Folks, Ive been trying dual printing for a change.... but hitting some issues.

I'm running Saolfish firmware and S3D as the slicer.
managed to calibrate the tool offset by hand since Sf seems to have a bug which prevents makerware calibration strips from working.
so anyway...

I create a Dual printing in S3D (using the wizard) all is well until the second head starts to print the ooze shield, then it extrudes a giant blob before starting to print.
It's like it's clearing itself...

But I already have start g-code that runs a strip accross the front of the build plate.
I also have a skirt at 10mm out and ooze shield at 5mm out, so can'r figure it out....

This might be an S3d issue ?
