Hi,
i soldered the rate pin to 3.3v but the rate i can get values in a loop stays the same. How do i get up to 80sps? (I am using a rpi zero)

Thank you

If you look at the picture: https://github.com/gandalf15/HX711/blob/master/rate_pin_80sps.png
the "leg" on the HX711 chip is actually lifted up and it cannot touch the board. So, I would suggest using tweezers, heating up the solder and simultaneously lifting up the leg from the board. Afterwards, solder a cable to that pin.

I did it, but it didn't change anything

If you measure voltage with multimeter, what is the voltage on the pin? Can you send a picture? If you try continuity with multimeter do you have it to VCC do you have it to Ground?
How often are you trying to read the HX711 with your code? Can you send a snippet of your code?
Thanks.
