Hi,
The ramp/helix dressup is quite dummy. The helix algorithm simply looks for a straight down non-rapid movement and a closed loop of constant-Z movement after that. If such condition is found, it is replaced with a helix covering the depth of the original Z depth. So because the original operation (profile in this case) is made so that the first move is made from safe height to the first step depth as a continuous feed move, the helix dressup has nothing else to do than to replace the whole depth with a helix. Like said, lowering the safe height close to the surface of the stock is the best way to avoid cutting too much air right now. Do all the operations have the Start Depth parameter? It maybe could be done that the plunge movements above that height are simply ignored by the dressup.. I'll try to play with that idea some night next week..
