I am am getting an error when I try to home the print head, here is the error:
Unable to read tmc uart 'stepper_z3' register IFCNT
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
and it also says btt_mini12864 is not valid for LED
here is my config if you need it.
Thank you in advance for your help!

What mainboard are you using? That is the kind of error you usually get when the pinout isn't quite right or jumpers aren't set correctly and the mcu cannot talk to the stepper driver (in this case over uart serial).
That LED error is probably you have gcode trying to control a led named btt_mini12864, but it's not defined anywhere. You need to have one defined (https://www.klipper3d.org/Config_Reference.html#leds) with a name that matches the one you're trying to control with SET_LED.

pinout for steppers seems reasonable. have you double checked that the jumpers (under the stepper driver modules) are set for UART mode, and that you have them in the correct slots (the first six)?
