  1. You should add M420 S command after G28 to Start G-code. According to Marlin docs , G28 command disables bed leveling by default. Alternatively, you can change the RESTORE_LEVELING_AFTER_G28 value to true in firmware.

  2. Now that you have leveled the bed you are ready to start printing. To enable leveling for printing, you need to add G-code G29 directly after G28 in your start G-code of your slicer.

  3. As it turns out, my Z-axis carriage mount to the X-axis was bent, causing the nozzle to touch the bed before the proble could get a chance to detect anything.

  4. Fade Height is used to specify the height above the bed at which the printer should stop fading the bed leveling correction. Bed leveling is gradually decreasing with each successive layer until fade height is reached.

  5. I would go with 60 degrees on the bed and check the bed levelling. You shouldn't be having a problem with PLA if the levelling is fine unless your filament has gone bad.

  6. ABL stands for Automatic Bed Leveling UBL stands for Unified Bed Leveling Level the bed? A level bed (twisting knobs under the bed), or a surface that is exactly followed by the nozzle is a prime requisite for 3D…

  7. Bed Visualizer shows the mesh leveling area regardless of the bed size, that is good because it provides a good level of detail if the mesh area is very small compared to the bed size.

  8. You are correct to define the constants AUTO_BED_LEVELING_LINEAR and Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN , be sure to define the following also: and Note that 300 should be the distance from nozzle to bed after homing.

  9. Auto bed leveling requires some settings (constants) in the configuration of your Marlin firmware. It is recommended to read about the implementation of automatic bed leveling first.

  11. From the image and your observations: Hints to a different problem than your posed question. Depending on what type of levelling mesh and the amount of probing points you use, the bed surface will be replicated.

  12. The problem with the Tevo Tornado design is that the design is as such that the Z-axis is powered by a single stepper (under the assumption that you have not added a second Z stepper).

  13. That depends on the bed plate and how it is mounted in the printer, and how well you are able build a square frame. Is the bed a thick slab of machined aluminium, chances are it is very flat.

  14. The gaps are, because the nozzle is to far from the bed at this point. It may sound like a big deal, but actually this is not leveling alone, but it looks like the bed is not a perfect plane/perfectly flat.

  15. I think your issue is bed leveling. I recently got my Anet A8 and the biggest kill for my print quality is bed leveling. If its too far from the nozzle, I get something like your picture.

  16. Proper leveling using plain "A4" or "Letter" paper is recommended. Level the bed by first homing all axes, then level each corner and at mid-span.

  17. Dirt. It was dirt. Most likely. Apparently the machine establishes bed level with a sensor, and I might be wrong, but I think the ET4 monitors capacitance as a means to notice how far the nozzle is from the bed.

  18. 3D printers like the German Reprap (see image) already uses a photosensor for homing the axes. The trick will be leveling the leveling sensors.

  19. If the nozzle is touching the bed, you need to further screw down the bed. If the springs under the screws are already fully compressed, you cannot lower the bed further and you will need to move the Z-endstop up.

  20. Having moved the probe up and down gently to ensure it wasn't catching, I restarted the machine and have not been troubled since.
