[Top layer invisible in Cura]

I've been testing a model in Cura just to see how long it will take to print and how much filament.  I have been having a weird issue though.

When I have rafts enabled, the top layer(s) doesn't show up in layer view.

With raft disabled, everything looks peachy.

I haven't had a chance to try printing the model yet.  Is this just a weird visual bug/glitch?

See pics below

UPDATE:

I tried printing the file with the raft and it printed just fine. As far as I can see, it's just a visual bug.

[Cura gcode start]

@atooltoscream

Sorry, but can you share some more informations?

- Which printer profile do you use within Cura?

- How does your start gcode looks like?

A short google search found this example profile for the Micro 3D

...and the Airwolf FAQ mentions a "recommended profile" for Cura "provided on the USB drive received with your printer"...

Have you tried this already?

Anyway... it's just my personal thought, but i assume the Cura developers can only make a guess about your printer(s). Perhaps the linked sites are a better place to ask...?

 

Thanks for the response. For my M3D I'm using the example profile that you linked. For the Airwolf, I set Cura up per their instructions in the user manual. I loaded the ABS profile from the Airwolf USB drive and the only things I changed were certain parameters (fill, shells, etc.). I didn't change anything about the Start/End G-code.

My workaround so far has been to print everything with a raft or brim so the printer is laying down filament by the time it gets to the actual part. I'll paste the G-code start below:

M117 HD Printing...

[Cura gcode start]

I have a 3d printer at home (M3D) and we just got an Airwolf HD2x where I work.

I use Cura for slicing and gcode creation in both cases, 15.04 for my printer and 15.04.3 for our work printer. My question is, why do my parts perform a gradual approach when a print starts? What I mean is, the print head will start along the path of the first bead but it will take anywhere from a few mm of travel to a few inches of travel before the print head is close enough to the surface to start laying down filament. So basically, my prints have a line of missing material.

Is there a setting in Cura that makes it behave this way?

Thank you so much
