There's no big difference in values so I just set it to default 1.75mm and multiplier 1.

If enable auto cooling is checked then make sure Min print speed isn't something crazy. It should be 5-10mm/s by default. But if it comes on at the smallest layers then this might be kicking in. If you have a fast speed there it might do what you are describing.

I don't know if this even applies to you but it could be something to check.

The 1.68 and .7 came from Solidoodle's default settings I don't know why. But I think it's not the cause.

The fast forward thing happens exactly when it's at the middle and about to do the upper downward direction Arc.

I was curious though about your extrusion multiplier at 70% with a filament diameter of 1.68. Have you run the extruder calibration yet to set your extruder steps/mm?

But it helps to have it right here rather than two steps of downloading and opening file.

I'm printing Pixil Bit's Cube part from http://www.thingiverse.com/thing:120128
It prints perfectly, but whenever it reach the middle part it starts to print super fast, it's like suddenly someone pressed the Fast-Forward button. I've printed 3 times it always fail exactly at the same point. See attached pic, they only differ in height because I pressed the Kill Job different timings.

At first I thought it's detecting the upper curve as 'Bridges' so I sliced it again with my bridges speed at 30mm/s but same thing happens.

My Slic3r settings is 0.1mm see attached GCODE.

Export and upload your slic3r settings
