Ycm 5th axis post edit?

[Nightsky84]

We are using a rotary table with a trunnion attahed to it. I have a fairly simple part to run to try it out. It only needs to rotate 90 degrees thats it. The post processor supports 4th axis and 5th axis. We will eventually be getting into a lot more detailed parts, but we are only going to be using 4 axis for our parts we don't have a 5th. Everytime I post something it posts b90 c90 for the rotary positioning. Is there any way to get rid of the C all together and still make it post correctly? I have tried to just delete it or uncheck it out of the machine definition manager but then I don't get the rotary positioning at all. Any ideas??

Make a 4 axis post from MPMASTER. This allows multi axis toolpaths. Then all you have to do is lock the appropriate axis in the toolpath parameters and you will get good code.

Which post did you start with?

we got our post from our mastercam supplier when we upgraded to 4th axis. I've never used mpmaster how do I go about this?

You should get them to fix it. Not being difficult here, but there is more information needed than you are able to give.

MPMASTER is one of the "base posts" that people start with when making a machine specific post. Others being mainly "generic posts" from CNC (Mastercam). They are different so how this gets fixed will depend on what your reseller started with.

I downloaded the post it actually works way better than the one they gave us. The one they gave us I couldn't even get to run without going through and editing it when it was posted out because it had so much stuff that our machine doesn't recognize. I'm new at the rotary machines so I just want to make it right before I start running something and something bad happens. I appreciate the help! The only thing so far that I would change on the mpmaster post is it wants to send my trunnion to  its absolute home position and I need it to go g90 a0. instead of g28

That is handled in the 'pretract' Post Block.

Make a copy of the line you want to edit. Put a "#" pound sign in front of the copied line (so you have a reference to "go back" if needed).

Near the top of 'pretract', make sure 'absinc$ = zero' (not one). Also, set 'cabs = zero'.
