Part cooling fan running full speed at 0% and homing issues

I have the delta PWM fan set up as close as I can tell to what douzuki says in their build instructions but when set to 0% it appears to be running at 100% and vice versa secondly, im unable to home as y goes in the wrong direction, and when reversed goes all the way back and then and doesnt stop on the endstop and continues to drive left

Connecting a 4028 fan | RatOS
4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.

Using the mainsail interface check that x+ moves to the right (the front of the machine is when electronics panel is farthest away from you). And check that Y+ moves the gantry towards the back. If that isn't the case then use https://docs.vorondesign.com/build/startup/images/VT-motor-configuration-guide.png to adjust since both motors are used to move X and Y you can't simply reverse a single motor

Configuring RatOS | RatOS
RatOS only needs minimal configuration to work, but comes with a lot of optional functionality that you can enable manually.
