g43 Path

with g43, is the path.offset used thru the whole file ? below is a pic of what i'm asking.
the endmill is at x.125 y.125 z1.2 in pic. starting the program it jumps(g49 offsets cleared) on the yellow line.
beginning of file has g49. then "offset start" is g43 h4( tool table x.125 y.125 z1) it jumps to tool table offsets.
then move to x1 along that line. it makes the round. why doesn't it use the path that it took off from ?
Thanks

difficult to answer specificly without the drawing and gcode files and knowing which post processor was used etc
but bear in mind with all gcode , the file is read line by line and acted on , so all offsets are active unless specificly cancelled by using G49
post your gcode file and we can trace through , also let us know which post process you used , they may well be a problem there

also if you are not carefull , it is possible to add offsets to already active tools , if not cancelled and also to machine coords
i tend to set my machines to all zero , and have the cam program store all the tool offsets , so that all changes are in the cam program
but not everyone is lucky that way , it can become confusing tracking down gcode errors

thanks...this is the file. i removed the z offset. and
what's the post processor ? the first line ?
