Portabee 3D printer

I don't have any real problems just some holes and pits in the print; but not throughout just in places (mainly on organic shapes). I do have a cooling fan (although i've jst checked and it appears not to work)....could that be it??

The cooling fan is needed for small parts - if they're not cooled, heat builds up in the part and it melts. The fan is normally off for the first layer and is then turned on for subsequent layers - this needs to be configured in your slicer program if you have a fan that can be controlled.

This (http://reprap.org/wiki/Print_Trouble...ictorial_Guide) is a good guide to print problems but doesn't have much on blobs or pitting :-( I'd guess it's your retract settings which are designed to stop plastic oozing out when moving the print head between printed areas but I'm afraid I don't have much experience with these settings (it's on my list of things to do).
