I am having some very odd behavior from the Titan after I upgraded. I am using the original stepper motor and after doing the calcs I should be at about 836 steps. I am already at 860 steps and getting very fine lines for the first layer, but it should be over-extruding like mad at this point. I am using RC6 and Alex's S3D profile, but no matter what I seem to try it stays the same. I started with a z-bed position of .1 and am now down to -.104, but the nozzle does not seem to be getting any closer to the bed. Thoughts?
