Ive seen it mentioned here that one of the Golden Rules for building your own machine is to make sure you have 'built in' adjustments.
Whats the best way(s) of doing that?
Oversize holes or Sloting holes, depending on the application?

Would you over size the holes in Gantry Plates when attaching to Gantry Extrusion?
It seem counterintuitive to me, to achieve a ridgid connection, but I understant to concept and the need.
