Describe your issue:

Hi guys, It’s been a while since I noticed that my printer can’t home anymore after complete a print.

I mean, it can run all commands fine and park the car after finish it. But if I try to home the X axis, for example, the car moves to the home position but return a message like “Must home axis first: 15.997 179.999 230.625 [16266.579]”
the same error occurs with the Y axis (didn’t test the Z axis because I can’t even home X and Y)

But if I restart the firmware, the printer back to normal.

I’m currently using the sensorless home from my TMC2209 v1.3

these are my macros for START and END print

Try removing your G28 and see if the error persists.

My G28 is commented. It is inside the G29 command. But is was uncommented before, and has the same problem

You mean remove my custom G28?

also… this is my G28 and G29 commands

[gcode_macro G28]

gcode:
  {% if 'X' in params %}

  {% endif %}

  {% if 'Z' in params %}

  {% if 'X' not in params and 'Y' not in params and 'Z' not in params %}
