All in all, I’d say the calibration was fine. It depends on how nitpicking you want to get. Also, note that calibrating for one optimal solution on one aspect, may end up compromising on another aspect. This is particularly noteworthy with temp towers and PA Pattern advance calibration.
But if truly want to nit pick, here’s my input. Note, I personally would not expend the energy tuning these items out but for the purposes of exercise, it might be worth doing so solely to hone your own calibration skills.
I’m not sure what the correct terminology is for this artifact, maybe this is the ringing @johnfcooley mentions. I do know what causes it though and how to fix it. This artifact can usually be corrected by fine tuning the pressure advance setting. I’m not talking about using the one in Orca slicer either albeit that’s a great place to start. I’m talking about printing a basic cube and varying the pressure advance until you get perfectly square corners without this tell tale bulge. But again, is it really necessary? That’s a matter of personal preference in my view.
In this example with the angle of the light, it’s really prominent.
It’s not as prominent in the other filament but still present.
I have no idea what happened here but I’d rerun the check just to make sure it’s just not an anomaly. At any rate, I can’t explain it.
These here indicate one of two possible problems. Either it’s moisture in the filament(rare for PLA) or you need to do a flow rate calibration. Either way, these gaps don’t belong and it would be worth further filament tuning in my view because they will likely look worse in larger prints.
Now I generally prefer the Voron Cube since it gives me more lines to deal with. To me the only thing that the Bambu cube does is promote the Bambu logo but I guess they have to do that.
Here’s an example I ran today because I have a new spool of 3DjoHor PLA that just isn’t printing worth a damn. As I often do, I start my test using the stock Bambu PLA Basic profile. Why? Just as a reference point. The black cube on the right is using the Bambu Basic profile and you can see the red circles showing serious flow rate issues but then again, this wasn’t a Bambu filament. The one on the right was using a previously time-test calibrated profile for the 3DJoHor PLA I had used many times before. Unfortunately, it did not fair as well in the pressure advance department as the yellow arrows call out. Will I fix it? I’m not sure if I will take the time.
BTW: The one in the center is the new Bambu PETG HF. I didn’t have a profile for that so I used the one posted here and tuned it from there. As you can see, it is nearly flawless except for the overhangs at the bottom of the hashes marked in green. But its PETG printing at 0.28 so now I’m really getting nitpicking. The point here is, when is good, good enough or in Mandarin, 差不多 (chà bù duō).
