Top Layer Fail, help

Jaco 2017-11-10 08:45:37 UTC #1

Hi, I have printed a few pieces now where the top layer fails, meaning, it prints incomplete. I have tried to increase the outline but that did not change. I remember on Vox 1 you could change the top layer, but I cannot find it on Vox 2.

Same problem on 1.5.11 bottom prints correctly, flat tops are not printing at all. Looking at the gcode it doesn’t seem to generate anything at all despite a clearly flat top!

I printed a bearing ring through the night and the same thing, tops are not printing…

@Jaco I have the same result as you are showing I think there is a bug in the slicer on Vox2

Hi! Which version do you use? For Mac or Windows?
Best regards,

I printed a bearing, downloaded from Thingiverse,(the comments ALL said it prints fine), I used Vox 1 and 2 and both printed them exactly the same, fused and unusable.

I used version 1.14.18 and 1.5.11

@Jaco, please let me know if you used Voxelizer on Windows or Mac.
Best regards,
Emilia

MAC, sorry forgot to answer.

@ewes I’m on a Mac running 10.13.1

@Jaco I’m not surprised about the bearing, reducing parts to voxels has it’s upsides and downsides. Reducing geometry to voxel frequently looses design intent and information. A gap that is less than a voxel width would be labelled as fused. For a type of print where you have a small gap you want maintained you need a different type of slicer.

Hi Jaco, can you send your gcode to our support team ? They will print it and see if it’s workable. By the way, it seems you don’t have proper cooling in place, or there is another problem with extrusion quality - please contact us on livechat or at support@zmorph3d.com, we’ll help.

If balls fuse with bearing due to small gap, just decrease voxel size.

Regarding top infill - we know it happens only on Mac, it’s being investigated.

Przemek, sorry for the delay in response. I think two things happened, The design is dodgy and I did print it succesfully with Voxelizer 2 eventually.
I then printed another design, and will send it throught tonight.
What I did succeed to do is print the same ddesign with both a windows and Mac versions and the windows version prints the tops perfectly.
So the MAC version of Voxelizer is faulty.

Hi!
This is the new Mac version: https://s3.eu-central-1.amazonaws.com/voxelizer-update/internal_releases/voxelizer-v1.5.11-213-g9ff5de.dmg
The top layer issue should be solved. It’s unofficial release, so please, let us know if something doesn’t work properly.
Best regards,
Emilia
