  OK, let me put it this way:
  Most  common  format  for  number  format  in drill files is 2.3 but
  different  programs generate different headers in their output files
  where  should be stated are suppressed leading or trailing zeroes or
  no zero suppression.

  So  for everybody, please send me a small drill file (besides Protel
  99SE  which  I'm  using) so that I can figure out different headers,
  and write a freeware Excellon->GCode translator.

  Also,  please  include  your  wish list, i.e. canned drill cycles or
  pure G0, G1 mooves, Spindle controll, Stop for tool change.....

  In  Files/CNC/Conversion_Programs/ folder of this group you can find
  a program that I wrote quite long ago in M$ QBasic.

  Just  checked  the  output  of  KiCAD, it spits out coordinates with
  decimal  point,  and  can  do  it  in  Inch and Milimeters, but also
  without   decimal   point   leading/trailing   zeroes   suppressed,
  fortunately, all relevant information are present in the header.
