Need advice. I want to print 3mm PLA or PETG with a 2mm nozzle. This won't be on a printer but a robotic arm. I was thinking of a Titan Extruder "clone", and a Volcano hotend. I have 24v PSU.  Oddly, I can find regular 2mm nozzles for Creality, but only up to 1.2mm for Volcano. I'll keep looking. So, I don't waste money on the wrong parts, Does the Volcano hotend work with both 1.75mm and 3mm? I'm guessing i will use (since I have it, a E3D V6 radiator. Now the titan extruders, do they work with both 1.75 and 3mm? My main idea going with Volcano, was extra heat to print 2mm nozzle. Any thoughts would be appreciated. I'm on a budget so these will all be Aliexpress or ebay parts. This is just a fun experiment seeing how to 3D print with a 5 axis robotic arm.

I have used a Titan extruder and two other printer folks that I know have used the Titan and the universal response to "would I use one again" is: "NO".
The Titan seems to grind up its bearings and has a very short "service life" in our experience.
I wouldn't go there.

I do not know anything about the Titan Aero or Titan Aqua extruders, they may have learned to do something better there.
