i looked at your drawing and it had extra rapid moves. any time you notice extra rapids, you will have broken chains. and when you use the clean function it should help simplify the chains and rapids.
there are a lot of differant things you can check for. most of the time when i save a drawing , i use the export function ,not the save. export as standard autocad dxf ver 12. lcam likes that the best.
in your lcam -setup/load option- set your line tolerance at .001 or .0001 . another thing i do is put a border chain around my drawing, that way lcam has a stable chain to work against. then you just delete it when
you finish. i sent you two files back ,you will see what i mean about the border. when you load the dxf you will see some extra rapids, then use the clean function and you will see it change.then it should look like
the lcam file i sent you. there are plenty of tricks you will learn when you mess with this stuff.
