and submit it to the EMC and watch the motion using backplotter.
(view-backplot) Watch the motions on each of the plots so that you get a
good idea which way they go. Then submit it to the machine and see if the
motions are the same. If not, change the backplot settings and try it
again. When you have directions that show the same plot as you are really
cutting, you can edit x,y,z in tkbackplot in your plat/linux???/bin file so
that it always runs the way your machine does. (Or send me a note off list
with the settings and I'll make you a backplotter that works for you)
I would then take a little time and get used to testing a g-code file
with backplot before I tried to mill it. because backplot should show what
the machine is going to do.
Some of the programming stuff on linuxcnc.org in the handbook may help a
bit with understanding g-code.
