When you did the program did you do it if it was 1/2 steel so the M102 line looks like M102(HRS0.500) and than change the material thickness on the cut condition page to 1.00? Because we set up a wood condition that every time we cut a sheet the head would retract and never come down next thing you know the head is 2 inches off the sheet. The cause was it never gave me a good post some lines were missing like the M103 (pierce line).
