It's Alive!

After some tweaking, I got it moving! However, it was not with the custom firmware, so when I used the LCD to move the motors, it was simply the A/B/X motors moving on their own. But at least the controller is working and the motors are working.  

After some mucking around with the firmware and OctoPi, I have it all working now. As I am using a non-standard V0 build. 

• BTT SKR Mini E3 V2.0
• Keenovo 100W 24V 100x100 heater
• Slice Mosquito 24V

There were a number of firmware items that I have to change to make it specific to my build. So far the following as per the Discord pin.

1. For the Klipper configuration: During make menuconfig for Klipper firmware, in GPIO pins to set at micro-controller startup use !PA14 instead of !PC13.
2. For the printer.cfg file: 

Invert direction pins for steppers:

* in [stepper_x]  change dir_pin: PB12 to dir_pin: !PB12

* in [stepper_y] change dir_pin: PB2 to dir_pin: !PB2

* in [stepper_z] change dir_pin: PC5 to dir_pin: !PC5

* in [extruder] change dir_pin: PB4 to dir_pin: !PB4

Update TMC2209 control pins.  Note that all the steppers are on the same pins now and just have different UART addresses:

* in [tmc2209 stepper_x] , replace uart_pin: PB15 with

uart_pin: PC11

tx_pin: PC10

uart_address: 0

* in [tmc2209 stepper_y], replace uart_pin: PC6 with

uart_pin: PC11

tx_pin: PC10

uart_address: 2

* in [tmc2209 stepper_z], replace uart_pin: PC10 with

uart_pin: PC11

tx_pin: PC10

uart_address: 1

* in [tmc2209 extruder], replace uart_pin: PC11 with

uart_pin: PC11

tx_pin: PC10

uart_address: 3

In addition to the above, I made the following changes (in yellow). Based on these the heater bed and temperature seems to work (only tried to lift it to 35 °C), will do it properly when I have all the end stops and extruder sorted. The motors do not work over OctoPi as I have not set up the end stops to allow me to home.
