A axis overtravel on vertical set up

[AndrewNg]

I tried to make a setup as picture 1 witch WCS on the center of the hole on cnc mill 5 axis (x, y, z, A, C). control gave me an alarm overtravel on A axis because nc code call for A -90 degree to cut on side. the reason to do the setup it is easy for me to find zero at the center of the hole. 

then I moved the WCS to new location as picture 2, verything work smoothly, but it turned out super hard to take the location.

is there anyway to make the control run setup as picture 1. thank you

Is the control on your machine set to move the axis in the shortest direction?

Posting a Zip to go file will make it easier to look at everything in your setup.

Need to have the MCD(Machine Control definition) default the mi4 to 1 to always post Negative A values. Right down it is defaulting to 0 which will always try to output Positive A when the machine needs Negative A.

You highlight all operation can right click and make the adjustment to this file with edit common parameters.

The other thing is the post is not setup to support different C & Tplane locations. They must all share the same Zero point. They are not and I suspect that is what is giving you the posting issue. Use the center of the rotary as the Zero for all 4 planes.
