Trying to do a volume rough, constant load with minimal retract. Volume to be milled is "L" shaped.
Image #1, I've set the Approach-Wall at red arrow. Image 2 is resultant toolpath.
The first leg of the "L" it machines as expected (with minimal retract between climb cuts, nice). However I can't figure out why it is retracting on the second leg to the top surface of the part (actually, it is retracting above the top surface by LIFT_TOOL-CLEARANCE distance of .005").
If I change Approach-Wall to other end of "L", result is the same (image 3).
Now, if i remove all Approach-Walls, it does a helical plunge in the corner, and then does the constant-load, minimal retract path exactly as i would want (image 4). trouble is that i do not want to helical plunge, I want to enter from the approach wall!
seems like having (any) Approach-Wall selected is making it retract on the long run of the "L" for some reason...
