Brass Nozzle vs Steel Nozzle

[bigseb]

I thought I'd give my CR-X the T-800 treatment and replace the standard brass nozzle with a stainless steel one. Big mistake. I know the heat capacity for SS is not as good as with brass but I could not get a single successful print. I tried upping the temp, increasing bed temp, lowering first layer speed, nothing. Ultimately I had no choice but to replace the SS nozzle with the original brass one. Bottom line: unless you really need to print specialty/abrasive filaments just stick with brass.

And, how much lower is the coefficient of friction with brass than with any nickel-bearing material?

Difficult to nail down as material pushed through can affect the result but will most likely be anywhere from 0.012 to 0.29

Nickle-inclusive materials are rarely lower han a 0.3 coefficient of friction. This is the reason that "high nickle content alloys" are so common for railroad wheels.

Never said it was. I responded to your question of
