About dualstrusion, am currently modding my printers for that, so I could help for testing early version.
Printing a multi-material part is based on having 2 STLs placed relatively to each other.
And the T0/T1 switch allows to have extruder1 for STL1 and extruder2 for STL2.
So, jonathan, in the mean time of having the code ready, would it be possible to have a script to merge 2 STLs, layer by layer, and adding T0/T1 when switching between STL same slice ?
Perhaps such a script exists (A gcode merger tracking layer change), it would be a useful waiting room, doctor !
Please understand, KS (pro) is so good, that I can't came back to s...3. to print a multi!
