Which type of extrusion problem? I'm a novice in 3D printing. I have a Lulzbot Kittaz 3D printer with a hexagonal hot end of 0.35&nbsp;mm. I have printed a test subject, and while I was printing I encountered this extrusion problem. I'm using ABS with 230&nbsp;°C hot end temperature and 85&nbsp;°C bed temperature. What kind of problem is this and how should I rectify it?

I took this photo when the printer printed the first layer:
It looks like you are not extruding at the correct rate. I would check your slicer settings for nozzle and filament size. Also check and calibrate for your filament diameter.

It looks like you could be getting better adhesion too. Lulzbot recommends a 110C bed temperature. That might help. (lulzbot.com/store/filament/abs under specifications)

These are some good resources to troubleshoot prints,
