@HaDe: Thanks for the links. Have you tried Fiber glass paper as insulation. I've been using that on my Plastibot Mendel with good results. I bought the fiber glass from McMaster P/N 9323K21. I'll give the 120W a try. I'm printing my 3DR on ABS so hopefully that plus the fiber glass insulation will be enough.by citro - Delta Machines
