From our experience, if you can print in ABS with your printer, you should be able to print with Carbon filled nylon. An enclosure is a must, so ambient temperature is high enough (40 and plus), we tend to print the material at 270C, we actually do test the part to make sure inner bonding is good, and play around the temperature, etc…
A small note for the printer if using an enclosure and temperature is high within the enclosure, you have to make sure you motors do not skip if their temperature is getting too hot. We added some thermal sinks on ours. Also, the electronic boards might not be able to work in elevated ambient temperature, so you need to double check (an extra fan blowing internal air onto the electronics might be enough).
Just added a picture of the extruder of one of the printers, as you can see it is a pretty basic one, nothing fancy. The second picture is one small printed part.
