Joe, Classified part so no. Let me if if i can work up a dummy rep showing my issue.

Paul, Was going to try your modified VMC.mmd but our firewall is blocking you site. Reason for restriction: Forbidden Category "Games" Go Figure I'll see if I can get our I.T. guys to unblock it.

Paul, Sorry but I disagree. The mill 4 - axis hmc.mmd comes out of the box (I just installed X3 on a new PC to double check this)with the rotary axis set on y and the B zero point set on Z-. This is the correct setting for an HMC. This is how my part is set up. The XYZ values are posting correctly but the B is off 90. If I rotate my part (about Y) in MasterCam so the tertiary datum feature of my part, in this case a hole CL, is in line with the WCS x axis instead of z as it should be and is on the machine, the post output is correct. So again, why is the post outputting the b zero from WCS X when the mmd is set at z and why, when I change the zero point in the mmd to something else is it not effecting the post output? I'm working on the assumption that by changing the B-axis zero point in the mmd the post output should change as well. This is a 5-axis drill toolpath on a cylindrical part using the 4-axis output format.

Thanks for all the input but im still not there. Refer to my original post & reply. This is a fresh install of x3 using all mastercams default MD, control and post for a 4-axis horzizontal. I have edited nothing. The part is setup in Mastercam exactly as it would be on the machine. I,m in top plane & the CL of the part is the y-axis. XY & Z all post correctly. The B is 90 degs off. The B is posting with the zero point set X+ axis (default WCS) The MD has the zero point at Z+ axis which is correct. So my question is why does changing the B zero point in MD not effect the output of the post. I've been using MC for a long time "V7" so I certainly know how to get this to work I'm just trying to get a handle on this machine def thing they started with X.

My part in mastercam is rotating about y. I transformed the part in mastercam to be the same as the machine CS. I was trying to avoid having to use a differant tool plane or wcs in Mastercam just to simlify things. Everything xyz) posts fine except the B zero deg pos which I can't get to change. What bothers me is I used MC's default config for a Generic HMC which is configured the way it should, changed nothing and the B rotation is wrong.

In the machine definition the B-axis zero deg position is set to z+ as it should be on a 4-axis horz with a b-axis rotating about y. The post is outputing the rotation from the WCS 0 deg which is x+. Changing the zero deg pos in the MDM is not affecting the post output at all. Am I doing somthing wrong here. Go Figure. MILL 4 - AXIS HMC.MMD GENERIC FANUC 4X MILL.control GENERIC FANUC 4X MILL.pst
