#Primary axis angle description (in machine base terms)
#With nutating (mtype 3-5) the nutating axis must be the XY plane
rotaxis1$ = vecy  #Zero
rotdir1$  = vecx  #Direction
改为
rotdir1$  = -vecx  #Direction

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)

#are aligned to calculate the secondary angle
rotaxis2$ = vecz  #Zero

我改好，程序出出来正确的是B-90,可这个后处理出来还是B90

ggggdddd*

发出来让人帮改就行
