I am confused due to ironing quality for frame surface. When nozzle moves perpendicular to the wall (short distance) it is geat result but for parallel it is completely different structure. I disabled dynamic flow calibration and surface is flat now but structure is different. I also did test with 45deg and it is strange to see how ironing went from good to bad surface quality. I do not know is this setup issue or nozzle moves different for short and long distances (printer’s driver optimalization).
So, before digging deeper into the problem, your Irgoning generally doesn’t look good. It’s okay, but not great - and by that I mean the parts that you describe as good - regardless of the problem you’re describing.
Have you calibrated your Irgoning for the filament? You have to do this for every filament you use:
To me, it basically looks like the filament / ironing isn’t calibrated; after that, you can still investigate the problem you described if it still occurs.
That looks like a really, really bad ironing setting. How did you determine the correct settings? Remember, each filament requires different settings. Example: I have some that require 15/20 and others that require 20/25.
By the way, if you’re struggling with ironing, there are alternative solutions, such as chemical treatment or using a heat gun carefully. You just have to be careful not to heat one place for too long.
@RetroSharky the problem is the slicer. It won’t do true monotonic path.
It’s a problem that’s very infuriating and Bambu refuses to improve with. Regardless of how good your ironing settings were finetuned with, as long as there are travel moves on the ironing surface, the ironing result would look like shi at the “travel seam”.
In subtractive manufacturing world the terminology is called region connection.
It would require the ironing to pass the gap with a lift, a rapid motion and an engage. It will be a more time consuming process due to the additional travel. Especially in the case of the OP. The continuous lifts might cause marks on the edges also.
But simply giving the user the choice is better then giving none at all.
Yeah, sure, but take a look at the photos anyway - and I mean the “good” spots. To me, the ironing definitely doesn’t look calibrated. Of course, that worsens the overall impression.
With the right settings, significantly better results are possible even with these types of forms.
Ironing is just a last resort anyway - in my personal opinion. There are much better options, but I’ve already mentioned those.
