First the postrocessor is junping the Coordinate systems
G53 to G54
NOT a Good idee
only G54 shoudt be in Gcode
THE N YES it is correct as you do a G41 Move Without Circeling in and out
USE Lead In Out
Radius on Off Mode

G53 is fine, retracting my Z axis.
I’m coming from Heidenhain background and nothing like this ever happened to me using RL RR
Backplot is not showing tool compensation I guess....
Lead in and Out will probably solve the problem, but sometimes I have trouble to fit it in to the small hole. For me it is weird anyway, even if it is normal
