Thanks gr5. I have spent considerable time trying to get the printed part to come out with a nice smooth surface between the part and the support material with two different materials (ABS with Hydrofill; ABS with HIPS). The transition layers are now looking pretty good, but now I'm having issues with the rest of the piece (warping, oozing, curling, etc). I get one issue fixed and another develops. *sheesh* I have spent a bit too much time and I need to go back to printing both part and support with the same material just to get moving ahead again. I'll definitely come back to this issue and I'll post the solution when/if I get it. I appreciate your help.
Regards.
