I was told people brought in some Fusion360-generated code
that created an error "Radius to end arc differs from
radius start". Nobody has provided me that gcode, so I
have no further details. Google saysa this was a common
issue after a q4 2018 patch to fusion360
Yes, a classic problem. LinuxCNC is strict about the start
and end radius needing to match to high accuracy. My fix to
this is to always use the R word instead of I and J to set
the arc radius, then there is never any way it can't match.
If fusion360 cannot be set to use the R word for arc radius,
then you can try the tolerance adjustment.
