calibration of HX711 #9

Hi @Morrious, I tried to calibrate my HX711. As I was getting some wrong values after my calibration, I started to debug what can be wrong.

Now when I calibrate a weight scale multiple times, I see that the weight multiplication factor comes different each of the time. And this is the same issue I am having with other weight scale. And for some hx711, I get error of GPIO pin not ready even after having the same connection just that GPIO pin is different and I am mentioning the correct GPOI pins too. I even checked if it works with the GPIO pin number where in other HX711 gave me some values, but i get the same error there too.

Also, when I check for raw_gpio values, will it change each time I check it even after not changing any weight? like in the following image. image
