problems in carving

hello along with greeting, 
I have a problem in the engraving using the cnc mostly, 
when generating the G CODE in aspire the simulation is visualized correctly, 
when sending the work in each corner the drill leaves those marks, some advice? 
of configuration in aspire to avoid that problem? Greetings.

You are either moving too fast or have overcut on. I don’t use aspire so I can help much more than that.

How fast are you cutting?

Like Ryan said, it almost looks like you have what we call overcut turned on. In Aspire it’s called dog-bones. Under the fillet menu make sure you have them unchecked, just use normal.
