I just got myself into 3d printing with castable resin and (as many) I am experiencing resin residue which leads to bad casting surface. Nothing major but still I would like to solve this problem.
I have tired increasing temperature but this didnt helped much. So next try would be adding more air.
I have small electric burnout furnace 14x20x16cm. There is one exhaust port on the back. I tried to keep door slightly open but this is still not enough. I know you can drill holes in bottom of kiln but I would like to dont do it if I can.
There is Neycraft Vulcan Venturi furnace which some say works very well for this task. So I would like to modify my kiln to have similar exhaust fan like Neycraft.
Problem is There is no blueprints or pictures of how it is constructed on Neycraft Vulcan. I do not know anyone nearby or any shop who have this furnace so I could look at it in person.
So is there anyone willing to take few pictures of Neycraft Vulcan Venturi exhaust system? I would like to know how it is connected, what is inside fan exhaust duct etc.
Any suggestions and help are welcome
