Z Axis stepper motor runs backwards on my SKR mini E3 V3.0

[Richard]

I have installed an SKR mini E3 V3.0 on my Ender 5 and the Z axis stepper motor runs the wrong way. I have double checked all connections and I am fairly sure I have everything hooked up properly. When I command the Z axis to go up it goes down and when commanded to go down it goes up. I have tried various firmware builds and nothing has changed. 

I am running Marlin bugfix-2.0.x (May 28 2022)

My TFT35__E3_V3.0 is running firmware V27.x May 23 2022 in 120Mhz.

Find this section in configuration.h, change as you require (below are how I set it for my anet a8):

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR false
#define INVERT_Z_DIR true

Things started working my Ender 5 when I went and put the TFT35 V3.0 back to the download that is on the BTT download page. I reinstalled the CR-Touch and the Z-Axis stepper does not home properly. It moves within about 3 inches of the top then stops. For the heck of it I tried the bed leveling on the TFT35 V3.0 and the system goes through the motions but the hot end never touches the Z axis plate. I have uploaded the Ender 5 BL touch firmware on this website.

Any ideas?

Thanks for the help!
