I agree with @Rodread. @dougselsam’s post is quite on topic and should be reinstated. Indeed New Hot Wire cutting tech topic is related to 3D, as for Doug’s post:
It is an interesting on-topic discussion between simulation and real world which escapes the sagacity of the moderators. After all @dougselsam invented and built several SuperTurbine ™ by using the 3D body method he describes. @Tom, @Windy_Skies, where are your prototypes, your experiments, whatever the 3D method used?
@Rodread’s comment is also on-topic as it refers to an on-topic post which was unfairly moved.
