Hi. I have a problem with my buck converter that I made using tutorials and schematics online to help. I have used several different voltage supplies to test the circuit but only one of them works. It is a 12v supply that works and I have tried other 12v supplies but they do not work properly! The output voltage is fully adjustable from 1.8v to 12v while using the one 12v input, but for all other voltage supplies I use the output voltage is either not adjustable or only adjustable between about 2v range.
Here is a schematic of my circuit.

I am not an engineer or fluent with circuits, I am just playing with electronics at home. This is my first time asking a question about my circuits. I'm sorry if I have omitted any needed information.
