it’s more an issue with my lack of knowledge, not with the machine or the design. My initial impression is is that it’s a little bit smaller and thinner than what I wanted so I would try to enlarge it. Otherwise, this has been a very successful. First two prints the poop shoot and this no problems one small problem with the poop shoot the green filament got kinked up, locked up and I had to adjust that but other than that no problems. I’m very happy very happy to be a part of the Community.
