#GQL is perfect, but first layer is grinding in a specific corner [SOLVED]

Just as stated above, the QGL process is going fine, but as soon as I print a large object, when the nozzle gets to the back right corner, I can hear the nozzle scraping. This does not happen at the front of the print, where the layers are normal.

I am using voron tap with the default tolerance for QGL.

are you doing bed mesh leveling, and is that applied properly? and if so, was the bed mesh done after qgl?

thanks @stuck cliff, from what im reading the levelling is not happening, this is my PRINT_START:

[gcode_macro PRINT_START]
gcode:
  #--------------------------------------------------------------------------------------------------------
  #--- read values provided by slicer
  {% set temp_bed     = params.BED|int %}     #*** Required. BED value must be provided by slicer
  {% set temp_hotend  = params.EXTRUDER|int %}  #*** Required. HOTEND value must be provided by slicer
  #
  #--------------------------------------------------------------------------------------------------------
  #--- do the usual stuff
  M190 S{temp_bed}                            #*** Set bed temp and wait
  M109 S150                                   #*** Heat nozzle to 150 and wait
  G32                                         #*** Home all, probe bed, level the gantry and such
  G90                                         #*** Absolute positioning - don't remove
  BED_MESH_PROFILE LOAD=default               #*** Load mesh
  #--------------------------------------------------------------------------------------------------------
  #--- set hotend to the temp provided by the slicer
  M109 S{temp_hotend}                         #*** Set extruder temp and wait
  
  # Gets ready to print by doing a purge line and updating the SB-leds
  SET_DISPLAY_TEXT MSG="Printing..."               # Displays info
  STATUS_PRINTING                                  # Sets SB-leds to printing-mode
  G0 X5 Y4 F10000                      # Moves to starting point
  G0 Z0.4                                          # Raises Z to 0.4
  G91                                              # Incremental positioning 
  G1 X100 E20 F1000                                # Purge line
  G90                                              # Absolut position

It looks like it just loads the profile after levelling the gantry, duh!

That's at least how I do it. Made the mesh profile with gantry leveled. Then when printing, I clear bed mesh, run qgl, and then apply bed mesh.

What was it that fixed it?
