I am rebuilding a voxelab aquila that has been converted into an ender 3.
it has a older style spider hot end and a brand new 0.4mm nozzle. normally I’d take it off and swap it for a stock unit, but it’s effectively glued in place right now so I’m going to set up a new profile for it in cura.
When printing generic pla, with a direct drive extruder, which settings should I change to take the high flow hit end into account?
I’m using cura.
right now the print quality is terrible, when it gets to sections with repeated short prints andonger travel times the flow stops completely. it’s not logged as if I manually feed the filiment it flows freely.
Ah, yeah, “all metal” is specifically about the heat break; whether the heat break has a PTFE liner or not. In general, all-metal heat breaks tend to have heat creep problems for PLA in particular, and are better for filaments that don’t get soft at such low temperatures (that is, almost anything else!)
The main point of all-metal heat breaks is for filaments printed at such a high temperature that PTFE would start breaking down (pyrolysis).
I don’t know whether the new HT-PLA filament would behave better in an all-metal heat break machine. But you might have to wait a while to find out, since HT-PLA went out of stock after a video or two went somewhat viral in the past week or two.
Chances are very good that PETG would work better, yes. It’s what I would try anyway. Especially if you aren’t putting it in a heated enclosure (so no ABS or ASA) and want to keep the current hot end.
right now, I cannot re. I’ve it, the heater and thermistor are stuck in, and can’t get them out to change it without breaking them, and I don’t have any spares.
