fine-tuned the alignment of my X-Y gantry and properly lubed all the things. I did some movement tests at 400mm/s and didn't get any missed steps. (not extruding, of course). Now trying to get the retraction dialed in well. Not too bad so far.

Still struggling to get good adhesion with Taulman 618. My bed is unheated so I have tried the following: Blue tape, cast nylon, garolite (unmodified), and garolite sanded lightly with 100 grit sand paper.  The part I'm printing wants to warp significantly and has peeled off everything but the sanded garolite. However, I couldn't get the part off the sanded garolite without destroying it :( I guess I might try sanding the other side of the sheet with a VERY fine paper (>600 grit) and see if that does anything.
