IF and when all this goes well when I upgrade my extruder to the bondtech so I can have a filament sensor for the mmu at that time I will also install a volcano and a .5 or .6mm nozzle. I am totally with you on larger prints coming out decent and in a decent amount of time. In the meantime I have to figure out this new marlin that does not use the Arduino environment. I am all for a print off with you CA. But on this machine. My others all have this problem with artifacts or ghosting in the prints. They come out great dimensionally accurate and stuff. They fit and work great as specific parts I design and print. But if you look at one of my prints for too long I swear it will give you vertigo. That is why I had to stop the LS3 engine I was printing. I cant stand the ringing/ghosting/artifacts, or whatever it is that makes my prints look the way they do. This machine with these high quality parts should correct this. I hope.
