I think you are testing too much at one time. try to work on one problem at a time. Maybe use some of our downloadable test files that you know work to isolate problems.
The laser turning on when you hit generate code - This has to do with the ttl controller being designed wrong. There is a hack to add a resistor or cut the board if you want to go that far.
Burning a hole in the table - I always use a piece of steel as large as my whole machine. That way I never make the mistake I made when I made a nice puzzle box design in my brand new bamboo top workbench.
Jpgs, bmp, png - all of these go line by line, printer style, or raster (whatever you want to call it... we mostly use raster) unless you click trace then it draws the lines you select as a continuous line.
Trace - trace wont reorient your piece. There are other things that can though. Where you choose your start point is one. lower left, center, upper right, etc). Once you get to the gcode sender you need to tell the machine where this place is by setting home. home is where the start point is (lower left, center, etc.) Before you hit send you should ALWAYS turn the power to 5 (or some low number it is default 255 but for this you will need it to be probably below 50) then select engrave frame. This will show you the frame in which your engraving will be in. It wont burn because your power level will be too low. This lets you get a feel for where you will be engraving. Whenever I skip this step I regret it. Additionally if your piece is flipped in the x or y axis it could be reoriented this can be changed in the settings.
Dxf - share your file and let us take a look at it. Maybe your problem is something we can fix or maybe you will need to switch to a different diagramming software... but I doubt it.
