FS#2558 - Offset trajectory path issue with circular Lead In/Out

Andrew,

Please refer to related forum topic:
https://www.qcad.org/rsforum/viewtopic.php?f=74&t=10724#p44206

An eighth circle with radius 8 Lead In/Out relates to nothing in the actual exported cutter trajectory.
Nor does it with the edge being cut.

Proper examples and a comparison with ‘Extension’ type Lead In/Out included.
Conclusion: IMHO connecting the cutter trajectory and edge being cut is wrong.

It looks a lot like turning on Cutter Compensation (G41/42) while the motion is circular.
But that is uncommon because most controllers can not cope with this motion.
One can increase the offset gradually along a straight pre-entry segment for turning on G41/42 but not along a circular path.
Also see snippet:
- Pre-entry C→B turning on G41
- Circular Lead In B→A

Regards,
CVH

Had to redraw this from scratch.
The explanation and pictures in the topic should speak for themselves.

A few (sub) layers can be set visible to investigate a partial detail.
Bitte.
