Putting together my Ox and noticed when I slid the carriage on the 20 x 60 x rails it was tight with the eccentrics set all the way out. Snooping around on the site leads me to believe my plates were built to the Build 80 dimensions which are evidently a little under size for the wheel spacing. I know I certainly can't slide my X/Z carriage freely like on the Ox videos. I'm not sure if the dimensions for the 80 mm spacing on the Y plates are off as well. My initial plan is to re-drill the eccentric holes at the correct centers, just offsetting them to the side of the original ones. I haven't been able to find what the correct center dimensions are, the only Build 81 drawing I have found are in sketchup and I'm not familiar with that particular package. Does anyone have Build 81 models I can read with Solid Edge or Fusion 360.
