I have not tested this yet, as I am changing my X axis rails and cutting bed.

Using CamBam, how do you set the cutting profile to "spiral down" instead of plunge ? I cannot find any way of setting a "spiral or ramp" down move. The plunge feedrate is set as default to 300. The only thing I can find is the menu "Lead in move" with the 3 settings....Spiral angle / Tangent radius and Lead move feedrate. I haven't got a clue how much to set these at (if this is it) and/or if I need to change the plunge rate to 0 ??
