Ways to increase nozzle temperature

[killmelast 0]

I am new to the Ultimaker ecosystem and I recently acquired a 2+. What's the best (and safest) way for me to achieve higher temperature on a 2+? I came across the E3D V6 mod and 3D Solex heaters so far. Alternatively is it possible to just "upgrade" my coupler and tweak the max temperature setting in firmware? I just want to consistently reach 280C without compromising the rest of my machine.

Have a look at this:

Thanks, conny_g. Yeah, I came across that awesome mod awhile back. I believe they used E3D hotend to achieve those temperatures. Upon re-reading it, however, I think I might be able to reach 280C just by replacing the OEM PTFE coupler. On the other hand, is that a safe modification supported by the controller board on 2+? I would hate to replace the board down the road...

 

Edit: realized the coupler on 2+ is TFM not PTFE. Would TFM support 280C?

I don't think TFM will do those temperatures for extended periods of time, and it's still PTFE-based so you will likely get offgassing.

People tend to do hot end swaps for anything above 250˚C. I've got a drop-in hot end swap design but I haven't tried to make one work with 2.85mm filament yet.

Yeah, I am a bit hesitant to print it that hot for extended periods. I will most likely "upgrade" to E3Dv6 among other things on my list.

This is the tip I got when asking about the PTFE Coupler;

I expect it to arrive today, meaning that I have not tried it yet. 

 

I am not sure though about the fw change to allow the higher temperature, I’m guessing it is tinkergnomes fw that is preferred?
