Troubleshooting • Raspberry Pi 5 + BLtouch

The raspberry pi 5 doesn't work with bltouch 3.1?

My friend has a pi4 and it works perfectly fine.
We assume it's to do with the PWM0 ports on the Pi 5 don't exist or don't act the same way

I've hooked the bltouch as follows but doesn't work:

white → GPIO0
black → GND next to GPI0
yellow → GPIO27
brown → GND
red → 5v

I've also made the pi 5 a secondary mcu to be able to control the bltouch

Is there a reason why this is different to the pi4.

Any solutions or has this been a waste of money and time?
