BTT SKR 1.3 and BTT TMC5160 v1.2 SPI mode

thingiverse

This is a concise summary of my attempt to synchronize drivers TMC5160 v1.2 and SKR1.3. 1. First, please clip the pin on the driver as shown in the picture. 2. Prepare the skr 1.3 board for SPI communication according to standard procedure: remove all jumpers from the board and place only four jumpers in each driver area you wish to use, as per the picture. 3. Configure Marlin: - In configuration_adv.h, add the following lines: - #define MINIMUM_STEPPER_POST_DIR_DELAY 20 - #define MINIMUM_STEPPER_PRE_DIR_DELAY 20 - #define MINIMUM_STEPPER_PULSE 0 - #define MAXIMUM_STEPPER_RATE 400000 - #define X_RSENSE 0.075 - #define X_CHAIN_POS -1 - #define TMC_USE_SW_SPI - #define STEALTHCHOP_XY - #define STEALTHCHOP_Z - #define STEALTHCHOP_E - #define MONITOR_DRIVER_STATUS - #define SQUARE_WAVE_STEPPING - #define TMC_DEBUG - In configuration.h, add the following lines: - #define SERIAL_PORT 0 - #define SERIAL_PORT_2 -1 - #define BAUDRATE 115200 - #define MOTHERBOARD BOARD_BTT_SKR_V1_3 - #define X_DRIVER_TYPE TMC5160 - #define Y_DRIVER_TYPE TMC5160 - #define Z_DRIVER_TYPE TMC5160 - #define E0_DRIVER_TYPE TMC5160 4. Move the jumper for selecting the power supply to the left position, and supply the board with an external power source. The drivers will fail communication if supplied over USB from the PC.
