Sensorless Homing works perfectly fine for X-Axis, However, it's not working on Y-Axis. I checked the Endstop status using M119 command and Y is always showing triggered. When I give the homing command to Y-axis, it jerks towards the Y+ ( and moves like 5mm towards the y-max position)
I am using regular SKR 1.4 Board and (Not the turbo one)
-> I have used a jumper to connect the Y-Uart Pins as described in the SKR 1.4 board manual.
I am using Fystc TMC2209 v3.1
-> for both x and Y-axis
-> I have enabled sensorless homing in marlin
-> I am homing toward min position. (#define USE_YMIN_PLUG) (Y_HOME_DIR -1)
-> Endstop pull-ups has been enabled (#define ENDSTOPPULLUPS)
-> Endstop inverting has been set to false (Y_MIN_ENDSTOP_INVERTING false)
-> Homing Dir Inversion is false as described in multiple places on the internet (INVERT_Y_DIR false)
Things I did.
-> Reinstalled the latest version of the marlin and reconfigured it but didn't work.
-> Decreased the sensitivity of the Y-axis driver to 1 but still, endtsop status was still showing triggered and was not working.
-> Replaced the Y-axis driver with a new one but nothing happened.
-> Checked the voltage on the DIAG pin and it was High, (However it should be low as far as i know)
X-Axis works perfectly fine and homes correctly. But Y-Axis has this issue. Can someone please help me.
