Pushing Sprite extruder Pro to 350°c

Wondering about pushing nozzle temp max to 350°c in order to print PPS - CF?

Given 400°c thermistor and bi metal heat break. Is it possible to edit firmware etc. Is it “advisable”?

I should have said, the Sprite extruders i have are on a CR10 Smart pro and a Ender 3 S1 Pro. Both are in enclosures with fume extracts etc.

Anyone know how i can push nozzle temps up to 350°c?

Bit of a bump… How to push Sprite extruder Pro on an Ender 3S1 Pro to 320°c

Anyone?
