t0 t1 command always switching to the left hotend (klipper)

I'm having the same problem with my DSH servo.

Note: In MainSail v2.4.1, the "variables fix" does not work.

I received errors with this;

# filename: ~/klipper_config/variables.cfg

I had to change it to this;

filename: variables.cfg

Clicking "Extruders" T0 or T1 or "Macros" T0 or T1 always moves the servo to T0.

Setting the angle via "Arm Install" or "Arm Position" with manual angle moves the servo correctly.

Here's my Macros.cfg (for the servo only)

[gcode_macro ARM_INSTALL]
gcode:
  SET_PIN PIN=servo_power VALUE=1                    # Power on servo via relay switch
  SET_SERVO SERVO=extruder ANGLE=90                  # Set servo position to 90 degrees


[gcode_macro SERVO_OFF]
gcode:
  SET_PIN PIN=servo_power VALUE=0                    # Power down servo via relay switch


[gcode_macro ARM_POSITION]
gcode:
  SET_PIN PIN=servo_power VALUE=1                    # Power on servo via relay switch
  {% set serv_angle=params.A|default(0)|float %}
  SET_SERVO SERVO=extruder ANGLE={ serv_angle }      # Move servo arm
  G4 P1500                                           # Allow time to make move
  SET_PIN PIN=servo_power VALUE=0                    # Power down servo via relay switch



[gcode_macro T0]
gcode:
  {% set svv = printer.save_variables.variables %}   # Set svv to point to variable.cfg
  ARM_POSITION A={svv.left_ang}                      # Switch to T0
  {% if "xyz" in printer.toolhead.homed_axes %}
  SET_GCODE_OFFSET X=0      
  SET_GCODE_OFFSET Y=0   
  {% endif %} 
  ACTIVATE_EXTRUDER EXTRUDER=extruder
  G4 P2500
  

[gcode_macro T1]
gcode:
  {% set svv = printer.save_variables.variables %}   # Set svv to point to variable.cfg
  ARM_POSITION A={svv.right_ang}                     # Switch to T1
  {% if "xyz" in printer.toolhead.homed_axes %} 
  SET_GCODE_OFFSET X={svv.x_off}                     # Account for different X offset
  SET_GCODE_OFFSET Y={svv.y_off}                     # Account for different X offset
  {% endif %} 
  ACTIVATE_EXTRUDER EXTRUDER=extruder1
  G4 P2500

what slicer are you using?

I've run into this same issue. For now I've manually changed the macros to have the angles themselves rather than pointing to the variables file, although I'm curious what might be causing the problem.

unfortunately that didn't work as i already figured out to add the save file line to the cofig. i do get movement from the servo but only to center and to one side and i will get extruder already active repone when i use t0

Apologies, the build manual needed an additional step, please see below:
