Z layers not printing properly #69

Closed TheAussieTinker closed 1 year ago

TheAussieTinker commented 1 year ago

On the left is printed on my prusa mk3 and looks as it should on the right is printed on my elegoo Neptune 3. It seems like the z axis has squished many layers into one of the middle layers before continuing, resulting in this weird seam and a piece that has incorrect dimensions. My setup:

What I have tried:

How should I fix this?

hi @TheAussieTinker

  1. Check the grid value in the leveling interface to rule out whether the grid data deviation is too large? (Usually we control the deviation between the left and right values of the grid within ±0.5 is best.) If you encounter the problem of hot bed tilt, you can use the following method to debug: https://youtu.be/MRsDb_wC8S8

  2. Manually move the Z-axis up and down to rule out whether the stepper motor loses steps because of moving resistance? If so, the Z-pulley needs to be properly adjusted according to the following method: Neptune3-Leveling Issue Solutions.pdf

  3. You can also increase the Z-axis drive current appropriately, adjust the position of the potentiometer as shown in the figure, decrease clockwise, increase counterclockwise, and fine-tune appropriately (pay attention to turn off the power operation). image

I think it may be an issue with the V1_1.05-beta firmware working with octoprint. I used a version of the firmware modified by Michael Lee and The Feral Engineer. I have positive results so far but I am going to do some more tests before I post about it.

FIXED: This was an issue with the firmware interfacing with octoprint. In order to resolve this issue I built a version of marlin from The Feral Engineer (link below) and commented out the mods he added. I then flashed the firmware onto the printer, releveled the bed, and it was good to go. Working properly with octoprint

I used the source code from the ZNP_F401_Marlin-Beta folder https://github.com/TheFeralEngineer/Neptune_3
