Hey I saw this new extruder design a little while ago but cant find it anymore and was wondering if anyone knew anything about it. Now i am not referring to what you find when you type belt drive extruder into google. I do not mean that it uses a belt to turn the hobbed bolt, I am referring to one without a hobbed bolt and used a belt to press against the pulley inside the extruder.
Anyone know what I am talking about or anything more about it? Good/Bad? Link to more info on it?
