What happened?

GPIO36 have LOW state allways. GPIOs 39, 34, 35 works fine, also I've try use gpio21 for limit switch - it possible way, but not good option.

GPIO36 Does not have an internal pullup. You need to add one externally. That controller does have one, but it is possible it is not working. Can you measure the voltage on the pin with the switch open? It should be 3.3v. If it is not check to make sure the resistor is installed correctly.

Oh, sorry! Of course, just a bad soldered R2. Fixed, works now.
