Setting plunge depth (Souns like noise issues)

The plugs depth; is set; at .400in and the cutting is done in less then 35% of running time.
plz help!!!

Sounds like you are having your USB-connection drop out, could be from PC power management protocols or RF noise somewhere.

See this search for possible factors to consider:

Just for clarification:

means your cutting stops without being complete?
If so, I’m just going to cite myself :grin:
