Huge printing problem

#1

Hello all.
I made actualizations Moai 130 with all soft and hardware and this is result, lost all details, visible printing lines like on FDM :frowning::frowning:


I upgraded
CURA 3.5.1
MeshMixer 3.5
firmware of Moai 1.18 (also printer menu setup changed for 1.18)
All soft is setup according to manuals available at wiki.peopoly.net
I tried print 0,02 and 0,04 profiles and lso with changing position of model.
I used hi temp resin, in my room is 25 celsius
And before this actualizations my print looks like this:

If someone help me I will be much than happy because i need printer for my work in www.dungeonscenery.com

for hi-temp resin, it’s printed at 51 laser power
from the picture and the information you had given i’m sure that the lost of details is due to over-cured resin

drop the laser power to 50, and try to slice the model with asura this time
we will always be here for you, so don’t worry, we get that it is very frustrated some times

Is the model hollowed and properly vented?

How do you post-process the print?

this problem is not from hollowing or post processing. huge defects on model cant be from post processing. btw i try both with hollow and without = same result

So far this printer has been a joke, been trying to level it for about 2 weeks now and i still cant print the 4 cylinders test correctly.

To me, this looks like the galvos might be vibrating, effectively creating an out-of-focus beam. It might be caused by electromagnetic interference or a faulty circuit.

It might be possible to verify or reject this theory by visually inspecting the beam.

  • Place a piece of white paper in a dry vat.
  • Set the Laser Power to about 20 or 30, so that the beam is easily visible but not too bright.
  • Run a slow program, such as the galvo calibration test file.
  • Try to visual verify that the laser forms a very sharp point on the paper.

Whether or not these vibrations would be visible to the naked eye, I can’t predict, because it does seem as if the vibrations would be quite small. However, this is where I would start my diagnoses. Perhaps by removing the build platform armature, and removing the top plexiglas of the enclosure, you could project the laser to a surface much further away, which would enable you to see small angular changes more easily.

Those are my thoughts, anyway. Hope it helps.
