Hi, I have different print profiles with different print speeds ranging from 50mm/s to 250mm/s. So I was wondering, should I print the temperature tower tests in the orca slicer with each print profile and therefore the speeds you intend to print at?
To me this would make sense (and means a hell of a lot of work), because I always read the printer needs to print at higher temps due to its speed. So, when I print slow with this printer, it does not need the high temps.
What do you guys think?
The answer can only: It depends!
The print speed, and with it the flow rate of the material DOES influence the required temps. The higher the flow, the higher the temps need to go with the same nozzle.
But depending on your material, you can still get crispy results without absolut perfect settings, so it very much depends on what you are printing, which materials you are using and do you require the absolut best results or is “good enough” just good enough for you.
For PLA, unless you overheat it, the differences should not be that big for enough. Though PLA and some other plastics change their surface appearance depending on the heat, so printing slower with lower speed will give a shiny surface while lower temps or higher speeds will give it a more matt finish.
I second the answer from Thrawn 
I see the calibration tools more as a ‘worst case’ scenario to identify where are my max settings are.
There are materials where you want to achieve a certain look or the layer adhesion goes wonky where it may make sense to go the extra mile and also slows down the printer. But here I would limit the speed more with the volumetric flow - as it slows down the printer without touching the printing presets itself.
Thanks for the quick replies! Well, then I can tick this of the list of important things to get spot on and rather make sure flow and PA values are well calibrated.
I am looking to get the best surface quality, which means mainly surfaces being smooth without ringing, patterns and wobble. And it is interesting how different Bambu basic PLAs print. The grey seems so different to for example white and black. The surface looks more uneven (with a stark light on a shallow angle:) with the excact same settings. Might just be that it is more matt then the other two.
Black and dark colors hide imperfections so much more better then light bright colors. Sometimes the quality is the same, just the perceived one not.
Other then that, color actually has an influence on the print settings, even if usually only a small. But specially white requires large amount of titanium oxide or rarer zinc oxide. The color pigments then have a real influence on the filament behavior.
For Bambu Lab there is another factor. We have no idea who actually makes the stuff, and if everything comes off the same factory or even the same supplier. It might well be they have different suppliers for the same material and then the behavior would almost certain be slight different.
Thanks by the way for helping me with another problem by helping someone else:)
Do anyone know how to set up a temperature tower like this in Bambu?
The printer is excellent for engineering parts but adjusting print settings just takes too long, and can waste quite a bit of expensive filament!
Sorry - just found this adapted to bambu, and the designer also has speed and acceleration tower
