Umbilical on Trident

[logitronica]

I have two questions:
what is best Nitehawk-SB (USB) or Nitehawk-36 (CAN) with an Octopus Pro 1.1 (STM723)?
How do you guys route the PTFE tube? connected to the umbilical or stand-alone?

I cannot answer the first part, but I run them both together. Taping them with some black cloth tape, or whatever color...or even ty-wraps.

Nitehawk SB or Nitewak 36 both use the same USB connection. You would need to choose the nitehawk variant that is the right form factor for your toolhead. The Nitekawk-SB is intended for the stealth burner but the Nitehawk 36 can be used on a wide variety of other toolhead (mine is currently a Dragon Burner with Sherpa Mini extruder.

I also have the PTFE and umbilical separate, I cannot have my PTFE even with slight bending pressure from the umbilical otherwise I will have failures doing automated filament swap with Box Turtle. The PTFE I have routed through the standard inlet in the top back and a support arm to help keep it upright and from getting kinked. The umbilical I have a PUG and mount on the AB motor mount where it would normally come up to route to the drag chain.

I have since switched to 2.5-3mm id (I think that is correct, been a while since I've built a voron, but I have some boxes that need assembling!) on my ptfe feed, and have been pretty happy with the behavior. I used to get some off-brand filament that would vary widely and sometimes get stuck if there were even a slight bend. I stopped using ty-wraps to hold it to my umbilical and used gaffer tape, those zip ties would eventually bend the wall of whatever ptfe I had.
