Hi Greg Your the man. You gave me the bump I needed(I think) Got every thing to display correctly. I changed the Primary Axis to B and the Secondary Axis to A and eureka!!!!!!! Now to give it a dry run on the machine. Thanks again for your Help. Deon

Hi Greg Thanks....Realy appreciate your time and effort to try and help. I will double check those settings and report back. At least I have another angle to look at this in an affort to get it working. Your help is really appreciated. Thanks Deon

Hi Greg Thanks for the reply. You are spot on. Now if you say Haas does not follow the standard rules what do you meen by that. Witch axis is A and witch Axis is B in the setup I need, maybe I've got that wrong. Can't the axis numbers be changed in the post.Ive got movement on all the right axis numbers but the left right rocking throw the toolpath out. The post is a generic Haas 5Axis post. I have also tried the generic Fanuk 5 Axis post as said in my first comment but as stated there are very few differences when you compare the posts. This is and exract from the post #Table/Table configuration: # All 3 axis offsets are supported. # #Table/Head configuration (only primary table/secondary head): # Axis offsets are supported on primary axis. # #Head/Head configuration: # All 3 axis offsets are supported for non-nutating machines. # Only the primary to secondary axis offset is supported for nutating machines. Table/Table configuration All 3 axis offsets are supported.(Does this mean rotary or linear) Acording to the following what do they mean by #Zero and "# direction" #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$ = vecy #Zero rotdir1$ = vecx #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$ = vecx #Direction #NOTE: Use of 'top_map' requires the dealer match the # above settings below.

Hi Newbie asking PRO HELP!!! Jumping into deep water. First I need to clarify. I do not own a Mastercam seat but have access at my day job. The trunnion is selfmade mod(for cyl.Head porting)on a old haas trunnion . Here follow some the code from my Haas 5 Axis post were one is supposedly being able to change the axis alignment of your rotary axis combinations. This is for a normal trunnion. A rotating around the X Axis and B rotating around the Z Axis. I need to change this to a rock and roll type trunnion for cyl.head porting..... So A should stay the same but B or C should Rotate(Rock) around the Y Axis. At least that is what my head thinks I already tried to change the Machine definition and machine control to set the appropriate rotations but the out put stays the same with one device rotating around the Z Axis. A comment from Superman taken from a nother thread on the net........ H, we have similar transom, but the B is aligned along the X axis, which makes it an A address, limits are A20 to A-110 When our 4th axis=0, the 5th axis is perpendicular to the Z, this makes it a C axis address ( C rotates around Z ), limits are C0 to 360 This could be your problem ? Remember to use the WCS of the part drawn in TOP view of the setup ( with all axes set to zero ), and T/C planes to be how the tool "sees" the part relative to this WCS" Maybe a similar problem........ I am sooooooooooooo confused!!!!!!!!!!! I need help with changes to the following line numbers.......... N16 N32 N33 N37 N38 N42 to N45 And any other changes you might think necessary. At least this is what I think might do the trick. I have tied various combinations but just cant seem to get it to work. This post is working perfect on a normal trunnion. Another though.......... could the way I draw the part influence the tool path?????????? I have really been trying for almost 4 weeks before asking for help. Comparing the Haas 5 Axis post with the Fanuc 5 Axis post shows they come from the same writer with some small changes. Tried both but still no luck.

Cimco canot be set up for the rock and roll setup so the toolpath display is hay-wire no matter how you change the post. Putting my trust in Moduleworks shows the toolpath only wrong when changing the Moduleworks machine setup to rock and roll. I do realise the post is madeup of two parts(*.pst and *.psb)I can access the .pst but not the .psb. Scared to try it out on the mill, dont want to crash on a moonligthing job :-) Thanks for any help in advance Deon
