Tony,
Make atransition ramp smoother. If a program is making it a sudden
transition, redo it into a smooth one. I agree with one of the other
replies that if you do the TE first that the wire may separate from the
templates at the end of the travel. Stick with what's proven (or use really
cheap foam for a test subject).

Subject: [RCSE] Re: Foam cutting
I am trying to refine my foam cutting technique and am having a problem
getting a smooth cut at the start of leading edge on the top surface pass.
(Elsewhere is OK)
Compufoil template shapes have a horizontal step/ramp up to the leading
edge slope, thus making an abrupt angle transition. This transition seems
to be causing my hot wire to catch and vibrate causing significant ridges
in the cut foam at this important location.
How do you cope with that? Is there any reason I cannot make the ramp an
extension of the leading edge curve to avoid this "angle transition" and
hence "twanging" of the wire??
I do cut the bottom surface first then the top, and start at the leading
edge per compufoil recommendations.
Any help will be much appreciated!
Thanks & regards
