Hot wire foam cutter - mapping Z and A axes to U and V

I thought of that - but then I would be excluding the possibility of making tapered parts. I have no need for that now - but might in future

I did that - its working fine! Now to sort out the hot wire stretching - a friend uses what looks identical (stainless fishing leader) - but I found out its not, mine is 304 and his is 316. 316 apparently stretches far less when heated
