Not to G28 or QGL every time from start macro if its already done.

Buurman · January 22, 2023

So I want to see if its possible to check the status of G28 and QGL if its already done in previous print for example.

If its already done, skip it and continue, this can save some time since the TAP needs to cool off, etc for this.

I have found that it seems possible, but wanted to make sure I am following the right path here, maybe someone is already doing this today...

So I found this:

[gcode_macro G32]
gcode:
    STATUS_HOMING

    
    # 1 ----- HOMING ------------------------------------------
    # Home if not already homed and park the head near the center front
    {% if not 'xyz' in printer.toolhead.homed_axes %}
        G28
    {% endif %}

    # 4 ----- QUAD GANTRY LEVELING -----------------------------
    {% if printer.quad_gantry_level.applied|lower == 'false' %}
        {% if V %}
            RESPOND MSG="QGL..."
        {% endif %}
        QUAD_GANTRY_LEVEL
    {% endif %}

So it seems if I would call a G32 (I now dont in my start macro, I call a separate G28 and a QGL) then this would check its status, and skip if its still valid.

Yet, what does this STATUS_HOMING do? I cant call this manually, is this a seperate macro I dont have?

I have seen it in more macro's out there, yet cant really found out how to get it to work, I havent called it from this macro yet, just manually tried it, gives an unknown command.

Would be cool to find out and be able to skip it, running multiple prints, it can save some time for sure, since I heat up the nozzle first, scrub it, then cool it off again for a new/clean G28/QGL. And like this I should be able to skip all of that, and scrub and print. TAP starts to annoy me a bit on the cold probing (something happened to the smilies)

STATUS_HOMING

i guess it is for the LED's (see here a part of my led.cfg)

[gcode_macro status_homing]
gcode:
    STOP_LED_EFFECTS
    SET_LED_EFFECT EFFECT=sb_logo_homing
    SET_LED_EFFECT EFFECT=set_nozzle_leds

I do the check if already homed in my unload/load Filament macro for example and it works fine and safes time

.
.
{% if printer.toolhead.homed_axes != 'xyz' %}    
      M117 Homing...
      STATUS_HOMING
      G28                                                                       ; Homing
{% endif %}
.
.

ok, strange name for a led effect macro, guess I can leave it out then, thanks a lot!

Ah, yes, its from a LED mod:

Nice find. I may look into using this after I get my Stealthburner and TAP installed.

Buurman · January 22, 2023

I have added these two parts to my start macro but still they take place every time.

So I expect that the requested xyz are not in the place they look for it... no idea how to find out though..

    # 1 ----- HOMING ------------------------------------------
    # Home if not already homed and park the head near the center front
    {% if not 'xyz' in printer.toolhead.homed_axes %}
        G28
    {% endif %}

    # 4 ----- QUAD GANTRY LEVELING -----------------------------
    {% if printer.quad_gantry_level.applied|lower == 'false' %}
        {% if V %}
            RESPOND MSG="QGL..."
        {% endif %}
        QUAD_GANTRY_LEVEL
    {% endif %}

Moin,

Here's what I have for conditional homing:

[gcode_macro _CG28]
description: Conditional homing
gcode:
  {% if "xyz" not in printer.toolhead.homed_axes %}
    G28 { rawparams }
  {% endif %}


[gcode_macro G28]
description: G28 homing with SB LED status
rename_existing: G2828
gcode:
  LED_HOMING
  RESPOND MSG="Homing"
  G2828 { rawparams }
  UPDATE_DELAYED_GCODE ID=_CLEAR_DISPLAY DURATION=1
  LED_STANDBY

So in my print_start, I only home if it's needed. Being a Trident I z_tilt_adjust instead of QGL, but I don't care if it's been done or not--I just run it every time.

geekandi · January 23, 2023

some good things here though requiring some other macros to be set, which I don't use. Short and sweet, no other macros, no extraneous messages on console (though that can come in handy).

Trident:

[homing_override]
axes: z
set_position_z: 0
gcode:
   G90
   G0 Z5 F600
   {% if not 'xy' in printer.toolhead.homed_axes %}
     G28 X Y
   {% endif %}

   G0 X150 Y150 F9000
   G28 Z
   G0 Z10 F1800
   G0 X150 Y150 Z30 F5000

[gcode_macro Z_TILT_ADJUST]
rename_existing: _Z_TILT_ADJUST
description: Conditional Z_TILT_ADJUST
gcode:
    {% if printer.z_tilt.applied == False %}
      _Z_TILT_ADJUST {% for p in params
            %}{'%s=%s ' % (p, params[p])}{%
           endfor %}
      G28 Z0
    {% endif %}

V2.4:

[homing_override]
axes: z
set_position_z: 0
gcode:
   G90
   G0 Z5 F600
   {% if not 'xy' in printer.toolhead.homed_axes %}
     G28 X Y
   {% endif %}
   G0 X150 Y150 F10000
   G28 Z
   G0 Z10 F1800
   G0 X150 Y150 Z30 F5000

[gcode_macro QUAD_GANTRY_LEVEL]
rename_existing: _QUAD_GANTRY_LEVEL
gcode:
    {% if printer.quad_gantry_level.applied == False %}
      _QUAD_GANTRY_LEVEL {% for p in params
              %}{'%s=%s ' % (p, params[p])}{%
              endfor %}
    {% endif %}

@geekandi the macros you postet are for TAP I guess as homing Z is in the center of the bed (in this case 300mm) and I think the 2nd "G0 X150 Y150 Z30 F5000" is not neccessary?

This is what I used pre-Tap and post-Tap - works just dandy - sharing what works for me, YMMV

Macro for checking...

Excellent though I would always do a Z check regardless because of offsets based on temps and such.

I use [homing_override] for my junk on the XYZ homing as I posted above.

The Z axis also goes home to [gcode_macro_CQGL]

[gcode_macro _CQGL]
; QGL if not already done.
gcode: {% if printer.quad_gantry_level.applied == False %}
	   _CG28
	   M118 QUAD GANTRY LEVEL
	   status_leveling
       QUAD_GANTRY_LEVEL
	   status_homing
	   G28 Z
       {% endif %}
	status_ready
	M118 QGL DONE

[gcode_macro _CG28] and [gcode_macro _CQGL] are registered in print_start and executed after warmup
