I had never heard of the Malyan belt fed printer before, and that is an amazing price point for infinite z!
Thanks!
Edit: out of curiosity, have you used the roller extension? If not, have you felt you should get one? In my work I have from time to time felt the need for 8' pieces of trim, and it would be very cool to be able to customize things, whether to solve issues with awkward fit, or to add lettering and etc. My guess is not having the roller extension would cause issues with longer prints due to friction with the part being pushed across my bench, or tipping and causing print failure due to not being supported.
