This style stainless nozzle works great with the stock heater block or V6 standard heater block. This is a standard CR-10 length nozzle. (This is not for the volcano blocks. Volcano blocks use longer nozzles).
Stainless nozzles are great for filaments which are slightly abrasive, such as metal particle filled, wood filled, glow in the dark, and fluorescent pigment filled.
A few tips on usage:
Stainless is slower to gain, and lose heat energy, than brass. As such, you may need to increase your print temperature, very slightly (5C to 15C, depending on your environment and cooling). Speed on your part cooling fan may also need slight tweaking, compared to stock brass nozzle slicer settings. We recommend adding at least 2 additional skirts, or more, to your print. This gives move time for heat to reach nozzle. The thermistor actually measures the heater block, so your nozzle will be slightly different.
