5-Axis Morph vertical tool error

[Eric]

I'm trying to use the morph tool path to finish the hub of an impeller, the tool path looks good however when attempt to post it I get an error that says:

 

"WARNING - INCREMENTAL C-AXIS MOTION OF -179.745 DUE TO VERTICAL TOOL, ADD RETRACT MOVE? (ADJUST TOOL PATH TO AVOID THIS)"

 

I understand that this error comes up because when the B-axis is equal to zero there is infinite possible solutions for C, I have tried to add limits in the tool path for the B-axis so that it will never be equal to zero however this doesn't seem to solve the issue. Has anyone else had problems like this before that can share some knowledge on how to avoid this issue?

Which Tool Axis control strategy are you using? An easy fix for this is to slightly change the Tool axis control so the tool is no longer vertical anywhere.
