Unable to read tmc uart 'stepper_z' register IFCNT

[dodoguigui]

Hi,

Just change the board on my Sermoon D1 with the Creality E3 Free Run. When I try homing, get error :

Unable to read tmc uart 'stepper_z' register IFCNT Once the underlying issue is corrected, use the FIRMWARE_RESTART command to reset the firmware, reload the config, and restart the host software. Printer is shutdown

The config file looks ok ... somebody can help ?

change this if you need more or less extrusion

read E from pause macro

{% set E = printer["gcode_macro PAUSE"].extrude|float %}

set park positon for x and y

default is your max posion from your printer.cfg

{% set x_park = printer.toolhead.axis_maximum.x|float - 5.0 %} {% set y_park = printer.toolhead.axis_maximum.y|float - 5.0 %}

calculate save lift position

{% set max_z = printer.toolhead.axis_maximum.z|float %} {% set act_z = printer.toolhead.position.z|float %} {% if act_z < (max_z - 2.0) %} {% set z_safe = 2.0 %} {% else %} {% set z_safe = max_z - act_z %} {% endif %}
