    Ender 3 Pro with MKS Gen L - Marlin 2.0 no Z homing

    Sorry for my bad google english.

    It's about my Ender 3 Pro. For about a year it has been running with an MKS Gen L with TMC2208 and Marlin 1.1.8 and Marlin 1.1.9 without any problems. For a short time I also had it running with a 2nd Z engine. I had no problems adjusting Marlin to my liking. Now I wanted to have a look at the Marlin and made everything suitable with Visual Studio, but unfortunately it no longer does Z homing for me.

    Whether with a mechanical limit switch or an optical one, it doesn't work. With M119 he shows me triggered. If I switch it to Marlin, it will be open, but then it will not react either.

    For testing I connected a BL Touch and everything is fine with it and works without problems. In theory, of course, I can flash the Marlin 1.1.9 again, but I would like to know why. I've gone through Configuration.h and Configuration_adv.h a few times, but to no avail!

    Maybe I don't see the forest for the trees, or I just did something wrong, I don't know! Would be great if someone had an idea.

    I have attached my Configuration.h and Configuration_adv.h in the
