I opened your file, and converted it to cut path. I too got the same results.
Here is how to fix it..
Before you convert to cut path, zoom way in on the sharp corners. You will notice that the corners look a little funny (Not a smooth line) . Click the line to make it green the hit X (explode) then delete the funny looking part. Press E (edit) grab the end of the logical line to move and press E (end point snap) and click the line you want it to connect too.
Once you do that to all the sharp corners in that group of connected lines. Make one line green and press K (link segments).
Repeat that on all sharp corners in the logo. One that is done you can convert to cut path. But you may not be done yet. Those same corners you just fixed might need a little more work.
Now that its a Blue line.
Zoom back in on a sharp corner, you may see that you have a little criss cross. Simply hit T (trim/extend) and remove the criss cross. You may have a line left over just hit esc. and delete any lines left over. Repeat as needed.
Don't forget to hit K (link segments) after your trim work. Now you will have to convert it back to cut path since your lines are now white, but you still have a pierce point. Simply hit P (Cut Path) and make them all blue. It is also advisable to check that your path goes the right direction with a Cut Preview. If it does not.. click the line to make it green, press K (turns white), press P and the line again. and now it should go the correct direction.
It seems long winded but it really doesn't take that long once you get used to doing it.
Attached is a DXF file in cut path .015 offset. Since a PCM file is invalid for this forum. You still need to actually make it cut path (Blue)
