Titan Aero offsets

  • I have my Titan Aero setup. I have the exact same mount on a different Ender 3 but with a SKR E3 mini v1.2.

    Using the same offsets that work on the other machine, my offsets should be:

    G31 P25 X21 Y-44 Z0

    When home all after startup, the probe is way off the front edge.

    Again, here are my files:

    retractprobe.g homez.g homey.g homex.g homeall.g deployprobe.g config.g

    I'm not sure exactly what you mean.

    In the homeall.g you can position the print head where ever you want at the end. If the homed position leaves the probe off the bed, but it didn't previously, perhaps the homing behaviour before was different?

    The G31 offset is just telling the firmware where the probe is in relation to the nozzle. It doesn't affect where the probe is positioned after homing.

    You can measure your probe offsets using these guide steps:

    If you want to position the probe after homing Z

    G1 S1 X-269 Y-261 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
    G1 X5 Y5 F6000          ; go back a few mm
    G1 S1 X-269 Y-261 F360  ; move slowly to X and Y axis endstops once more (second pass)
    G90                     ; absolute positioning
    G1 X51 Y20 F6000        ; go to first bed probe point and home Z
    G30                     ; home Z by probing the bed

    Add a G1 X Y move after the G30 that puts the print head where you want it.

    Also, the G1 X Y move BEFORE the G30 should be changed so that it places your probe at the center of the bed. Maybe I totally misunderstood you at first and that's actually what you were referring to?
