Looking good.
What is the motivation to design an extruder?
Will you be resin casting the extruder as well?
I'm unsure, but it appears that you are using a fixed gap between the idler and hob.
From what I have reviewed most filament drivers are using a spring to allow
the idler to move in-n-out to compensate for variations of filament diameters.
Of the components that are going to be resin cast,
have you allowed for draft to ease removal from the mold?
Looks like a lot of test prints in the background (tu)
Videos are always appreciated!
Hi A2,
The motivation for the extruder is to make one that is easily castable. It is true that most extruders have a spring or something to allow for changes in the filament diameter, perhaps I can incorporate a rubber washer to give some flexing. I have two extruders that work well, one has a spring and one does not. I will be using urethane or silicone molding rubber for the casting so adding a draft is not necessary unless it a very thin and long section. I think I will be good without.
Yea, the test prints led me to discover my hole spacing is not perfect in my print bed, and then the issues with my router which is why I am rebuilding my Y axis.
