Stock Ender3 V2 nozzle temperature can be set to maximal 260°C. However, is not recommended to use it over 240°C. The reason is that end of the PTFE tube is in heat block and that high temperature is not good for the teflon for longer period. All metal hotend by Micro Swiss has teflon tube ending in heat sink, this means we are not limited with this problem. The Micro Swiss package will also arrive with hardened steel nozzle, so we can print abrasife filaments too (like Glow in dark or Carbon fiber filaments).
This new all metal hotend is able to 3D print on temperatures above 260°C. In second part of this video I edit and updated the firmware, so it can be set to higher temperatures. Since I couldn't find information about maximal operating temperatures for heater cartridge and termistor, I set the max temperature to 270°C so far.
