Title: she's fat outside just right indide
Post by: docltf on September 19, 2007, 06:07:19 PM

attached are my files---xml---pocket---lay

pocket cuts fine finish size should be x=1.254 y=.574, finish cut is x=1.253  y.573 the difference is the tool bit that's ok.
lay cut dos not come out right using the same tool. i switch stock and program during same setup.
lay cut finish size should be x=1.250 y=.570, the finish cut is x=1.256 y=.575  that's a pretty  good difference from inside to outside cuts.
i noticed this about a month ago it pockets a great 1" round hole but a fat 1" round lay.

BRIAN
   
       is it possible for me to access the backlash routine in mach3.when i enter my true dial indicated backlash number into
      the backlash menu and run a cut  the part measures .006 fat.i can go back to the backlash menu reduce the lash .006
      and the part will size.the phony lash numbers will let me cut a good square but a nasty circle.the true lash numbers will
      cut a good circle but it will be large and the square off.can i get to the lash code and try to work it around.

thanks bill
