Let us know about your difficulties and how an “air job” (where a file is run w/o the router on or stock in place) turns out at support@carbide3d.com — we have a 10-step plan which works for most folks, and a fallback solution for folks it doesn’t work for — assuming that the electrical supply is stable (all bets are off if you have a refrigerator or other heavy load such as a compressor on the same circuit, or if the transformer in your neighborhood is failing (typical symptom of that is flourescent bulbs going out prematurely)).
