I've had xyz filament come with bubbles in the filament. It could also be a bad batch

I'm wondering if it might be temperature related. Black can be tricky to print at the best of times, this stuff maybe needs a lower extruder temp.
What extruder temp are you using ?

I will upload a picture of what it happening if I can ever get one to load.

My prints were a mess, looked like someone had taken a cheese grater to them.
I put the ABS in an airing cupboard overnight and it printed fine after that.
I now store all my filament in these .... http://www.thingiverse.com/thing:457359

This happens to me when the speed is set lower. I think my extrusion rate may be too much. Either that or I have a moisture problem as well. Sometimes you see these small tiny chunks that come out of the extruder. Temp change doesn't really help this.

Do you mean the layers are seperating?

A picture would help as well as setttingd like temp on extruder and bed. Thr speeds your printing at and so fourth.  Its alwsys good to give as much info as possible when looking for help with problems and ad the old saying goes a picture is worth a thousand words.

You could try storing the filament in an air tight container with rice or other dissicant.

In the future never open filament till you want to use it, and store open filament in an air tight container with something to absorb moisture just in case.

You could also be printing too hot but you would know by the smell

I did a few test prints and it seemed to work just fine, but whenever I print larger objects the print seems to bubble, any ideas?
Thanks,
