I have a few question about my TAZ 4.
A little background on my TAZ 4, it has been upgraded to a TAZ 5, (upgrade to the LulzBot TAZ Single Extruder Tool Head v2 - 0.35 nozzle, also upgraded the bed to PEI surface). I have also just purchased an additional LulzBot TAZ Single Extruder Tool Head v2 - 0.5 nozzle and I have the original Buda tool head that came with the TAZ 4. I would like to keep the 0.35 Tool Head dedicated to printing ABS. The 0.5 I would like to use with different types of filament. I also bought a RepRapDiscount Hexagon AO Hotend 1.75mm Kit with 24v Heater Cartridge which I would like to use to replace the Buda tool head setup.
Question: Is the 0.5 nozzle a good one for using with different filaments like PETG, Semiflex, or Nylon or is there a better nozzle size you would suggest.
Question: Is the .35 nozzle the best to use with ABS or is there a better one you would suggest
Question: I am looking for a post that explains how to replace the Buda tool head setup with the “RepRap Discount Hexagon AO Hotend 1.75mm Kit with 24v Heater, Cartridge”. I would like to use this setup for printing 1.75 filaments. It came with 0.4 nozzle.
What new parts do I need to print and what parts can I use from the Buda tool head setup.
What type of hot end cooling fan do you recommend, I have seen everything from a 40mm, to 80mm, to using the squirrel fan and putting a piece of tape around one side of the cooling fins on the hot end.
What is the volts needed for the hotend cooling fan.
Do I need to replace to feeder tube for the filament with a smaller size (to handle the 1.75 filament) and does anyone know where too buy smaller tubing.
I purchase an additional bed glass and heater and put the following on it, PEI (Polyetherimide) Sheet, Opaque Natural, Standard Tolerance, ASTM D5205 PEI0113, 0.03" Thickness, 12" Width, 12" Length. It is working great. I have the original bed glass and heater bed that has PET on it.
Question: Should I upgrade from the PET on the heater bed to PEI. If I do upgrade should I remove the PET or should I put the PEI over the top of the PET. The PET is in really good shape. If I decide to use other types of filament such as PETG, Semiflex, or Nylon should I stay with PET on one bed and PEI on the other or would it be better to just stick with PEI for everything.
Question: Any comments on the best filament to work with if I am looking to make quadcopter frames and parts for my TAZ.
Thanks in advance for all your help, it is really appreciated
