Describe your issue:

By calling the two macros below, I am trying to move the nozzle to the bed after the tool head parks when a PAUSE command in initiated. Then raise the nozzle to a safe height on RESUME. The _z_to_resume macro below will result with the following error shown in the console, "Unable to parse move ā€˜G1 Zā€™ ".

I assume the variable z_pos_at_pause is not being set with the object, but I do not understand why. Can you help me understand why I am receiving this error?

[gcode_macro _z_to_bed]  # get Z axis position at end of PAUSE then move nozzle to Z0.00 to prevent nozzle oozing while paused
gcode:
  {% set z_pos_at_pause = printer.toolhead.position.z|float %}  # get Z axis position at end of PAUSE then set to z_pos_at_pause
  G1 Z0

[gcode_macro _z_to_resume]  # move nozzle from bed to safe height to RESUME 
gcode:
  G1 Z{z_pos_at_pause}

I found SET_GCODE_VARIABLE must be used when using a value between macros.
