Hey there! I have been looking into this product for a while and I think I'm ready to pull the trigger. I've got a few questions so I'm not blind sided by anything.The first is, what kind of shipping times are typical?The second is, I only need to adjust the G code one time, correct? Or do I need to add it to the profiles and the adjust it based on each print?The third is, does this work with most/all filaments? Or are there some it does better/worse with? I noticed in the FAQ that PLA is referenced mostly and just want to clarify.Four, is there any specific downsides to this product that aren't noticeable at first? I don't do anything crazy with my printer, but do want to know if there's anything I should keep in mind.I appreciate any help and time!
