Solved digging nozzle across build plate.

[inner glade]

So I already messed up my build plate and I’m not even past tuning my Merc. I ran home , then z_tilt and the probe-calibrate. Then tried to run the flow test from orca. The nozzle literally is draging to the point of scratching all the texture off the build plate wherever it goes. What am I don’t wrong or missing? Let me know if I need to post anything.

But I was getting perfect first layers. Not sure what changed.

What probe?

And got a Pic of the mesh?

I suppose you ran a bed mesh. Also, is it triple z?

[inner glade]

It’s triple Z. I’ll post the bed mesh and I’m using a BLTouch

Why are you running a toolhead board but still have a million wires? 🤔

[inner glade]

i Just havent shortened the wires for the extruder. The others just need to be ziptied to the toolhead. I am trying to wait till everything is fully functional before the final tidying up.

That should be flatter. I have the 8mm 400x400 bed from Fabreeko.

Y extrusions not aligned might also be an issue

What's the proba accuracy

[inner glade]

0.0125

[quaint vigil]

PROBE_ACCURACY X=200 Y=200 PROBE_COUNT=15

[inner glade]

Is that a command?

[inner glade]

I figured out what you were asking.

Ok, it's not the probe

Fixing a Wonky Trident Bed Mesh
Y extrusions that are not in plane with each other result in an odd mesh. It will appear straight accross the front of the bed and the back will have a slant.

This is because a trident only levels the bed from 3 points near the z drives so it does not have the means to correct z height in the back corners.

Before making any adjustments place printer in its permanent location and ensure the surface it's on is flat and solid.

The fix is to adjust one corner on one Y extrusion to compensate. With a mesh active, hover over the two back corner points and see the difference in Z height between them. The difference between them is the amount you need to move a corner by.

One side on the back of the mesh will be red. (It will look like the bed is too high in that area) On the side that is red you will adjust the front corner down by the amount you measured earlier in the mesh. This is done by loosening the screw for the blind joint on the front of the printer in the vertical extrusion. Move that side of the Y extrusion down.

Leave the printer powered and leveled while making these adjustments so you can quickly run a Z-Tilt and a bed mesh and see if further adjustment is required.

This image shows an example of the wonky mesh and indicates the two points that should be measured:

Bad ass. Where is that I would like to see the images of a wonky mesh

ok, ill try this when i get home. Happen to know the Gcode command to park the toolhead in the back right corner at the end of the print. Something like Z hop 10, and then move to like 380,380,

[quaint vigil]

Asking if I know gcode to do that?

[quaint vigil]

[gcode_macro PARK_TOOLHEAD]
gcode:
    # Get current position
    SAVE_GCODE_STATE NAME=parking_state
    # Check if Z is below max Z height, if so, move up 10mm
    {% if printer.toolhead.position.z + 10 <= printer.configfile.config["stepper_z"]["position_max"] %}
      G91 ; Relative positioning
      G1 Z10 F600 ; Raise Z by 10mm
      G90 ; Absolute positioning
    {% endif %}
    # Move to the back right corner
    G1 X{printer.configfile.config["stepper_x"]["position_max"]} Y{printer.configfile.config["stepper_y"]["position_max"]} F6000
    # Restore the initial position and settings
    RESTORE_GCODE_STATE NAME=parking_state

Your thje best

[inner glade]

For some reason this doesn’t work for me.

[quaint vigil]

What's the issue?

[inner glade]

I’ll type it out when I get home. It couldn’t resolve something in the code.
