How to set correct temps?
Hi everybody,
I have a headbanger (Prusa XL) and Sunlu filament. There is a label:
It says:
Print Temp 195-205°C 50 - 100 mm/s Print Temp 205-220°C 100 - 200 mm/s
I'm confused because it's lenght (mm) , not volume (mm^3). So how should I set the temperature in PrusaSlicer properly? Should I use formula? If so which one? And which values of Printers > Machine Limits should I take for calculations? Maximum feedrate? If so, should I calculate the diagonal speed (since it could travel x and y at 140mm/s each)?
Are there useful online calculator or even database with combinations of printers and filaments with recommendations for PrusaSlicer settings?
Or should I just enter 220°C and that is it?
Best Regards

RE: How to set correct temps?
It’s not volume or length its speed. So one is recommended temps when printing at up to 100mm a second speeds and the second is when printing at higher speeds such as 200mm a second.
Faster speeds require hotter temps to get the throughput. You should always test for your particular machine/filament combo anyway.
RE: How to set correct temps?
Should a small, quick print model be suggested for these types of tests?
RE: How to set correct temps?
I think you're overthinking it. Just try the Generic PLA setting, which in my hands works great with almost every filament. Should you run into a problem, just print one of the many temp towers on printable. But the standard profiles print at higher temps than before, so I think you'll be fine.

So no matter how much volume per second a printer is extruding? I mean there are factors like nozzle size, layer height.
@FoxRun3D: Good idea, I didn't think about the temperature tower.
I'm preping the temp tower. How do I select the second extruder in gcode? Or will the command 'M104 S220' set the current extruder to temperature 220°C? Or all? Or always the first one?

Check out my temp tower at https://www.printables.com/model/39810. There are versions for the XL

RE: How to set correct temps?
Just use first extruder only and place filament there.
See my GitHub and printables.com for some 3d stuff that you may like.
RE: How to set correct temps?
Printing now... the command 'M104 S220' is applied to current extruder.
@FoxRun3D: Your url is broken. Maybe you mean this?

Thank you for your suggestion.
Just curious: I think only one temp tower for each filament type (PETG, PLA, PLA+, PLA-XYZ) for each vendor, no need to repeat for each color of same type. Or am I wrong? What's your experience?
Best regards

RE:
The correct URL is https://www.printables.com/model/39810 For some reason, the forum software loves to include the period at the end of the sentence...
One temp tower per color or not: Depends. Most filaments today behave very well, and the Generic profiles work just fine. But sometimes you find you'll need a different optimal temp for different colors from the same vendor, based on the chemistry used to generate the color. But I rarely run temp towers anymore as 99% of the time the Generic profiles do the job fine.

RE:
I see, thank you very much. 👍 And that is great page you just linked to (didn't know yet).
I also think the generic profile should be fine but before I start multi-day-prints I better want to be well prepared than waste the filaments because of first use of another brands (until now I used Prusament and rarely used different brands for smaller parts).
