Sensorless Homing doesnt work


Recommended Posts

Hi, my sensorless-homing isnt working.

Everytime I try to home my printer the bed and printhead just smash into the frame eventhough I set the sensitivity to the maximum and enabled sensorless-homing

 

When I use the G-Code Command M122: I get the followinng informations:

The Stallguard Threashhold always seems to be zero eventhough I have flashed multiple firmwares onto my printer correctly with different stall sensitivities

 

 

My Hardware:

I am using TMC2209 v1.2 by BTT on an Octopus Pro V1 with the STM32F446ZET6 chip.
I have put the Jumpers on all axis in UART mode.
I have put in the DIAG jumpers for Stallguard in the X and Y Axis Pins.
My steppers-motors are all powered correctly with 24V.
My motherboard is powered correctly with 24V.
I am using a BL-Touch for homing the Z-axis.

I unplugged all the Endstops.

 

 

My Software Configuration (Marlin 2.1.2.1):
I defined my Motherboard to: BOARD_BTT_OCTOPUS_PRO_V1_0.
I defined my X, Y, X and E Drivers to TMC2209:  #define X_DRIVER_TYPE  TMC2209, #define Y_DRIVER_TYPE  TMC2209, #define Z_DRIVER_TYPE  TMC2209, #define E1_DRIVER_TYPE TMC2209.
I defined Sensorless Homing: #define SENSORLESS_HOMING.
For Test-purposses I set the X and Y Stall sensitivity to 255:  #define X_STALL_SENSITIVITY  255, #define Y_STALL_SENSITIVITY  255.
