Gotta modify the Goode to finish the holes first, then the block. Right now, that’s a pain to do — I have modify the GCode I get from either SkeinForge or Pycam. The problem is that the tools slice the object, then machine out each slice. So, the final layers get cut through in the wrong order. The last 2 layers should machine the holes entirely through, then remove sections so I can hold on to the piece as it mills through.
