I just downloaded this version, i like the new features but have a few comments.

1) I specify a tool on a layer in LC, tool change appears in Mach3 G-code but when i run the toolpath test the tool offsets don't work .
Yes i checked to see that both tools are defined in M3.

2) I created a new layer in LC and moved all my drill holes to that layer.
exported to M3.  when i imported it back in from M3 to LZ the drill layer disappeared.

3) just being picky.  When you start moving chains to a new layer the default should be whatever the last layer choice was.
EX i define a new layer for drill.  everytime i go to another hole to move to the new layer i have to scroll down and fine drill layer.
stupid me I've fat fingered the mouse and messed up a couple of time.

Your products are great keep up the good work.

It appears that auto clean is the issue in #2.  i can create a drill layer and move all holes to it.  but if i hit autoclean the holes move back to the original layer and that new layer disappears.

I'd like the ability to remove an entire layer if I want to
 
Also I'd like to see the ability to rename a new layer after I've misspelled it originally

I now have my tool offsets working - don't know why they did not before

To delete a layer right click on the layer in the layer tree and select delete... Tell me if that works

Thanks
Brian
