One thing I haven't heard anyone bringing up is a possible issue with retraction settings. If you're printing with retraction, try turning it off for a test print. It could be that adding the support structures adds that many more retractions to the print, increasing the chance of extrusion failure. No QIDI printer here, but I thought I'd throw that into the mix of possibilities.

I just tried it again with these settings:

But still failure, as soon as it reaches the supports the build plate and the extruder gradually get separated by a centimeter or so. I don't know what to do. So as soon as the print reaches the part where it will start the support structures: this part:

The extruder and build plate are not closely together (shown in the video)Last edited by fontseeker; 09-21-2016 at 08:24 PM.

Thanks for the information. It sounds like your software is generating G-Code that has some really weird settings for the support as I don't see anything in your config that would make me think your print would mess up like the video.
I've never really encountered anything like that in S3D and hope someone else more knowledgeable in that software may be able to assist.

Halfway through the print, a gap of air between the extruder and the actual print is present. I don't know why:
My settings are:Filament: PLA
Extruding temp: 220C
Build Plate temp: 40C
Layer height: 0.2mm
Shells: 2
Extruding speed: 40
Speed while extruding: 40mm/s
Speed while moving: 60mm/s
I use Makerware as my slicer

Also, in this picture there are empty spots in the first layer? Could that be an issue?

the empty spots are because at that point the extruder is too close to the build plate to extrude. ie, the build plate is not level.
Now this will cause a build up of molten filament in the extruder the will change how it prints the next bit of the layer.
In other words just having the bit of the bed not level could well effect the entire print.
Apart from your print temp being a little high for pla (try 210), settings are fine.
But your build plate is definitely not level.
Please explain to me how to...
