I have been making changes to this printer and so i wanted to update this thread. First and foremost here is my current extruder setup..



I am so happy to have finally found a layer fan that blows all the way around the filament. and this setup keeps the bltouch very close to the hotend for better accuracy. Now I just have to do something about that z belt. If I make the belt too tight it flexes the threaded rods and they bind. If I leave the belt loose half way or so up it skips on one side. Not always but a real PITA when it does it. So I have decided to do away with the belt and convert to dual Z motors. I will upload pictures as that moves forward.
