actually over here" but I don't know how. I will post back here if I figure something out.

The EZ-Driver Connector board does not have the DIAG pin at the expected place. I don't even think it will fit as the driver slot overlaps the place where the header will go. Hopefully BTT will fix this with a new Connector board release.

I have solved this by soldering jumper cables to the DIAG pin and directly routing them to the X and Y endstop min pins.

@markbastiaans, I followed your solution - it works, thanks!
