  1. I did. I was given the MP post documentation and told that post editing is outside the scope of their expertise.
  2. Hi all. I am trying to set up a post to add a trunnion with B and C axes to a 3 axis mill. I have gotten the correct outputs for the rotational axes but have run into some trouble getting the offsets configured correctly. The chuck face is 7 inches above B-axis center of rotation but setting saxisz to 7.0 is giving me an offset in Y instead of -X. Any Idea why this might be happening? # -------------------------------------------------------------------------- # 5 Axis Rotary Settings # -------------------------------------------------------------------------- #Assign axis address str_pri_axis : "C" str_sec_axis : "B" str_dum_axis : "A" #Toolplane mapped to top angle position strings str_n_a_axis : "A" str_n_b_axis : "B" str_n_c_axis : "C" #Machine rotary routine settings mtype : 0 #Machine type (Define base and rotation plane below) #0 = Table/Table #1 = Tilt Head/Table #2 = Head/Head #3 = Nutator Table/Table #4 = Nutator Tilt Head/Table #5 = Nutator Head/Head head_is_sec : 1 #Set with mtype 1 and 4 to indicate head is on secondary #Preferred setup is pri. zero matches sec. zero/direction #Zero machine and determine the planes perp. to axis rotations #These plane combinations are valid: #Primary plane XY XZ YZ #Secondary or XZ XY XY #Secondary YZ YZ XZ #Primary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis must be the XY plane rotaxis1$ = vecx #Zero rotdir1$ = -vecy #Direction #Secondary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis and this plane normal #are aligned to calculate the secondary angle rotaxis2$ = vecz #Zero rotdir2$ = -vecy #Direction #NOTE: Use of 'top_map' requires the dealer match the # above settings below.
