General Mach Discussion / 4th Axis Right hand rule question
« on: February 11, 2015, 10:27:45 PM »
In trying to get Mach3 setup to run my 4th axis I have been struggling with the Right Hand rule definition. Is the rotation relative to the tool or not.
It seems Mach3 defines +A to be relative to the tool. I have attached a screen shot of the tool path view in mach3 with a simple z down, rotate positive 90. The resultant tool path is RH rule as seen by the tool. What confuses me is that the consensus seems to think that mach3 should be doing the opposite. Also the default output from VisualCAM shows up mirrored in the tool path viewer.
Can anyone provide a clear answer on this? Is mach3's tool path viewer conventional or not?
