[random gaps on top layers / Cura 2.6, Ultimaker 3]

The solution for this one as well was, that the meshes we got for printing had inner faces and vertices. This apparently leads to very random behaviour by Cura, where the layer preview looks neat and regular, but the print isn't.

The solution was, that the meshes we got had inner faces and vertices. D'oh.

[random gaps on top layers / Cura 2.6, Ultimaker 3]

I've got some trouble with our Ultimaker 3 - in the print below, I had three kinds of cylinders and I had cloned each one three times, leaving the arrangement of all twelve pieces on the print plate to Cura. The result is, that randomly two of the cylinders are developing weird patterns while the rest is fine:

Is there any explanation for this behaviour? Note that this print is not finished yet, I'll post a picture of the final result tomorrow.

[Gaps on circular infill / top layer pattern]

Hi,

I'm having some trouble with gaps forming when I use a circular top layer pattern and 100% infill, using Cura 2.6 and an Ultimaker 3.

Does anybody have any idea how this happens and what to do against it?

[Acessing the API fails with curl - what am I doing wrong?]

When I access /api/v1/auth/verify using Firefox, that works fine.

When I create a curl request from that using the Firefox debugger that works fine:

 

[me@machine]$ curl "http://xxx.xxx.xxx.xxx/api/v1/auth/verify" -H "Host: xxx.xxx.xxx.xxx" -H "User-Agent: Mozilla/5.0 (Windows NT 10.) Gecko/20100101 Firefox/45.0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" -H "Accept-Language: de,en-US;q=0.7,en;q=0.3" --compressed -H "Authorization: Digest username=""6384f43f0e8aef0e024949b01fe67ba3"", realm=""Jedi-API"", nonce=""dcf0ed0acc248b6918bd25bef863996f"", uri=""/api/v1/auth/verify"", response=""e39ef5c9445ee93a237244dbf2e50aa8"", qop=auth, nc=00000007, cnonce=""87d281d69398db60""" -H "Connection: keep-alive" -H "Cache-Control: max-age=0"{"message": "ok"}

 

When I try to use curl with the same credentials and basic auth it fails:
