I got a Fysetc 0.2 Pro R1 Kit. I couldn’t print yet because of the obvious heating problem, but other than that everything seems to work fine.

+ Double-Checked the wiring
+ Used a different 24V power source
+ I can give the command that the heater should heat up but nothing happens.
+ No error messages until klipper shuts down because the temperature doesn't rise.
+ I measured the Voltages for the HB and the nozzle they are both 0 V all the time.

So lets review, you request heat, Klipper sends the command but nothing happens. So 24v is not coming out. Board is probably bad.

When you say you double checked the wiring. How is it wired?

Yes, that is pretty much what happens.

It is wired as it is shown below.

And when you request to heat the bed, can you measure here with a multimeter?

Yes, i was referring to that before. I requested heat and measured 0 Vs. Same goes for the nozzle too.

Yeah I just wanted confirmation before saying the board is bad but it seems like it since Klipper is trying to fulfill the request to heatup.

Before you say the board is bad, check that the pin number in the config file is correct. All you need is a small typo to make it not work. My config uses "gpio" number system so I cant compare. Double check the pin names

The heater pin on both the catalyst board and the Cheetah 3.0 board is PC8, not PA9
