Multiaxis link is weird

[Rocketmachinist]

I am getting some weird stuff when I am using multiaxis link. It shows it doing what I want it to do but when I post it throws an error at me the the axis combo is invalid and the values in the posted files comes out weird.

Curve 5 axis in 4 axis output and be done with it. Back plot the last move on one operation and then 1st move on the next operation. Draw your arc or lines and use them to drive the toolpath. Your two lines will be your axis control. You now have a perfect linking move. More work yes, but results you can control.

 

Gcode taught me that over a decade ago and I still use it today.

 

I got the same issue in 2017 and 2018 so it seems to be a bug.

 

Another trick is to use the Multiaxis linking to create the Geometry you want to use for the Curve 5 Axis toolpath in 4 Axis output.

I don't have a 5 axis sim

Open mouth and insert foot that doesn't work either. Going to have to unroll the geometry and use Axis sub to create the motion you are after. I really consider this a bug since even Curve 5 Axis will not work on any HMC Post and axis combination I have tried.

Tested it with the stock MPmaster horizontal, get it in x9 and 2017. However, the post forces a full retract between plane changes. Which is my preference. But mult-axis link should work....
