This is my first filament fail.

This is my first filament fail. This is from a roll of orange Filamentprint 1.75mm PLA that I got with my kit from RepRapPro.

What is your experience with this vendor?

Is that a bubble?

I have no idea what is is but it is really thick at that point. I tried cut it at that point and it seems solid.

Its most likely to join and I have seen two, one caused a print fail and I spotted the other one before it was a problem

Yeah this one cause a print to fail it was only two layers in so it wasn’t really a problem although I was confused as to what had happened at first as I didn’t expect this.
