I made the touchplate out of a small spatula I had laying around. It works pretty good – auto-home, make sure the spatula is flat on the surface, let the tool drop and set zero when it touches the plate. I then do a manual move to drop the Z by 1.2mm, and then set home offsets to reset zero.
Ryan recommended using the easily-moved endstop holder. That was a good idea, but after dozens of cuts, with resets almost every time, I’ve come up with something quicker and easier. I mounted the endstops on some cheap plastic clamps. Mine came from harbor freight. They are super easy to move, but hold their position once placed. I highly recommend them.
