[new print head pt100 wiring]

I ordered a new AA 0.4 print head.  It came with the heater wiring but not the pt100 sensor wiring.  What am I to do?

Do I need a 0.4 or a 0.6 print core for 2.85 mm filament?

[use of carbon fiber filaments]

I want to use carbon fiber filaments to make some replacements parts for motors and sports vehicles,  We have an S5 bundle.  Will the printer work with carbon fiber?  Any recommendations on the type of filament?  I see that many are made with nylon base or is ABS base better?  Any recommendations on the extruder head?
