There are many formulations of Nylon.
Different properties and TG temperatures.
One thing to keep in mind is that they are all hygroscopic. (Like the welding flux discussed above)
Nylon needs to be dry, or the moisture will flash to steam when in the head causing all kinds of problems.
It seems 'Nylon' filament is usually extruded at 260-270C, and I don't know if Bill's printer is capable of that.
