I am not sure if this is a problem with just my computer or even if its a normal occurrence but I have weird display when nesting. When I load the file (before nesting) it dislays correctly (see first pic) Then after nesting the display shows as second pic and the toolpath shows way down to the left of the screen, as the parts progress the toolpath shows further to the X minus and Y minus directions, see third pic

Hood,
Could you please post both Gcode files so I can test them ? One without nesting and one with...

Thanks, here they are but not sure how you will be able to test the nested one as it points to the file on my drive.

Just noticed that it would plunge way down to Z-5 then rapid so it wouldnt cut very well either LOL. Took all the G code out except G0 and G1 and the nesting works perfectly. It is late here so it will have to wait until morning before I look, but it must just be a wrong G** in there somewhere.

OK still not looked to see what is causing the graphics glitch but am more concerned with the Z-5 part of the code when nesting. I know what the Z-5 is, its my safe Z.
 I did a very simple code for the test so that I could make sure the Z-5 line was still being added when nesting and it is, heres the code before and after nesting, anyone have any idea why the Z-5 is always added? and if it should be there should it not be machine coordinates instead? sorry for my lack of proper terminology, I dont know G Code but am learning (slowly)
