Ender 3 Pro with CR Touch and Silent mainboard problem

I’m completely new to the world of 3D printing. I’ve installed a Silent Mainboard 4.3.7 in my Ender 3 Pro, removed my Z endstop, and connected a CR Touch. I’ve also replaced the original magnetic bed with a glass bed. I’ve been searching for a solid solution for days now, but I have no idea where to look anymore.

Using the Firmware Builder hasn’t gotten me much further so far, but I fear that’s partly because I don’t always understand what’s being asked of me.

Does anyone have an idea where I can go with my current configuration? I assume it’s not too unusual of a setup. But right now, I’m quite discouraged by everything I’ve tried so far without success.

Thanks in advance for your attention.

Kind regards,
Dave
