I am trying to print an arc like object that I need to print supports for. I do not feel that I need to print a raft under it and the bottom is also smoother if it is directly on the bed.
I have set Skeinforge Raft module so that the raft and interface layer counts are zero. Normally my first layer starts at Z=0.2 mm, but for whatever reason with Raft doing the supports the first layer starts at Z=0.6 mm (with layer height being 0.4 mm). This causes the filament not to stick to the bed and cause the print to fail.
I think the Raft module thinks there should be a raft layer at Z=0.2, so it starts the actual print at one layer higher. However I have seen people being instructed to tell Raft make a support with 0 raft/interface layers.
I could just try enabling raft/interface layers, but I am interested in knowing the real reason behind this problem...
What parameters should I tweak in order to be able to print supports properly the way I want?
