Just finishing the build of me new, own design, dual extruder printer. Based on Reprap, Ramps 1.4, Marlin and of course using Simplify3D.
So far I've managed to get some very good prints off just one extruder and managed to set up my profile to allow me to use the Dual wizard. Now comes the problem.
The dual head nozzels are 54mm appart on the X plane, 0,0 on the Y plane. The Left one is T0 and the Right one T1. The X axis 0,0 is to the Right but home (and the limit switch) is to the Left 240,0. In Marlin I have identified the second extruder as -54mm from the '0' extruder. I have also told Simplify that T1 is -54mm.
So, I set up to print a test cube with the external perimeter at 2 layers and using T0, then I set the infill up but with it using the T1 extruder. What I am expecting is a cube where the outside is one colour and the inner infill another one. What I am getting is that the printer starts to print the base layers in the middle of the bed, but when it comes to changing to the T1 extruder the print head does not shift over, so the infill is printed -54mm away from the base.
What am I doing wrong here ???
