Try looking for a setting called Z-Lift, it makes the Z axis drop out of the way when the head needs to move without printing. This keeps the head from scraping off the already printed filament. This does not work well if you have a lot of backlash in your z axis. I use a setting of .3 for z-lift. I think the setting may be in the advanced section for the extruder settings (last tab?)

unfortunately that's an option to print an entire object and then move onto the next .. it not what I am looking for but may well solve the problem if I had 4 identical objects loaded as 4 models. I am using a single model containing 2 pairs of objects so I would have to change my models.
I think the way skeinforge approaches it is a far better solution than just printing the perimeter of an object then leaving it and moving on especially when there is no Z lift to cross the perimeter.

I have never used this setting, but in Slic3r Config > Print Settings > Output Options there is a checkbox for 'complete individual objects'. I am wondering if this will help by having it finish each object individually.

I have been printing 50 cases for a small bit of electronics I have made and to speed up the process I modelled 2 case tops and 2 case bottoms on the bed, printing 4 objects at once. actually ... did a timelapse with this and you can see the method here..

It does each area individually and the infill with the perimeter.. the part has a good chance of staying stuck.
So I have never had issues with sticking using skeinforge.

Then last week changed to the new repetier host and slic3r and have been printing fine with single objects, but this morning attempted to reslice this model and give it a go with slic3r .. its totally impossible, gave up after an hour or so and have gone back to skeinforge.
The problem with slic3r is it wants to print the perimeters of the 4 objects first leaving 4 fragile little circles on the bed, then rush back over them with no bed retraction and print the infill, of course running the extruder back over these tiny bits of filament drags them off the bed .. every ... single ... time.
I see many are using slic3r, is there a setting I am missing somewhere to get the method to change or some way to stop it ripping a small layer off ?
