Well after a few long evenings in the garage redesigning the Z axis and working through various problems I finally got back into CAMBAM to generate some 2D tests - I'm a very pleased with the results thus far. Precision seems to pretty good without much tweaking and all axisis are functioning properly!

Been a while, but I'm finally getting motivated again to keep the project moving - had to take care of a few "honey-dos" prior to moving forward.
Found a older computer (c.2004, Celeron 2.6ghz put a clean copy of XP) to push the GCode - will probably do the designing one of my non-garage machines since this is just barely fast enough that I don't take my sledge hammer to it.
Got the power supply (Goodwill, thank you!) all wired up to the GRBL shield, flashed Arduino with 0.8 GRBL and have the X & Y axisis running great. No binding or hang-ups. Only issue thus far is with the anti-backlash springs, which I don't think are quite big enough. They are getting hung-up on the treads, so I left them out for now.
Put some good time in last night with the Z axis - the more I work with this particular design, the more I realize that it is extremely easy for the small errors to add up into a machine that may not have the accuracy I'd like, especially when I don't have a lot of precision tools to build. A learning experience before moving on to bigger and better.

Very excited to actually get a motor mounted (this week?)
