Why is the V6 Max Temperature so low?

I thought that the V6 would be able to reach super high temperatures! Why do all the firmware guides tell me to set my maximum temperature to 280°C?

Is this a good question?

The metal components of the V6 can go up to 350 Celsius before the structural integrity of the aluminium is compromised. The standard thermistor also has a max temperature of 300 Celsius, so to print at really high temperatures, a few modifications need to be made.

Firstly, the thermistor can be replaced with a pt100, which has a max temperature of 400 Celsius. This will bring the max temperature of the V6 to that of the aluminium, which is 350

To go above 350, you'll need to replace the heater block with a plated copper heater block and the nozzle with anything other than brass. Either plated copper, stainless steel or hardened steel. The stainless steel is for food and medical application and hardened steel is for abrasives. If temperature resistance is all you need, then get the copper plated nozzles. Doing this brings the max temperature of the V6 up to the temperature sensor again, at 400 Celsius.

To go above 400, you'll need to replace the temperature sensor with a thermocouple. You'll then be free to go up to 500 Celsius.

Be aware that the silicone socks will degrade quicker is used above 300 Celsius.

Does the max temperature change if I am using a bowden V6? (assuming I have all the other upgrades like the thermocouple and copper block)


@binterryan76 The max temperature for a Direct and Bowden V6 setup is the same. As mentioned above the first limit is the thermistor (285°C) next is the aluminium heater block (320-350°C)

If printing with temperatures above 300°C a recommended safe setup for the majority of use cases would be PT100, plated copper heater block, and nozzle X. This would give you a maximum printing temperature of 400°C if you require above this use a Thermocouple instead of a PT100.


What heater cartridge is recommended for temps <=400C?
