Hi @Milkdog ,
The current printhead has limited the highest temperature to 230 celsius degree. However the recommend printing temperature for PETG is 230 ~ 250. So you’ll probably need to print at a very slow speed.
Wiki portal for people want to know what PETG is >>
@Simon Any info on this? Would it be a firmware/software update to add a higher temp setting (e.g. run a higher duty cycle on the heater)? Seems like a 15C increase shouldn’t cause any structural or wiring issues with the printhead…
Most of the hotends that I’ve seen with a 230C limit are because they have PEEK plastic inside of them (usually a heat-break or insulator between the hot and cold parts of the hotend) and PEEK has a glass transition temperature near 240 + or - the 10% accuracy of most thermistors… That’s my guess.
How were you able to print at 230º?
I tried it myself but even though I set the temperature both in the main setting as well as in the expert panel, it actually never went above 225º.
Also, the filament load temperature is only 220º.
Any ideas for how to “force” the Flux to truly go up to 230º?
I’ve got a 1 kg spool of Gizmo Dorks transparent PETG, and I’ve tried to optimize settings without success. I can tell that speed is a factor, even at 230 ºC, but I’d really appreciate it if someone could post the optimized settings that can be pasted directly in the Expert Settings window. There was a settings file that someone posted for another printer, but I wasn’t able to make it work. A little help?..
