Auto-home attempt #1

  • Z-axis movement works
  • X-axis - moved to the right but not left
  • Y-axis - the bed moved back.

Diagnosis: motor wired wrong?

  • Motor wires disconnected and assembled.

Auto-home attempt #2

  • X-axis no move?
    • Problem was the switch for x-axis was disconnected. Fixed.

Auto-home attempt #3

  • Success!

Auto-home attempt #4

  • Verified success!

Bed-leveling Corner of Origin:

  • All wheels returned to starting position.
  • Attempted leveling leaves the bed not quite reaching the extruder.
    • Discord: Z-limit switch might be too high.
      • Picture took. Discord: lower it a bit.
        • Also suggested: Print out adjustable screw probe
    • Attempting solution to problem:
      • Measure: 3.4, Took picture.
      • Loosen z-limit and lower a little bit.
        • Measure: 3.3, took picture.
        • See next section for success or fail?

Bed-leveling Corner of Origin. Take #2

  • Auto-home success! No crashing.

  • All wheels returned to starting position.

  • Attempted leveling leaves the bed nearly reaching the extruder. Better than last time? Picture took.

  • Someone offered to help. Following his instruction.

    • Centered the extruder in the center of the bed.
    • Cut off the z-switch peninsula.
    • Uninstall the z-switch.
    • Have the extruder hit the bed(with paper). Made sure there's a drag on the paper.
    • Reinstall the z-switch, making sure that the extruder bar hit the z-switch.
    • Watch: https://www.youtube.com/watch?v=5eqTmb01cBk
    • Auto-home.
    • Paper leveled x2
    • Raise temperature to 205 nozzle, 60 bed.
    • Acquire bed test gcode.
    • Init TF. card
    • Load bed test.
    • Print. Took picture. Disaster. Mostly too high.

    Printing test & bed leveling calibration, attempt #2. See Bed-leveling effort from yesterday.

    • Auto-home. Calibration with paper, exclusively raising the bed.
    • Test with bed level model.
    • Print. Took picture. Improvement from yesterday. Still isn't laying the lines between square properly.

    Calibration and test #3

    • Repeat the last section.
      • Autohome failed to initialize. Got error: Too far! Took picture.
      • Tried autohome again, this time, it returned to origin. Still outputting the error.
      • Printed. Photo taken. Seems to haven't hit the bed?
      • Thought: The error message was probably from when the clip got in the way of the bed movement.

    Calibration and test #4

    • Got rid of the error by power cycling. Autohome. Calibrated right bottom corner(next to the control panel) only.
    • Print. Photo taken. Right bottom corner look sgood, as did center. Left is OKish. Left bottom and top bottom are rubbish.

    Calibration and test #5

    • Calibrated again. This time left bottom corner.
    • Print. Photo taken. All the square except the top left is near perfect. The line is almost good on the left side. Right side seems perfect.

    Calibration and test #6

    • Calibrate on the top left corner.
    • Print. Photo taken. Everything's basically perfect except the bottom left.

    Calibration and test #7

    • Calibrate the bottom left corner.
    • Aborted print to stop wasting time. Picture taken. Incidentally bit harder to remove the aborted print outline than a full print one.

    Calibration and test #8

    • Calibrate again, this time across all the bed level
    • INCORRECT BULLET POINT BELOW
      • Noticed scratching. Aborted print. Figured out what the musical noise were. The extruder was hitting the bed.
    • Photo: Actually, I am wrong. It's just very faint filament.
