TMC2130 Sensorless homing with Marlin 1.1.9 and MKS gen 1.4 (no replies)

Hi.

I tried to use sensorless homing with tmc2130 via stallguard.

So I prepare coreXY frame, 3 X TMC2130, MKS gen 1.4

In the end, X axis and Y axis 's sensorless homing Successfully

But Z axis isn't working.

If I start Z axis homing, just go backward likes he already in touched endstop



I sent M122 for checking driver's status

All setting(likes current, motor's model) was same and even it have any load for it

In conclusion, X axis Y axis worked, but Z isn't, stallguard always on with no motor load,

Thanks in advance
